3. Thinking of moving objects(my daughter), I set my camera to AI SERVO, used all AF points, turned off IS and snapped away. How would the focus on the 6D compare to this type of situation? I would hope it would be better? BTW, this was manually pressing the shutter button, not using burst.
The 7D will be better, IMO. Higher density of AF points and all cross-type AF points both mean better AI Servo performance.
5. Is using LR to clean up noise an acceptable practice? Does anybody really care if they like the picture? Most people that look at my photos(all but one really) don't even notice things like bad shadows, noise, sharpness, etc..
7. Again, the sharpness in my images are also improved in LR. And again, I ask, is it acceptable practice to use PP for things like this?
Of course. All's fair in love, war, and post-processing. Well, almost all - some photography contests restrict the amount/type of PP you can do, but NR is pretty much always fine.
6. As for the "advantage" of a crop sensor. Don't take my words too seriously I just meant that I get 1.6x vs. FF. Call that a pro, con, whatever. If I take a picture at 200mm with a 7D vs. FF, am I really getting a "closer" picture?
You're not getting a closer picture. A 200mm lens projects a subject on the focal plane at a given size, regardless of the sensor. But as pointed out, current APS-C sensors generally have a higher pixel density than current FF sensors - that means more pixels on target with APS-C. Whether that's a benefit for you depends on your output. Comparing a 7D image to a 6D image cropped to the field of view of an APS-C sensor, the image quality will be at least equivalent, the 6D may be slightly better...but it will be a 7.8 MP image vs. an 18 MP image. 8 MP is sufficient for web, prints up to about 12x18", etc. If you don't need to crop the image, the 6D will offer substantially better IQ.
9. I noticed someone mention the 6D will easily beat out the 7D in low light. Thinking about that, I like to take pictures without flash whenever I can. I like the natural lighting better. I think the 6D is much better for this scenario.
10. Someone mentioned the noise when taking bird photos. I agree 100%, the noise is really noticeable. If you look at bird pics on 500px, flikr, etc... they are so clean, I often wonder if I'm missing something. I hate to say it, but I'm pretty anal about noise.
The 6D (any FF sensor) gathers more total light - that means less noise at high ISO. I think my 1D X is about 2 stops better than my 7D, the 6D is likely at least 1.5 stops better. Combined with a faster lens, that can make a big difference (provided you have enough DoF).
Of course, tomorrow I might change my mind and want to buy the 5D3 I'm sure you all know how that goes
As a general purpose camera, I think the 5DIII is a much better choice than the 6D. I believe that you'll find the 7D to 6D to be a step up in image quality, but step down in AF performance for moving subjects and in build quality. A 5DIII would be a step up across the board.
