I started off searching for a reasonably priced 28/2.8 AiS and ended up finding a 28/2 AiS sitting unclaimed in the consignment cabinet at the local camera shop. With a price tag of $100 it was pretty irresistible. It could use a re-lube on the focusing threads but I have no complaint about it optically. Interestingly, I was attracted to this lens because I shoot a lot of closeups and this lens (like the 28/2.8 AiS) can get very close...so THIS is the first shot I produced. steeple by kevin dixey, on Flickr It's definitely sharp.
