Thanks rs for the link. I'm confused because I've been on that site and wasn't able to sellect the 60D for the 70-200 2.8 IS II for some reason. Don't know if it was due to a bad connection that night or what, but was only able to find a few EF lenses that had the 60D option.
Any way, very informative and it makes me want the 5DIII even more now. I've always been blown away by the sharpness of the 70-200 on the 7D and can't believe that it can be that much better! I love it so much I'd say it slots in at number 6 - right behind my wife and 4 kids! Some days it gets a little higher up the list
I really enjoy night time photography - long exposure and hand held - so that is the real motive of the body upgrade. I also crave extreme clarity in the architectural details of the buildings I shoot in my travels with work. I understand that the long range shots on the lake won't be great by many standards, using the gear I have, but I just wanted to be sure there was an economical (relative I know) sollution to use with FF body that wouldn't be a down grade to my current "long lens" arrangement.
Thanks to the great responses here, I am comfortable with my plan of going FF. Now I just need a little more price drop and a good sale on top of that and I should be able to make my wife comfortable with the plan too! Luckily the 7D is a fine body (except for ISO) and I know the 5DIII will last me many years, so I don't mind waiting a while for the price.
I've been reading this forum for quite a while, but never posted a question before. Thanks so much to everyone that took the time. All the responses were helpful.
