Currently I have a T3i. My favorite subject is birds in flight, particularly ospreys. My most often used lens is my 400 5.6 L prime. I have enjoyed the T3i but plan to upgrade to a 7d or 70d by Christmas.
No interest in FF since I seem to always wish I had a longer lens even with the 400 L 5.6. Almost never shoot video.
Main reason to upgrade is that I am starting to notice the limitations of the pentamirror viewfinder and 9 point AF of the T3i.
1) Does anyone here have real world experience with both the 7d & 70d viewfinders ? On paper the specs look very similar with perhaps a very small size advantage for the 7d.
2) can anyone share their BIF AF experience with both cameras?
i like the metal 7d body. I bought my first SLR in 1972 so I remember and appreciate that style body but still I would take a polymer body if it meant better performance.
For me the 7d vs 70d question then comes down go the viewfinder and AF. Any comments appreciated.
