SMC Pentax-F lenses

macman44 · 12-12-2011, 09:02 PM

I have a couple of these lenses from my film camera days, and wondered if they are still useful in today's environment. One is a Pentax 35-105 zoom f:4/5.6, and the other is a Pentax-mount Sigma 70-210 zoom f:4/5.6. Both autofocus. What kind of user would be interested, and what would they likely be used with?

If they have any value, I can post them in the Marketplace. What sort of price could I expect, if anything?

I also have a Pentax SF1 film SLR, but I doubt that anybody would want that . . . . .

Thanks.

F lenses work just like DA lenses as far as exposure and autofocus goes; they are fully automatic lenses so you can use them with any DSLR without restrictions. I doubt you'll get much for those two, but you can definitely try listing them if you don't plan on using them yourself.

Average price for the 35-105 is about $75.

I use a F35-70 3.5/4.5 as my walkabout lens, when I use AF ( I'm a manual focus man

) and it's a very nice lens, I rate it as better than the DA 18-55 kit lens that came with my K10.
At a camera fair here in the UK a few weeks ago any F Series lens was fetching good money, people like them.

Likely the e35-105 no more than $130 (the highest that has been paid here based on reviews) but Adam is right $75 is more likely
the 70-200 Sigma is likely to be in the $50 range
the SF1would probably bring in 30-50 if it's in good working order (it's actually a very good camera)
Or put up the lot for $150

Thanks for all of that. It's good to know that it might be useful to someone.
