Mine did, and that's the truth. Got grainy very quickly.

Noise and control of such is very dependent on the raw processor of choice. DPP will always produce a better result than a basic LR adjustment upon import, for example.

ISO 16000 gets a bit sketchy on the 7D2 though, just miss the exposure and it is hard to recover it.

QUOTED IMAGE

I think we're saying similar things. If you can expose properly and maintain a high enough shutter speed to get the results you want, the 7D2 is fine at high ISO.

If the shots are underexposed by a stop or more it goes downhill quickly. The dimly lit pubs and halls I tend to shoot in are kryptonite to my 7D2. There's just not enough light to support a 2.8 zoom, 1/500 (too slow) at ISO 12800. At 16k+ the files are not pleasant to work with at all.

Processing is definitely a part of it, and LR isn't ideal. Maybe the trick is to put effort into better processing, using third party actions, plugins, etc.

I am puzzled by statements of 7DII needing 'really good light'. This shot in the dark underspace of my house

QUOTED IMAGE

-3EV ambient lgiht, the lowest level at which you can AF and meter, which I was testing

I had to stand there in 'the dark' for about 10-15 min. simply for my eyes to acclimate enough to allow me to even see where I was aimed for focus!

What are the parameters for this shot?

The 7D2 has no problem with long exposures from what I've seen. It's good for astrophotography in bulb for 120 sec for example. The scenario I'm thinking of is marginal light, high shutter speed, ISO 6400+ where the constantly changing stage illumination guarantees some underexposed and many borderline shots. Ceili night at the neighborhood pub where you want to the shoot the dancers not the slow moving (yet decidedly wobbly) patrons with a 2.8 zoom and no flash kinda thing.

The ISO was 12800, metered as EV -3 by my handheld meter. Shot at f/2.8, this reading would result in 64 sec. exposure.

It is more about exposure than level of light. Every camera is going to produce noise if exposure is to the left and you are at a high ISO and then bring up the exposure digitally (even though extended ISO at least past 12800 on the 7D2 is digital anyways). This happens especially with colored lighting that changes rapidly, so you don't get a full spectrum, always a recipe for noise. In other words, in situations with more light, but faster shutter speeds needed like indoor sports, especially school events, these situations pose the same issues. Artificial cycling lights, 1/1000th or faster, high ISO, and f2.8 are often not enough, and isn't very different from stage or bar scenes when it comes to exposure results and noise.

If you cannot use flash, to improve the situation, then you are left with good post processing tools, and technique, the digital darkroom is just as important as the shot itself in many cases. I wrote up this thread that might provide some insight into different ways to manage the 7D2.

You are going to hit limits and have to accept them, I feel. Some cameras will get you a bit closer, maybe a stop or so less noise overall, but that only takes you so far as well.

Thanks Teamspeed for the tutorial. I had gone through your posts on exposure before but will use them again when I get my 7dII. Thanks for sharing the detailed process!

Quick example of a low light artificial light using our cat (as my kids are tired of being photographed). This is at ISO 16000 on the 7D2, with a before and after post processing result.

UNDEREXPOSURE with later attempts to brighten with postprocessing (such as increases to Exposure parameter of RAW files or to Shadows parameter) will result in more 'noise' with evident 'banding' of said noise in all but the most recent Canons...the 5DIV was the first Canon to get over the banding of noise.

Actually lack of banding when digitally pushing the exposure 1 or 2 stops hasn't been an issue since the 6D, 7D2, 80D, etc. Perhaps going 3 or more might show some, but even I haven't seen that myself.

Tique, you will love the 7DII and it is an improvement and you can get great pictures at high ISO if you don't need to blow it up. past 8x10 or so.
Great camera.

I have a 7D and the 7D2... IMO, the 7D is a good camera but, the 7D2 outshines it in every respect!

7D2

But the 7D is not shabby a bit...

I had my new 7DII at our local zoo Thursday and really enjoyed learning the differences from the 7D. The "autofocus" is amazing. I do miss the meter the 7D had at the bottom of the viewfinder though! I wish Canon had left it there!

Is there a firmware update or download to put the meter in the bottom of the viewfinder on the 7DII?
