Zacuto Z-Finder EVF test – Full Review

Zacuto Z-Finder EVF test – Full Review

Using the Zacuto EVF on the new Sony NEX FS-100

As most of you might already have heard, Zacuto has released a new electronic viewfinder (EVF) for use with your DSLR cameras or any other cameras with an HDMI connector.


EVF – the race to market

To be perfectly honest I was skeptical about the entire EVF craze when RedRock Micro and Zacuto first announced that they were going to build and sell EVFs over a year ago. RedRock Micro was the first to announce theirs, and only days later Zacuto started making a big fuzz about their announcement. Well, one could get the impression neither of them had an actual product at that point, playing cat and mouse.

Interestingly, over the months that followed, slowly leading up to this year’s NAB (where I had the opportunity to try out the Zacuto EVF for the first time), any news about a RedRock Micro EVF had completely died away. Zacuto on the other hand kept people informed about the development progress, and loads of working pre-production units were all over the floor at all sorts of booths at NAB 2011.

There is one other noteworthy EVF on the market now from Cineroid, which makes a decent impression, but I haven’t used it yet. Check out Philip Bloom’s review of the Cineroid EVF right here.

I just checked RedRock Micro’s EVF site – they are saying that their EVF was delayed (without giving any timeframe for a release), and that all the other EVFs on the market are too expensive – “our target is $375”.

The Redrock Micro EVF still seems to exist solely as 3D low-poly model in a computer ...

Well, I love RedRock Micro products and own some of them, but to be honest, that sounds very unrealistic. If it would be that cheap to produce I think we would already have seen a bunch of HongKong OEM producers jumping on that bandwagon, but I haven’t seen any half-decent viewfinder in that price range at NAB, so I conclude that it’s currently simple not feasible. The RedRock EVF also still sounds more like a concept in its early stages than a real product, especially considering the fact that they still only have really bad low-poly 3D renderings on their website instead of photos of a mock-up … I’m sorry, prove me wrong, but I don’t think we will see the RedRock Micro EVF anytime soon (if ever).


Why an EVF?

Well, I am surprised it took accessory manufacturers so long to react to one of DSLRs’ most obvious shortcomings with regards to ergonomics. From professional camcorders we are used to have an electronic viewfinder that can be adjusted to anywhere you please. That allows you to position the camera where it needs to be for a particular shot, while maintaining the possibility to have a good look at what you are actually shooting.

The form factor of a shoulder camcorder was proven to be the right one over and over again - that's what we strive for in our DSLR rigs now as well - an attached EVF is obviously needed to position the camera away from your face.

The fact that you can view a DSLR’s image only through its LCD (except for cameras without a mirror like the GH1 or GH2 – but those are technically speaking not DSLRs) means that also need to have to add a viewfinder like a Z-Finder or Letus Hawk VF to the screen to judge the image and focus. I think I have done the most thorough series of DSLR viewfinder reviews to date, check the links out below – all the main viewfinders available on the market have been tested (review of the Cinevate Cyclops will follow shortly). I found the Zacuto Z-Finder and the Letus Hawk VF to be the best ones available, for different reasons.

– Letus Hawk VF – comparison to the Z-Finder

– Varavon Pro Finder

Such mechanical-optical viewfinder add-ons are great, but their biggest problem is the fact that you cannot position them where you want them. You are forced to have the camera right in front or next to your face, even with flip-screen cameras like the 60D or T3i/600D.

Another big problem is that Canon makes it really hard for us to accordingly judge focus because on some cameras the resolution of the screen is relatively low (e.g. 5D Mark II), plus there are absolutely no focus aids like peaking or false colours on Canon DSLRs. All that mechanical-optical viewfinders can do is to magnify the LCD screen (and by doing that, also magnifying all its downsides). Don’t get me wrong, it helps immensely and I have said before that a viewfinder is the single most essential accessory especially for handheld DSLR shooting, but it of course is always restricted by the camera’s limitations (and its LCD).

Example of a rig configuration with the Zacuto EVF

An EVF completely frees you from the camera itself, while still giving you all sorts of additional options missing from the built-in screen.  You can position it anywhere you want, allowing you to build very custom rigs. I also like the fact that it allows you to have the same high-quality viewfinder on all sorts of different cameras, as long as there is a HDMI connector.


