Got to love the 50mm F1.7 minolta prime. That and the 28mm F2.0 are the only 2 lenses i need. How do you find the autofocus on the A300? I have the A450 and i have to watch it like a hawk as it seems to love focusing on anything with a straight edge. It's a royal PITA if i have a subject set forward of something like a wall.
