In looking for my first legacy lens (for my E-PL2), and specifically wanting a tele prime, I was recently offered a Minolta 300mm 4.5 IN CM MC tele Rokkor HF (72) lens. Having not even seen it yet, it sounds like it might be freakishly large for my little m4/3rds camera, causing it to be difficult to hold, and too unbalanced for tripod use. Is this true? But if not, just how good of a lens (sharpness and color) is this lens? Any other comments would be appreciated as well. Thanks.