Zacuto EVF

Testing the Zacuto EVF on set

Let me be clear from the start: I was given a pre-production version of the Zacuto EVF to beta-test it on actual shoots and give them feedback on what they could enhance. This review will be updated and expanded further as I will work a lot with the final version of the EVF in the coming weeks.

I think it’s great that they are reaching out to a group of professionals in that way because only shooters know what it’s all about as we work with camera gear every day. That sounds like a very obvious thing to do, but unfortunately it isn’t – not even for camera manufacturers – but I sense even the big boys Sony, Canon & Panasonic slowly realize the importance of listening to the community (good example: the new Sony NEX FS-100, partly based on feedback from cinematographers like my buddy Den Lennie).

Working with a pre-production version obviously means that not everything will be perfect, that’s why I can’t go into detail about all the menu items and different options at this point – they are still making adjustments based on our feedback. By the way, firmware updates for the EVF will be provided for free by Zacuto, and I also expect them to consistently add presets for new cameras just like they already did during the beta testing process. (The EVF has a USB port to allow easy upgrading.)

Firmware upgrade options

While I have to postpone a detailed run-through the menus until I receive the final production EVF, I can give you a rough idea of the Zacuto EVF and my thoughts on it.


Impressions, the screen & built quality

When I first heard Zacuto was building an EVF I wondered if they had the skills to pull it off, because they are known for building great quality camera rigs, but not electronics, which is a totally different ball game.

Gorgeous high resolution LCD on the Zacuto EVF

Obviously they have found the right people to do the job though: the screen is pristine, at 800 x 480 on a 3.2” bezel the resolution is drop-dead gorgeous – if I was Zacuto, I would call it “Retina Display” like on the iPhone 4 (though I’m perfectly sure an Apple lawsuit would follow on the spot). The viewing angle is extremely wide (170 degrees, and I can confirm that), and there is no discernible colour or brightness difference no matter how far you move to the side of the viewfinder.

When you hold the EVF in your hand the first thing you notice is its lightness – that thing weighs almost nothing and therefore also adds very little weight to your entire rig! I think this is hugely important as a lot of rigs (particularly the lower-end options) look great, while weighing extremely heavy on your shoulder.

The built quality is hard to describe as you really need to hold it in your own hands to appreciate the craftsmanship that went into it. To sum it up, I would say it feels as solid as any Zacuto gear I’ve used so far, and that is a huge thing to be said about something as fragile as electronics. It does not feel like other monitors that are usually clearly not designed to go into your gear bag without additional protection It’s more like the rigid enclosure of a heavy-duty pelican case.

Zacuto proved the EVF’s durability already by dropping it from a ladder and doing all sorts of tests with it – check out the videos below. It surely is impressive and I think this piece of electronics will last for a long time.

Z-Finder EVF! If you are seeing this please upgrade your Flash Player at

Zacuto’s Z-Finder is one of the most useful DSLR viewfinders, and it’s a smart move on their side to make it a part of the new EVF, enabling existing Z-Finder owners to only buy the EVF itself (the “EVF Flip” or “EVF Snap” versions), saving quite a bit of money.

I am testing the Z-Finder EVF Flip version, which allows you to flip up the Z-Finder from the EVF, revealing the EVF screen without magnification – a good idea as others will still be able to see what is being shot if you flip away the Z-Finder.

There is also a slightly cheaper option, the EVF Snap, which allows you to snap the Z-Finder onto the screen when you want to use it as an EVF. Works like the old “sticky mount” solution of the Z-Finder directly on the camera screen.

Port-wise, there is the ability to loop through HDMI (6 pin connector, that’s the big one, not the flimsy one featured on the Canons themselves), which is great – you can attach another monitor or viewing device at the same time, giving your director or client a chance to see what is being shot too. A must-have on any professional HDMI monitor if you work in teams.


Menu settings, firmware features & upscaling

Lots of camera presets so you won't need to worry ... or make your presets!

