It means the website most likely did not test these cameras side by side, but simply took existing information and repackaged it with a few unique sample images. You can see obvious examples on any website that lists “banding” as a negative for the Z6 or Z7, yet not in their review of the EOS R. One or two big websites publish a set of high-quality tests several others copy the pro/con page and hammer out a watered-down version of the original review. So, how did it happen that the Z cameras took most of the heat for this type of noise? A large part of it is due to the trickle-down nature of camera reviews.
After all, the root cause of these banding issues is generally due to on-sensor phase detection pixels, which are part of the autofocus system in nearly all modern mirrorless cameras – making this more than just a single company’s problem. However, I can’t help but feel some surprise that this issue became so strongly associated with them, yet is hardly mentioned in discussions of other mirrorless options today. It might not be the most real-world of tests, but part of this job is figuring out how these cameras fundamentally work, and-Ĭough, cough! Who underexposes images by six stops? Ahem.Īnyway, the Z6 and Z7 certainly aren’t perfect in terms of line pattern noise. I definitely don’t begrudge initial reviewers for writing about the Z6’s and Z7’s line pattern noise when the shadows are boosted too much. Here are the same four images one more time so that you can click and compare without the circles covering them.
Although you can see a bit of line pattern noise in some of the gray color swatches on the right, it is far from objectionable.

This is largely due to the lower base ISO of 64 the other cameras here would likely show similar performance if they offered such a low native ISO. Just for good measure, here is a sample image from the camera that sparked this discussion, the Nikon Z7: NIKON Z7 + 24-120mm f/4 58mm, ISO 64, 1/100, f/8.0 Certainly not what you would expect based on the articles online. In terms of line pattern noise, though, it has perhaps a slight bit more than the A7 III, and definitely less than the Canon EOS R. The most noticeable thing to me is that it appears greener than the other photos – but that’s something you can correct with a small white balance adjustment. I’ll cut out the act now and show how the actual Z6 sample image compares: NIKON Z6 + 24-120mm f/4 58mm, ISO 100, 1/160, f/8.0 The Canon EOS R has a decent amount, and the Sony A7 III has a bit as well. But the two examples above go to show that line pattern noise isn’t a Nikon-only factor. This time, there is noticeably less line pattern noise, although it’s still visi-Īll right, I’m kidding around. Once again, I underexposed this photo by six stops, recovered it in RawDigger and Capture One, and then circled the offending noise. However, just because the Nikon Z6 has these patterns of noise doesn’t mean that…Īh, sorry – it looks like the image above isn’t from the Nikon Z6, but from the Canon EOS R. I’ve circled the most obvious patterns: Canon EOS R + RF24-105mm F4 L IS USM 58mm, ISO 100, 1/160, f/8.0 As you can see, there are indeed visible lines of noise, although only in certain parts of the image. I opened it in RawDigger, then exported as a TIFF and recovered the image with the “Exposure” slider in Capture One. The following image has been underexposed by six stops at base ISO 100. But now that we have performed complete dynamic range tests on today’s mirrorless cameras at Photography Life, my question is… why? Although most reviewers were quick to point out that 5-6 stops of shadow recovery is excessive, this issue nonetheless drew a lot of attention.
One of the big headlines when the first Nikon Z6 and Z7 tests appeared online is that they exhibited a pattern of “banding,” or line pattern noise, when recovering shadows too much.
