Z CAM E2-F6, S6 and F8 – Budget High Resolution Cameras Ready for Pre-Ordering

News

by Mark ZdunnekAugust 14^th, 2019

The Z CAM E2-F6 with 6K/60fps and the F8 with 8K/30fps were unveiled by the Chinese manufacturer based in Shenzen during last NAB. Pre-order is available now and shipment scheduled for October 2019 already. Also in pre-order now and detailed in this article: the new Z CAM E2-S6 with 6K/75fps! From what we know so far, they are very aggressive contestants in the megapixel war, including impressive claims of dynamic range, RAW and other aspects alike.

Z CAM  E2-F6 – Full Frame 6K Cinema Camera

The full-frame CMOS sensor camera priced at just under $5,000 comes in two hardware variants, one for each of the widely used EF and PL lens mounts. It is thereby advancing from and getting rid of the MFT sensor of its predecessor the E2 4K camera and also moving away from the WDR sensor with a dynamic range choice option.

The F6 is claimed to reach 15 stops of dynamic range and controllable via Gigabit Ethernet connection as well as capable of live streaming through the same cable connection. The sensor supports dual-native ISO with 400 ISO and 2500 ISO bases.

The camera films up to 60fps in 6K and reaches 120fps in 4K, recording onto CFast 2.0 cards with up to 300Mbps (in H.264 and H.265 equally). Both frame rates are only possible in cinemascope with an aspect ratio of 2:4:1 and 10-bit color depth. Fascinating enough, the 10-bit recording is only 4:2:0 color subsampling (in H.265 and H.264 alike).

Until the moment this article was written, the table presented on the company homepage states that ZRAW is supported, but leaves the column empty. Further information on bit depth (likely also 10-bit) or color subsampling, Mbps and more are currently vague.

Let’s take a look at available resolutions and maximum frame rates:

• 6244×4168 @30fps max (6K Open Gate)
• 6144×3240 @48fps max (DCI 6K)
• 6144×2592 @60fps max (DCI 6K 2.4:1)
• 5760×3240 @48fps max (6K UHD)
• 5552×4164 @30fps max (5K 4:3)
• 4992×4160 @30fps max (5K 6:5)
• 4096×2160 @72fps max (DCI 4K) *
• 4096×1728 @120fps max (DCI 4K 2.4:1)
• 3840×2160 @72fps max (4K UHD) *
• 3840×1620 @90fps max (4K UHD 2.4:1)
• 1920×1080 @120fps max (FHD)

* Cropping / Supersampling selectable.

Z CAM  E2-F8 – Full Frame 8K Cinema Camera

Some features are noteworthy and different from the F6. These include the actual physical sensor size of the F8 which is indeed slightly smaller with 35.97mm x 23.99mm in comparison to the 37.09 x 24.75 mm size of the F6. While the maximum resolution of the F6 is 6244x4168px (6K Open Gate) witch multiplies to 26MP (26,024,992px) the max resolution of the F8 is 8192x3456px (DCI 8K). The latter multiplies to roughly 28MP, while the sensor of the F8 truly boasts 61MP, just like the recently announced A7R IV. Other than this, the dynamic range of 14 stops (F8) falls a bit short compared to the 15 stops of the F6.

The most noteworthy differences are the resolution and maximum frame rate choices of the F8:

• 8192×3456 @30fps (DCI 8K 2.4:1)
• 7680×4320 @30fps (8K UHD)
• 6144×3240 @30fps max (DCI 6K) *
• 5760×3240 @30fps max (6K UHD) *
• 3840×2160 @30fps max (4K UHD) *

* Cropping / Supersampling selectable.

Z-CAM E2-F8: details

Why the list is so short and why 4K DCI or other essential options seem to be missing (or are at least missing in this enumeration) are currently unavailable or unclear. The same is true for specific details about crop factor, questions on line-binning and more. The reason why this sensor only does up to 30fps at every presented frame rate (even QFHD) and why the table depicts an HDMI 2.0 Type-A output with 4K at 60fps, 10-bit and 4:2:2 at the same time is also unresolved. At the same time, 60fps is not available as an internal recording option! We’ve already reached out to Z Cam to clarify this matter.

