Originally posted by Peter Zack I have bought few of those "lots"...This is my dad's gear and know little about it etc. Generally these are sellers that are trying to offload gear that is defective and hide behind ignorance. Some genuinely don't know. I once bought an f70-210, F 50mmf1.7, F28 f2.8 and an SF1. The seller said she was selling it for her mother and the description was something like "mom used to be a pro shooter and has since switched to a digital. She no longer needs the gear and it has been safely stored for 2 years." I asked several questions and got a bunch of vague answers but decided to take the risk...
I bought a camera bag full of lenses from a nice lady that said it was her Dad's equipment, and he passed away. At the time I checked her recent sales - and it was all household junk and toys, so that checked out. The first buyer backed out, so through ebay I bought for my original bid. For around $80 I go a nice pentax-f 35-70mm 3.5-4.5 (this is my walk around lens, just got some shots an hour ago), Tokina f/2.8 135mm manual prime, Takumar 70-210mm with auto focus (I know - inferior to the Pentax version - tested it but haven't used it since). Also lots of filters, some magnification filters that I haven't played with yet, a 2x adapter, and a Pentax film body. When I got home last night I re-inspected all of the lenses for fungus - all clear! All the stuff was well cared for. Better than my old film gear in the back of my closet!
I was originally going to sell most of the stuff, but except for the 70-210, everything are keepers. The Tokina 135mm f/2.8 is a sweet lens, and the Pentax-f 35-70mm shoots like a prime for the entire (limited) range - even at 35mm f/3.5. So I got a good deal - this time. What scares me is buying a newer lens from ebay - Sigma 17-70mm for example, that may be a bad copy or other lenses known to have back focusing issues. For newer lenses I'll buy new and under warranty except from people that you know and trust (KEH and frequent posters to Pentaxforums, etc.