The Zacuto EVF was made to work with DSLRs. It works with all cameras that have an HDMI-out (also new large-chip camcorders like the AF100, F3 & FS-100), but it really shines when you attach it to a DSLR. There are presets for all sorts of cameras (Canon, Panasonic, and so on), each one designed to deal with the peculiarities of a specific camera. For example, Canon DSLRs shift their aspect ratio and most of them even the resolution when you hit record. The EVF will upscale the 480 line image coming from any 5D Mark II, 550D, 600D or 60D when recording, even interpolate in real time. You can compare it to a BluRay player that is able to upscale regular DVD’s to make the image look more HD-ish and sharper. It works the same way with the EVF, and Zacuto did a really good job on that.

This is a hugely important feature as the low resolution HDMI output of Canon DSLRs other than the 7D and 1D Mark IV during recording is one of the biggest reasons that make it very hard using an external monitor on all the other Canon cameras. The upscale quality is superb, and it really helps tremendously when focusing – I did some test shots wide open on an f/1.4 prime lens and tried to shift focus with the EVF and with a normal little 5” monitor, and the results with the EVF turned out to be more precise in most cases.

Nevertheless, focusing always remains tricky on DSLRs with a very fast lens, but there are other features to help you out: peaking and false colors.

The peaking feature enabled

The peaking feature artificially sharpens the edges (just for preview!) even more, making it easier to spot the area in focus. This has become particularly relevant now that the Technicolor picture profile found widespread acceptance (it produces the flattest image you can get out of a Canon DSLR, which gives more latitude for post processing, but that also means focusing is even harder than before).

On the Zacuto EVF, there are 3 steps of peaking intensity that can be selected. I played around with all of them, but I find the lowest intensity (1) to be most helpful for my needs. It is a tremendous help when you shoot wide open, but don’t judge the overall image from it, it’s really just a preview.

The pixel-to-pixel feature shows you the full resolution of the image on the 800*480 screen (obviously cropping out the middle part)

Another focus aid is the pixel-to-pixel feature (also neat to be enabled by the push of an assignable button). It allows you to accurately judge focus by zooming into the frame, revealing only the central 800×480 pixel part of the image in its one-by-one pixel glory.

False colors - looks weird, helps tremendously to judge exposure when put on an assignable button

The false colors feature was introduced with one of the latest firmware upgrades for the EVF. It’s a feature known from professional monitors – different colors represent different levels of exposure. It makes it very easy to judge exposure in different parts of the image and it should only be switched on for a quick exposure check as it makes the image completely impossible to judge aesthetically.

Zacuto really thought about a lot of stuff when designing this thing – 3 of the four side buttons of the EVF can be assigned to custom functions. Putting false color on one of the buttons works great for me, and so does peaking. You don’t have to go through all the menus to use the functions you require most – a quick push of a button, adjust focus, push it again and you’re done. Awesome.

The 4 buttons on the side not only allow menu navigation, 3 of them are assignable - very useful in daily shooting life!

Another great feature are zebra patterns, which allow you to judge overexposed areas quickly and easily. Like the false colors feature this was brought over from professional broadcast camcorders. Very helpful for people who don’t like to use exposure meters (like me).

People using anamorphic lenses have a hard time on DSLRs as the image will appear to be skewed as there is no way to change the displayed aspect ratio on the cameras themselves. The Zacuto EVF has a solution to un-squeeze them shots in preview.

There are many other features on the EVF that make it a perfect little package, but these were the most important ones.

Monochrome display - a feature requested by many old-school broadcast cameramen, makes focusing easier for many


Battery life

The Zacuto EVF runs on a single Canon LP-E6 battery (or an optional external 12 Volt adapter). Another smart move, because that means you can use the same battery as in your 5D Mark II, 7D or 60D. No need to worry about buying back-up batteries as most of us will already own a few of these.

Now, to cut a long story short, battery life is insane. I used the included battery straight out of the box and it lasted for several hours without needing to recharge. After I recharged it the first time, it lasted more than an impressive 7 hours! Now that is what I call longevity!

Prost! Shooting break with the EVF 🙂



I had a hard time finding any downsides about the Zacuto EVF, and I’m still looking. It’s a very impressive demonstration of what can be pulled of if you listen to the customers as a company, and Zacuto is obviously very good at that. There is not much that I would change, if anything at all. Of course, there is always more you can add, but for the DSLR shooter, this really is the ultimate viewfinder.

