Must be a Nikon D800/E; and I am a Canon user. Ability to use both FX and Dx lenses on the same camera is hard to beat. I wish Canon would consider this small convenience in the next model of 5D. Currently I cling to original 5D for landscapes and 7D for birding. One body that can introduce a crop when needed is a dream. Probably is going to stay a dream in Canon world.
What about D800, is there internal dust accumulation as well or not?
Canon should have "slightly" revised 7D with full frame sensor and GPS. One convenient feature that, in my humbly opinion is missing, on all full frame Canons and available on Nikon is ability to switch on crop factor. One camera can be used for landscaping and birding by a switch. I have 5D original, 7D, and a few L lenses otherwise I would consider Nikon 800 serious. Actually I am staying for now with what I have. Anyway, it is a person behind the camera that produces a picture and camera is merely a tool.
I am yet to see a Pro who is using NEX system. I am not sure if it is possible to produce a high quality work without good optical viewfinder. NEX in my humble opinion is a good pocket camera to carry around, but Iphone, if is not a match yet, but will be pretty soon. It is very difficult to compare a DSLR with multitude of lenses and a handy pocket camera. They are intended for different markets I guess.
Well it looks good, but for know I will stick with my original 5D and for bird photo with 7D.
I have original 5D and 7D and considered upgrading for 5D M3, but may sell both to go Nikon D800. I would probably keep 24-105 L as I like this lens as I can use an adopter. I care less about 36 MP as rarely print larger than 13" by 19" and 12.8 MP on my 5D is more than adequate, but ability to use full frame for landscape and crop for birding in one camera may be a factor for me. Moreover, the price, I believe, is reasonable for D800 unlike canon 5D M3. I am not sure yet but will see.
There is Corel PaintShop Pro X4 for $39 and it has most features of PS5
