Z Cam E2 In-Depth Review

Z Cam has leapt deep into the cinema camera field with the E2.  In many respects, it’s remarkable that this Micro Four Thirds camera is as polished and ready for prime time as it is… after all, the E1 is its only predecessor.  In this review, I’ll be giving my general impressions of the camera, as well as a comparison with mirrorless and DSLR cameras, since many prospective buyers will be coming from this world.  I’m going to look at some of the questions I couldn’t find answers to before I bought the E2, how it might change your workflow, and some of the quirks you should keep in mind before you buy it.  It’s a camera with a ton of features, so we’re going to divide this review into three posts that will appear daily.

There are four basic areas that I believe a video camera should be evaluated:  image quality, flexibility, ease of use, and dependability.  Let’s dive right in.

Overview

The Z Cam E2 is a budget priced camera that packs a surprising amount of features and capabilities.  It has a MFT sensor with an ASIC chip that’s designed to run cool—an important characteristic in the tiny body of the E2.  The body is indeed very compact, coming in 3.59″ x 3.90″ x 3.50″, and the chip doesn’t need a fan to keep things cool.  It’s a “brick brain” form factor, which means no monitor, no internal battery, and no real place to grip the camera.  All of these need to be built on.  It does come with a 1”x1” preview screen that’s surprisingly useful.  (More on that in a bit.)  The price point is $1999 as of this post.

Form Factor

The camera brain – brick form is something you have to be ready to embrace.  It’s a much different workflow than a mirrorless system or a ENG camera like the FS5.  Unless you’ve got a weird shaped bag to pack it in fully kitted, it’ll take a couple of minutes of setup time.  It’s a pretty quick process, maybe 2 minutes, but that’s a big difference from a mirrorless that is up and running in 5 seconds.  The camera is more challenging to hold while making adjustments; it’s even more difficult to fish it out of your pack without a handle.  And I expect this awkwardness will translate into more scratches on the body.  It has an impressive plethora of ports, though please, Z Cam, make port covers for this thing.  You couldn’t possibly take it out into the desert like this.

The E2 has 4 programmable buttons, and that’s really enough.  You can quickly access the settings you change most frequently.  The menu organization is about average for a camera like this.  In some respects it’s organized more clearly than a DSLR or mirrorless, but there are so many options—some of which are dependent on specific settings— that it’s really a different kind of “lost in the menu” that happens.  For example, proxy files are possible in some resolutions and not others, so if want to have a proxy file you need to adjust the other parameters first.    

People say it, but it bears repeating that the E2 is a dense little brick, weighing in at 1.67 lbs.  It’s surprisingly heavy, and this can affect your gimbal use.  And because it’s not as wide as DSLR, mirrorless, or Blackmagic camera, it makes balancing the tilt angle a challenge.  With the Zhiyune Crane V2, I added a counter weight to make it possible.  A little Velcro makes it easy to take the weight on and off, but it also ads to the overall weight that the gimbal can support.   While I can do most of the basic moves without straining the gimbal motors, I hesitate to push the motors to far.  For smaller gimbal users, this is a definite consideration. 

The E2 can auto-focus native lenses, but, well… all reports so far have been that it’s not useable for continuous focus.  I don’t have any native lenses, so I can’t test for myself.  The short answer is don’t expect to take any selfies.

Image Quality

If you read the user reviews for the E2, people are almost unanimously happy with the build, functionality, and image quality.  There’s always someone who prefers the features or look of another camera, but that’s just people.  And truthfully there are some issues with ZRAW, their proprietary raw format, that I’ll get into, as well as some limitations with the image quality at 240 frames per second.  But if you want an overall assessment, I have to agree the other users. 

Without getting into the specs, I’ll say that it’s both impressive and comforting that the E2 can produce video files that are both higher and lower in bit rate and quality than most cameras, including the Blackmagic 4k. There’s huge amount of flexibility in file types.  You’ve got H.264, H.265, ProRes 422, and ZRAW which Z Cam claims is 12 bit, 4:4:4.  You can drop down to 10 megabytes per second in h.624 if you really want to save space, or push out 300Mbps in ProRes.  It also shoots 160 fps in 4K, and 240 fps in full HD, 10 bit, h.265 format.  There are over 100 fps/codec variations (check them out here) And unlike most cameras, it records audio at every frame rate. 

Out of the box, the 709 colors are quite beautiful.  They’re similar to Nikon DSLRs, which are slightly muted in comparison to Canon, but still true to their original hues and very easy to tweak in post.  Green is a slight exception here—those hues tend to be more saturated. 

Skin tones are exceptional.  By comparison, the colors on the Sony a7 series are a total pain.  I’ve begun to understand that image quality has two major characteristics: color rendition and roll-off.  A beautifully rendered scene can still appear harsh and 2-dimensional if the roll-off in the highlights and shadows is abrupt.  The E2 handles both color and roll-off exceptionally well. The images are sharp, too. You can see the image profiles and dynamic range chart for more info on the E2 setup.

Z Cam also has a 4K Low Noise Resolution option that I’ve yet to explore.  More on that, possibly, later.

ZLOG2 is a solid flat profile that’s easy to grade.   ZRAW is their proprietary raw format.  It’s 10 bit, 4-4-4, with a constant bitrate of 1.2Gps-- which in theory is great.  But Z Cam says it’s tweaked for maximum detail rather than dynamic range, so it’s not great for wide dynamic range scenes with a lot of shadows that need to be pulled up.  You’ll get noise.  This is a bit problematic, because one of the main uses of raw footage is heavy grading.  And being a new file format, none of the software editors can work with the footage. You have to convert it with Z Cam’s software.  This isn’t surprising, and I’m sure it will soon be possible to edit directly in your software as Z Cam develops relationships with Adobe, Davinci Resolve, and Final Cut.  Blackmagic went through the same process with BRAW, after all.  But in general it feels like ZRAW isn’t quite ready for general consumption.  It’s more for a niche use when you’ve got a well balanced scene and you want to get the best quality image.

Frame rates up to 160fps are consistently beautiful.  At 240fps, however, the image quality becomes inconsistent.  The camera is capable of gorgeous footage, but becomes noisy if under exposed, and it can have difficulty with high-detailed scenes.  Some users blame pixel-binning, but I’m not sure what’s going on.  I plan to do more testing.

Being a heavier camera, you experience less micro jitters when going handheld.  Rolling shutter exists, but its better controlled than my Sony a7 cameras and most DSLRs.

I give the image quality of the Z Cam E2 a 9/10, with the loss of a point being for those challenges at 240fps and ZRAW.  This is a bit unfair, because many similar cameras don’t offer either, so 240 is really a perk.

Tomorrow: Flexibility and Ease of Use.
