Nikon ZF vs Nikon Z8 Video Quality (Sharpness, Color, Noise) 

Thank you for watching.

Thank you. We might come back to the ZF in the future.

There isn't much to configure codec wise on the ZF. 4k 10 bit 420 is your best and obly sensible choice. It löoks gorgeous and organic right out of camera. Files are small, but it is a lot less sharp than many down sampled higher res cameras and you have less room to mangle the footage. Then again, you don't need to an I find that extremely refreshing. BTW the stabilization is excellent.

I guess you mean 'fixed ISO' with two amplification levels in the sensor. There's a website called something like photons to electrons that tests noise levels and reveals the effect of this principle. The way I understand it, is that the Bayer sensor - analogue and colour-blind - has photocells (diodes) connected to an electronic circuit that builds a charge during exposure and when the sensor is read, the Voltage of the charge is measured. This can be amplified in line with ISO, but as subject contrast decreases with lower light levels, you need less contrast envelope (the dynamic range available to the single shot/frame). So why complicate an amplification that keeps up with ISO? This will work as long as you do not defeat it. If I am right then you should be able to visualise this in extremely bright light where you reduce light level with a, say, 10x ND filter. For the 45MP Z 7ii, Z 8, and Z 9 sensors, you will see that the noise level runs up with ISO until almost 400 ISO and then at 400 falls back to ISO 100 again. So at 1600 ISO you have comparable to that almost 400 noise level. The problem with noise is though that 90% of the noise we see in renditions of our images follows from inadequate deBayerisation in the raw processing software we use. And the Bayer noise is a bigger challenge for that software in the case of cameras without OLPF. Nikon started about 10 years ago with cameras that no longer had an OLPF (D800E), but Adobe only last year gave us "AI Denoise" that does the deBayerisation better but still gives too many digital artefacts (or you can say it retrieves details i sufficiently). For a couple years, Topaz and DxO (PhotoLab and PureRAW) did much better than Adobe Camera Raw (ACR - does all the raw processing in LrC and Ps).

There might be a slight difference in mid-tone contrast but it's not super noticeable.

Yes. 8K sensor

Thanks. NIKKOR Z 28-75mm f/2.8

@@cinematools9621 You obviously didn't use the best lens for testing.

I didn't do any tests, you responded to the wrong post

We don't go over 3200 ISO when filming.

@@cinematools9621 4000iso second basic iso and less noise than 3200. read manual

@@cinematools9621 4000 is when the dual gain ISO would've kicked in and cleaned up the image.

@@herry.with.an.e wasn't aware of it.

28-75 2.8 zoom

@@cinematools9621 Thank you! And great job with the comparison! The Nikon Z f has been on my wish list. I’m hoping to pair that with the Z 24-120mm.

I wouldn't call ZF soft but compared to Z8 it's definitely not as sharp. We're getting Z6III soon and the video should be available next month.

@@cinematools9621 fantastic-looking forward to it!

It has internal Nlog.

Little bit of a missed chance. Dual gain starts at 4000 iso at the Z8 would have been nice to see ;)

The test shows the difference in sharpness/details. The frame rate is irrelevant.

i thought it was the other way around, preferring the Zf
