Upresing isnt allowed for stock. that would be unfair for the customer (they can do that themselfs) and iStock notices that.
I dont have to buy new glas, i bought mine for FF because i knew that i was going to upgrade.
We all know that the AF is better than the 6D, just look at the specs. We all know that Nikon is on 180nm and Canon on 500nm so they have better high iso.
Not gonna switch, i love my Canon ergonomics and i have spent a bit in glass
@Marsu i´d say you cannot start out and not be broke
