WARNING - the older long tele lenses tend to have much higher CA Than older short fl lenses and its really noticable on APS format DSLR Cameras. If your going to go with older glass be careful. I would Think later designs from the mid 80's or later with low dispersion Glass or true APO will work better over 200mm than the 60's and 70's glass in general. If you use primes and don't mind doing CA Corrections, than you should be able to get good results with the Old OEM lenses but if you don't wanna do CA corrections than your Gonna need really good teles. jco

Subject: Big-telephoto advice We bought a waterfront cottage last year and all of a sudden I'm interested in wildlife & maritime photography. My biggest lens is an old old OLD Tamron 70-210 and its contacts are problematic, the camera can only see it half the time. This would see very limited use, probably just the cottage, so I was thinking maybe a used big old fixed-focal-length telephoto like my Dad used to use 30 years ago. I went poking around on EBay and sure enough, there are big old lenses for sale there regularly. For my K20, are there any classics that I should particularly lean toward or turkeys to stay away from? I'm assuming nearly anything will fit, e.g. the "SMC Pentax 500mm F4.5 4.5/500 Telephoto" with the bidding currently at around $700 Canadian.
