For any current or former 1D3 users...
I just picked up a used 1D3 body. Note this is my first 1-series body.
Is it me or do the AF points in the viewfinder fade a bit unless you are looking ON DEAD CENTER through the viewfinder? Compared to other EOS cameras, it seems to need more 'directional' viewing. I have used 20D, 40D, 5D II, 5DIII.
Also, seems that its harder to see the entire contents of the viewfinder like the exposure meter on the right side while wearing my glasses than with the other EOS cameras I have used. If I take my glasses off and wear contact lenses, I can see it much better. First time I must say that I can't see the entire perimeter of a viewfinder.
