Same sensor. Very little difference in performance. Plus, if you could afford a 7D, you should spare a little cash as used 5D mark II's tend to be very lowly priced nowadays.
Right now you can pick up a refurbished T4i for $515 direct from Canon. If you need more power, the 7D can be had for $1074.
I always hear about the poor low light performance of the 7D, how does it compare to the 60D/rebel line low light capabilities.
yeah well.. if someone wants a 7D he will maybe not be happy with a 5D MK2.
you know the 5D MK2 is not exactly a sports camera or famous for it´s great AF system or speed.
but for the OT, as a travel camera, the 5D MK2 will be a nice camera.
thought i would not buy one new.
the price difference between the 6D and the 5D MK2 is non-existent here.
having both, i can say the 6D is the better camera.
we can argue how much
of an improvement the 6D is.
canon could sure have implemented a better AF in the 6D... but it is an improvement (except for x-sync and shutter speed).
so for the same price (~80 euro difference here) i would always buy the 6D.
i don´t think the 70D will be out before august.
there is just a cashback action starting in germany for the 60D that will last a month.
so it´s unlikely canon will release a 70D anytime soon.