Z CAM E2-F6 & F8: Two Cameras – Same Functions

A piece of extremely noteworthy information is that both the F6 and F8 cameras are not displayed as “Apple ProRes certified” as their predecessor the E2 4K. The lacking currently certification is undoubtedly also is the reason why both cameras lack the ProRes 4:2:2 (HQ, Standard 422, LT and Proxy) recording options. These were much-endorsed pro-user features of the E2 4K. We’ve reached out to Z CAM and the company informed us that they would get “ProRes 4:2:2 licensed for 6K and below” for internal recording in the future. They are also working on 6K RAW @ 30fps as well. A timeframe for the availability hasn’t been disclosed so far to the best of our knowledge.

Both cameras record onto CFast 2.0 cards in exFAT file format only and feature the same set of connectivity options ranging from HDMI 2.0 Type-A (video output up to 4 @ 60 fps with 10-bit and finally 4:2:2 available here) via USB 3.0 Type C (data transfer, camera control), 2x COM-Ports, 2.5mm SONY LANC compatible remote control, a 3.5mm stereo audio in and out. Also, a very nice feature for pro-users is their 5-pin LEMO port for dual-channel XLR microphone, since the cameras record 24-bit 48kHz audio. WiFi 802.11n (ext antenna) this time with 5GHz capability (an improvement from the 2.4GHz of the E2 4K) is also available in both cameras.

While the Z Cam E2-F6 has the same body dimensions as the 4K, the F8 has 10cm more depth and is this slightly larger. Aside from regular video recording both new cameras also feature time-lapse video and sport Rec.709, FLAT, HLG and Z-Log2 gamma curves to choose from as well as the focus modes autofocus, manual focus, and continuous autofocus, just like E2 4K.

Z CAM  E2-S6 – Super 35 6K Cinema Camera

The Z CAM E2-S6 that was already listed on the company website earlier is now also available for pre-order. It sells for $2.995, and the main differences to the F6 model are its smaller Super 35mm CMOS sensor measuring 23.4 x 15.67 mm with 14 stops of latitude (1 stop less) but the same effective pixel count. Aside from this, the only significant difference lies in the maximum frame rates, available at specific recording resolutions. I have compiled the following list to show the slightly higher frame rate choices, available with the E2-S6 over the E2-F6.

Same resolutions and frame rates:

• 6244×4168 @30fps max (6K Open Gate)
• 6144×3240 @48fps max (DCI 6K)
• 5760×3240 @48fps max (6K UHD)
• 5552×4164 @30fps max (5K 4:3)
• 4992×4160 @30fps max (5K 6:5)
• 1920×1080 @120fps max (FHD)

Differences:

• 6144×2592 (DCI 6K 2.4:1):
  • F6: @60fps max
  • S6: @75fps max
• Only S6: 4096×2160 @30fps max (DCI 4K Low Noise) *

  • F6: @72fps max
  • S6: @75fps max
• 4096×1728 (DCI 4K 2.4:1):
  • F6: @120fps max
  • S6: only @100fps max (Author’s note: All resolutions where maximum frame rates differ have higher frame rate capabilities within the S6, just in this case, the F6 outperforms the S6. There is no information available to us why this is the case.)
• Only S6: 3840×2160 @30fps max (4K UHD Low Noise) *
• 3840×2160 (4K UHD) *:
  • F6: @72fps max
  • S6: @75fps max

Z CAM E2-lineup: S6, F6 & F8 camera bodies and comparison

All three cameras, the Z CAM E2-S6 for $2,995, the Z CAM E2-F6 priced at $4,995, and Z CAM E2-F8 for $5,995 are available for pre-order now. I’m very excited and hopeful to get my hands on the actual products at the IBC 2019 in Amsterdam (at the latest).
