p.1 #1 · Sony A7II in low light? opinions feedback wanted
I have a Fuji X-T1 which I'm totally happy with, but I been hanging on to my 6D with the 40mm 2.8 and 200mm 2.8 for that full frame look at 200mm @ 2.8. I been thinking about getting a Sony A7II for the full frame and IBIS. How good is the A7II in low light from ISO 1600 to ISO 6400. The X-T1 is not too bad but is there a lot of difference in noise in the A7 II compared to the X-T1 or 6D?

Pretty good. Its as good as any non-Sony mirrorless. Truly, the only issues I see on my new a7II (so far) is ISO 6400 for locking af. Everything else tends to be great.

The A7 series with the exception of the A7s and A7Rii are all not superb at high ISO. The A7ii sensor is the same as the original A7 with exception with the faster AF ans low light focus ability. Compared to the 6D, the A7ii will be lacking at higher ISOs. I own an A7ii and am looking for a 6D specifically for low light AF and better noise at higher ISOs.

The A7 II is 'good' at high ISO, but not exceptional. It's really only around a 1/2 stop better than the X-T1, and perhaps not even that. However, with the higher resolution, you'll resolve a bit more detail, and the IBIS will allow for the use of much lower ISOs if you're not using a stabilized lens. In those cases, of course, there's a big advantage.

Some of the samples I have seen online don't seem that impressive compared to what I can get out of the X-T1. I wanted real world feedback and hoping some of you have used or own both. I'm going to assume the A7RII is better? Is the A7s that much better with stills? I know with video is good but not sure if it still applies to shooting clean high ISO pics @6400

The A7R II is around a full stop better than the A7 II. I think the A7 II does fine at 6400, though. There's noise, for sure, but it is more than usable for most situations.

From some high ISO examples I have seen I believe the A7s is around 1.5 to 2 stops better than the A7R II, even with the A7R II images down converted to 12MP.

Also, i heard that Fuji cheats with it's iso for about 1 stop, so i guess that means that your iso6400 is more like iso3200. Haven't had Fuli myself, but saw video comparison between Fuji and Sony and there was a difference in shutter speed at the same settings.

It's better than Canon but worse than the high-end Nikons and A7Rii/A7S. So it's about average for a full-frame sensor. The A7II will still beat any APS-C or M43 camera in mid to high ISO.
With the A7II, I set my max to ISO 3200 for stills. ISO 12800 with the A7S. Tolerance for noise is highly subjective.

This is not about base iso, its about inflating higher iso values to make images look cleaner. I found that then i wanted to buy x100s, there a lot of threads about this matter, which i found after watching the video i mentioned. Got ricoh GR instead so haven't tested fuji, so i can't be sure about this whole thing. Also, dxomark shows differences between indicated and true iso values for separate camera models, you can look it up. Usually the gap isn't huge, but is still present and is different for camera models. Dxo haven't tested X100s nor xt1, though.

Heh, yeah maybe you are right. I just tried to find the source again, but no dice. Maybe it was a late night read and I misread the camera's being tested
Edit: Found the source and indeed I either misread or misremembered the camera being tested - in this case the A7R. They judge the A7s to have about 3 stop advantage over the A7r.
I did find this article that states a similar thing ie happy with IQ at 6400 for the A7R II and 25600 for the A7s. But its well inside the subjective zone

Don't get me wrong though - the A7S is one heck of a great low light tool. However, I am finding that the A7RII is quite decent as well.

I had an a7ii and sold it in favor of the a7rii. I was actually disappointed in the a7ii noise levels. The a7rii is much better at higher iso. My d600 had used h better high iso performance as well.

If that were the case I would own the S. It's not from many examples and comparisons across Gore's inter =webs.

That is not what DXO finds if you look at their signal to noise ratio data. The A7rII is about a half stop better than the A7 II, and nowhere near a full stop.

To answer the OP's question the A7II has almost exactly the same high ISO noise performance and the 6D, so having both the 6D and the XT-1 you can pretty much know the difference between the A7 II and the XT-1--it will be the same as the difference between the 6D and XT-1.

I think one of the complicating factors is that it's not just the total amount of noise present, but the quality of that noise-- and how all of this is impacted by various types of processing.
This is particularly true when comparing Canon, Sony, and Fuji (old Sony+XT CFA) sensors and their in-built image processing chips.
It can be that the native output looks similar in terms of noise at, say, 6400, but one of those cameras will take much more processing than the other (or much more of a certain type of processing, like lifting shadows).
In this way online tests and hearing opinions can help, but it's not really great substitute for actually getting ahold of a bunch of RAW files (ideally ones you've shot, but those shot by others is a good substitute) and running them through your own processing workflow. When doing this, it's a good idea to keep in mind that you should be more adept at processing the files you've already been working with for years-- so you might want to give a small handicap to those systems you're totally new in processing.