It not only makes shooting more flexible, but also tranforms DSLRs into more professional movie machines in so many ways, alleviating many of the cameras’ downsides. The Zacuto EVF feels like a natural extension to any DSLR, as if it has always been there … and I truly don’t want to miss it from any of my DSLR shooting in the future. And I think that is the best recommendation I can make. Great work!

The Zacuto Z-Finder EVF is in very high demand, that’s why people have to wait for their orders for a while already – so hurry up to get your order in if you want one!

To support my review work and this blog, please order through this link. Thanks so much!!


Great combo with the Sony NEX FS-100 ... making an awkward form factor much more usable


I am affiliated with Zacuto and I get a small commission off any sales referred from my site. I only recommend products I really like, and that’s actually why I decided to become affiliated with Zacuto. Buying the EVF through any of the links on this site helps to maintain this blog and allows me to use as much time as I do on testing gear and providing these reviews. I appreciate all your support a lot.

Just to make myself perfectly clear, I am also affiliated with some of Zacuto’s direct competitors, for instance Letus, for the exact same reason: I like their products. Being affiliated with competitors proves that I am not favoring one over the other – it really all comes down to the quality of their products, and I will tell you if I don’t like something. It has happened before!

    Thanks for the great review!
    Do you what the best way is to get the EVF in Austria?

    • This shop in Vienna is the official Zacuto reseller in Austria:

      But I would order directly, the reseller prices are considerably higher and with the current $ rate it’s much cheaper, even with duties.

      Also, the EVF is in short supply, so it will probably take much longer for the resellers to receive any noteworthy stock until Zacuto has fulfilled all their outstanding orders. That’s my guess!

  2. Kalle P.

    Hello from Finland!

    I’m wondering why the price tag for every different model of Zacuto’s EVF is 100$ on

    On this page: , there stands that the cheapest model is 675$.

    So by ordering NOW, do we get the EVF for only 100 bucks?

    I guess I’m wrong but there it stands…

    • If you read carefully you see that this is a deposit only! They charge you the rest when they ship the EVF out.

  3. Laurens

    About the ‘retina’ display… The EVF 800×480 is indeed not that much different from the iPhone’s 940×640 (which is bigger). I don’t know how the screens would compare in real ife, but the description sound really really good.

    • I compared them side-to-side and they are really very similar – the viewing angle is also similar.

      • Laurens

        Uff, if it is similar to the iPhone 4 I want one :). Just to nag, how does it compare to a slightly bigger Marshall?

        • Good question – I have the 5″ Marshall with HDMI and quite like it. It really doesn’t compare to the Zacuto EVF though because it EATS batteries (burned through 3 x 4 eneloop AA’s within 7 hours on a shoot last week, and it wasn’t even turned on all the time). Also, it seems to always squeeze the image when recording because there seems to be no adjustment for the drop in vertical lines as there is on the EVF. (I could be wrong on this one and I just haven’t found that setting yet though, really should go through the manual of it … will report back with a review 🙂 ).

      • Did you get my comment sent a couple of days ago?

      • I mocked up a diagram that compares the monitor sizes of 3 EVF’s. Worth a look!

  4. This is the most complete review of the Zacuto EVF I have seen and answers a lot of question I have had.

  5. Martin

    Thanks for this useful report. Comparing the viewfinder screen to the Apple Retina display is brilliant and very, very helpful for me. I own the newest iPod touch and always thought it’s display is great.

    I suppose when you look at the EVF screen at 2.5x magnification you still see the individual pixels. Is that really no problem?

    This EVF is the first Zacuto product that I consider to buy but I’m just a bit sceptical because people raved about how useful the Zacuto viewfinder is on the 5D screen and when I saw it in person the experience was horrible.

    • You have to look close to see individual pixels, but they are definitely there – of course, because it is magnified that much. The resolution isn’t the problem, it’s what the cameras are outputting – and you only get 480 lines when recording on a 5D, 550D, 600D … (every Canon except the 7D). The EVF does a great job interpolating pixels and making the image better, but it still has to work with what the camera delivers it.

      I understand your experience with the Z-Finder on the 5D, that’s simply because the screen of the 5D is the worst of them all resolution-wise. After all, it’s the oldest “Video DSLR”!

