I have a nice clean copy of the Minolta 70-210 f/4 zoom. I found this copy last year and paid $300+ for it which is well above "market." It was worth it because it is a nice clean copy with excellent image quality, smooth zoom, smooth AF, clean glass, and only light scuffing on the lens body from normal use.
I've been very pleased with this lens on my A900, but have recently purchased the Sony 70-200 f/2.8 and this lens is now redundant.
$180.00 shipped CONUS - price reduced to better reflect market (No international shipping, please.)
