So, did I just waste my money by buying a 5D II to replace my 7D for portraits and other shallow DoF photos? I expect:
1 stop improvement in ISO performance
shallower DoF
true FL
noticeably sharper images
greater facial detail, especially eyes.
more accurate colors
more dynamic range
What I don't expect
Wizardry and magic.
Are my expectations realistic?
I have used both crop bodies and FF bodies over the past 10 years...I cannot put my finger on exactly what makes a FF better - it just is in my opinion. In the same way, I cannot answer your specific questions, since it is nothing I can put my finger on. It is just a more "desirable" look, and that's the best word/description I can come up with for FF's advantage over crop.
Think of it this way. The crop camera obviously better than a point-and-shoot camera of course. Even an old 20D smokes any P+S on the market in my opinion. But in the same right, any crop SLR is like a luxury Honda. It is a luxury car compared to regular Hondas, but it is still a Honda. The FF camera is like a luxury Mercedes. So, if even a low end Mercedes is already nicer than a luxury Honda, imagine what the luxury Mercedes feels like. Like that, there is nothing specific I can tell you, other than maybe you should try renting a 5D(I or II) for a day and testing it against the same identical shots from your crop body, side by side shooting on tripods or whatever (same lenses, same manual settings); then compare them in a dark room on a big monitor.
-edit-
Oh! I did think of one thing that makes FF much better than crop. Ideally we all want to shoot our photos with the right settings on site, and edit as little as possible - well, in the real world, esepcially in event photography, the need arises to edit photos in post more than we might want to at times. When editing sliders on different effects and filters on a crop body image, I can only move the sliders about 10-20% of the way left/right before I have to stop and it begins making the photo look bad. When editing FF images, I get much more leeway with the filters, effects and plugins in Photoshop. I can bump the brightness up two or three times what I can on a similarly shot crop image, without making it look bad. That is probably what stands out the most when in post...I do not have to take weird steps to get my photo to look good - I can just do what I want without adding damaging side effects to the image.
