I have jumped into the big photography pond, and am way over my head is there help? I first bought a Sony a300 camera & adaptor to accept my old Minolta manual lenses. Didn't have the know how to use them with the a300. took advice, and bought three auto focus lenses, to use with the a300, a Minolta Maxxum AF 50mm 1: 1.7 (22), a Minolta AF Zoom 35-70mm 1: 3.5 (22)-4.5, and a Minolta AF Zoom 75-300mm 1:45 (32) - 5.6 AF Zoom 1:5m/4.9ft. Macro. Don't have the know how to use them ether. Bought the Gary L. Friedman manual for A. 300 & 350, Not knowledgeable enough to use the manual. Tried to download owners manuals for the use of the lenses, but, could not. I did all this to try to get better photographs of close ups of items using my old Sony DSC-V3. At 83years old I have managed to get in way over my head. Any suggestions other than to dump all this new equipment, and go back to the DSC-3?
