I purchased a 28-135 minolta lens from Henry's, since the ones I've tried had a little 'grind' during zoom, and they didn't mention that the one they were selling had one.
I received the lens and yes it had the 'grind', which made me think maybe all of these lenses have it. I asked to return it, and they were very nice and polite about it, refunded my full cost and shipping BOTH ways, without even asking a copy of the receipt (of course the amount was on the shipped box itself).
You can see when a company is good when they have to deal with returns, and especially when they have to pick up the tab. Henry's were ABSOLUTELY OUTSTANDING, the best service and treatment I've received from any online seller when I had a problem (B&H comes close).
Kudos to Henry's!