  6. Please don’t give any excuse for these Zacuto guys (and niche companies like them) to price gouge. Red Rock is right, these “pro” products (a fictional term) are way overpriced and consumers (who are also “pros”) are getting pissed.

    I’m excited to watch Zacuto suffer and finally lower their inflated prices.

    • I honestly don’t think the EVF is overpriced – have you compared to competitors? Especially in the EVF field they are not really much cheaper, but the quality of the display usually isn’t comparable. You always get what you pay for. And of course, you also pay for a lifetime warranty, but I think it’s worth it, and a proof that the products are very solid – otherwise they couldn’t afford to offer such an extensive warranty.

      Don’t get me wrong, I am looking forward to gear getting cheaper, but as long as there is no competitor with a really interesting product there’s not much to argue about. I’d love to see that Redrock EVF for the price they are anticipating, but the history of their development doesn’t make me very hopeful, it feels more like they’re guessing an ideal price. We’ll see.

  7. Hi, wondering when your Cinevate Cyclops review will be out? Looking forward to that! Thanks!

    • Will edit and post the video review as soon as I’m back from Majorca from our Masterclas nexr week!

      • Hi there, any word yet about the Cyclops? Thanks!

        • Yes, the video review is done, just waiting for Cinevate to get back to me before I post it. Hopefully later today!

  8. Ronald Vonk

    Hi Nino! Good review, I enjoyed reading it! Thinking about getting one of these in a couple of months after seeing it in use on Mallorca.

    SmallHD is also working on one which looks quite nice. Still only 3D mockups though so could be a while before they release it.

    • Thanks Ronald! Yep, Small HD make great stuff too, their monitors are the best. Looking forward to it!

  9. Great write up and thanks for the disclaimer on the bottom, I am glad when bloggers disclose that kind of info.

  10. Having been using mine for a week and love it. Only complain I have is the HDMI cable that plugs into the camera can easily break off if it’s hit the wrong way. I’ve already done it once! There’s not a lot of flexibility there. (the one that attaches to the unit is on a swivel, which definitely helps)

    • I agree. Not much Zacuto can do about that, though – talked to them about it: They are dependent on the cables that are available on the market, and they simply haven’t found one yet which swivels at both ends.

  11. Bob Gundu

    what HDMI cables work with the Zacuto??? I bought the monster super thin ones and it doesn’t work! I have heard that the Zacuto EVF is very particular with the cables.

    • I just used it with the included one so far, works fine of course – I’ll try it with another cable as well and let you know.

    • Ok. Ignore my comment about Monster Super thin HDMI. I just realized that these cables are directional and I had them plugged in wrong. So… they work great!

  12. Ben

    Nino, How good is the peaking feature? That’s the only reason i’d buy the EVF. I shoot a lot of races (5K, 10K, half-marathon, etc) and esp. for finish line shots really need the abiltiy to quickly determine focus on a moving runner and follow focus with the runner.

    Can i do determine focus very quickly with the EVF alone as well use it to monitor my follow focus, or do i need the EVF plus the z finder pro to really make it work? i have a 60D if that makes a difference. Thanks for sharing your impressions.

    • I think it’s quite good, but you should definitely try before you buy. You definitely need a Z-Finder as well as otherwise it’s a very small monitor, making it impossible to judge focus on it.

  13. Dear Nino,

    Thanks for the review. Could you please tell me what the weight of de EVFPRO including battery is. It is very hard to find that information on the net.

    Thanks, David.

  14. Hi Nino,

    Thanx for all the interesting information.
    I still have a question: I have both: the Sony NEXFS-100 and the Zacuto Z-finder pro. I am very happy working with this stuff but there is one problem: I only get audio en TC signal in the EVF monitor. And I should love to see the others signals as focus and iso etc as wel. I can only see the camera signals in the LCD panel of the Sony NEXFS-100 but not in the EVF. When I tried this with an other (Canon) camera there was no problem en the EVF recieved all the information from the Canon camera which was connected with the same HDMI cable as when I try it with the Sony NEXFS-100. In the settings of the EVF I use the Sony NEXFS-100/700 preset mode. And all signals out. So I hope you can help me for nobody knows over here.
    Have a nice day!

    A desparate woman from Amsterdam 😉
