Thank you. In the interest of keeping things above board, I've re-uploaded the file with the metadata embedded as you desired sir!I'll be rushing out immediately to pick up a new 7D MK II. What all the hub-bub is about regarding the original 7D is that the complete lack of any high ISO usage, renders images useless and totally unusable for any purpose, as this sample taken at ISO 3200 on my original 7D, clearly shows... 7D MK II please get here soon!
EF 100-400mm f/4.5-5.6mm L IS USM
Good photo (love the colors), but I would say there are some issues with it that are definitely due to the camera and lens combination. There is also no embedded metadata, so there really isn't any way for any of us to verify that it really was shot at ISO 3200.
I've taken a lot of bird photos at ISO 3200 on the 7D (mostly with the 100-400mm lens), and the noise is usually a lot worse than that. Assuming you have not applied any NR, there is definitely a loss of fidelity. There is also a loss of detail. The 100-400mm lens imposes increased softness at f/6.3, and even more at f/5.6...usually, f/7.1 is the sharpest aperture (as f/8 is beyond the DLA of the 7D sensor and just barely a touch softer). Having used both the 100-400 as well as the 300 & 500 Mark II lenses on my 7D recently, I can attest to the fact that at that magnification/crop, even at ISO 3200, the lens is definitely costing you some sharpness and detail definition there...even though they are noisy, a shot taken the 300 or 500 w/ 1.4x TC at f/6.3 usually has much sharper detail.
I'd also point out that the full-size download shows a fair amount of posterization in the background, which is another one of the issues you encounter when using higher ISO settings with small pixels. Gain is so high for such a low full well capacity that you get a lot more quantization error than with something like the 5D III or 1D X and their significantly higher full well capacities.
I agree that there is certainly some posteriztion in the background and it is certainly far from perfect, I would edit exposure and some other things as well. That being said, it is not a crop, it's the actual size of that particular image. I have other bird and wildlife images at high iso's with my 7d as well and some that are really quite usable. Most with my 70-200mm f/2.8L IS II. It is much more challenging with the 100-400 as you pointed out.
I'm certainly not cheering the 7D and it's high ISO capabilities, just that for all the complaints about it, decent, usable images can be had at what is considered a high iso for that camera. My complaint with it is with regard to high iso and portrait work, there it has given me some challenges...
I love my 7d, I love my 5D MK III even more, not at first though... I will be a candidate for the 7D MK II, most likely within the year after it is available... My 7D will be passed down or sold sometime in that future... I must say, it's served me well for the over 50,000 images I've taken with it so far!
