Hey friends.....hope everyone has had a nice Sunday thus far.
I'm quite frustrated and it's the same old story we've heard so often with regard to crop censor cameras in low or dim light. I'm in the woods a lot shooting wildlife and birds and my Canon 7D Mark ll and 100-400 ll just drives me crazy having to keep bumping the ISO to get a correct exposure. Virtually it's almost useless. I know it's been said an image with noise is better than no image at all but I'm not sure I go along with that. If I can't use the photo what's the point? Please don't address that at this time. It's a great setup in good light. I love the 10 frames per sec and the lens is amazing but I wonder how I would like a FF with the lens knowing I'm losing reach. Also what would be a good Canon FF that will shoot 10 fps? I can't afford the 1D so let's take that off the table up front.
Looking forward to your educated responses.
Thanks ~ Danny
So the questions

Seriously?
I took nearly 8000 images yesterday with a pair of 7DIIs... mostly at ISO 5000 or 6400.
In fact, I've used the cameras as high as ISO 16000 with usable results. Here's a 7DII test shot done at 16000 (1/125, EF 100-400II at 158mm, f/5):
Sure, there's some noise in that image.... But it's so well controlled a very nice 8x12 or even 13x19" or larger print can be made from the image.
Short of the 1DXII, in addition to the slower frame rate you've noted, none of the FF Canon are going to gain you more than maybe one or two stops higher usable ISO, you'll lose a lot of the "reach" of your longest telephotos and won't be able to use about 25% of the available Canon lenses (and a lot of third party lenses). You'll also have a slower 1/200 or 1/160 flash sync with full frame, compared to 1/250 with the 7DII. If you ever use flash, that might be important. And, full frame cameras are sometimes noisier, due to the larger mirror and shutter (my 5D Mark II has caused horses to "go vertical" a lot more often than any of my APS-C cameras).
In fact, flash may be a partial answer... Often wildlife ignore it as if it's a distant lightning flash or glint of the sun off water or glass. But flash does slow down your shooting.... Unless you spend a small fortune on highly specialized strobes, you get no more than 2 or 3 shots in a burst before a flash needs to pause and recycle, even with a supplementary power supply. And after some 50 or 100 shots in fairly quick succession, the flash is likely to shut down for fifteen minutes or half an hour, to prevent overheating.
A couple things that can help with high ISO shooting are to shoot RAW and be
very careful to avoid underexposure, then post-process with some noise reduction applied (I like and use Imagenomic Noiseware as a plug-in to Photoshop... it's also available as a stand-alone program). Above shot of my cat was shot that way, but
did not get any extra noise reduction... Just the default NR settings in Lightroom.
The other very common "problem" is often how people view and evaluate their images. While it can be necessary and useful to enlarge an image to "100%" or more on your computer monitor for retouching... that's ridiculously large magnification to evaluate image qualities such as noise, resolution and focus accuracy. With a 20MP camera, that's roughly equivalent to making a FIVE FOOT WIDE print and viewing it from 18 or 20" away. OF COURSE it looks like crap! Back off and evaluate these things at a more reasonable size... more like the actual, final size the image will be used. A 16x24" print is "40%". Heck, even 20x30" is only 50%. A digital display of any image is likely a whole lot smaller than those. The fact is that YOU are likely the only person who will ever see your images at ridiculously large magnifications, since other people only see the finished results.
Of course, if you crop images a lot, that can be another factor. Cropping a full frame image down to APS-C dimensions is essentially "throwing away" nearly 60% of the camera's available resolutions. So do all you can to "fill your viewfinder" with your subjects, to keep cropping to a minimum.
Stop your whining! Back in the days of film we shot wildlife images with Velvia 50 and Ektachrome 100 VS. The fastest slide film I used was ISO 200. Today, using 7DII I rarely use any lower than ISO 400 and those cameras have "cleaner" images than ISO 200 slide film, at ISO 6400 or even higher! That's at least 5 or 6 stops "faster"... 32X to 64X greater sensitivity than E200! 128X or 256X more sensitive than Velvia!
The other solution... faster lenses. Same as you, I use and really like the 100-400 II. However, in some of the more extreme low light situations I need to shoot, I know it's f/5.6 is just not adequate so I switch to f/4 or f/2.8 lenses. In fact, I did that yesterday, using Canon 70-200/4 on one camera and 300/4 on the other, most of the day. I needed 1/320 minimum (and preferably faster) to shoot an equestrian event... fast moving subjects... in a covered arena that's probably darker than your "woods".
P.S. A 1Ds Mark III will do you no good what-so-ever.... It's ISO range is 100-1600, expandable to 50 and 3200. In fact, my Canon 5D Mark II uses the same 21MP sensor as 1DsII, but the 5DII has ISO range of 100-6400, expandable to 50, 12800 and 25600. The 5DII can shoot continously at about 4 frames per second... the 1DsII isn't much faster: 5 FPS. 5DII also has a better LCD monitor and video capabilities. It just lacks the autofocus system of the 1Ds-series (which is essentially the same 45-point system as in my EOS-3 film cameras).
5DII at ISO 6400, 1/200 (EF 135mm f/2L at f/2):
5DII at ISO 6400, 1/30 (EF 20mm f/2.8 at f/11):
I tried to keep my 5DII to ISO 12800 at the highest, but preferred to use 6400 or lower. I'll be updating to 5DIV in the not-too-distant future and expect it will be usable to ISO 25600 or 32000, though of course I'll keep to lower ISO as much as possible. 5DIV can do 7 FPS continuous shooting... up from the 6 FPS of the 5DIII.
