Lens, reason enough?
I know this is similar to many others' questions, but my particular twist is that I have no idea what the values of the lenses I have are. Back in college, I was given a hand-me down Pentax with some lenses to go with it. By the time I made it through college though, the camera body and the main workhouse lens had been stolen.
After looking at the prices of lenses and the advice about keeping lenses when possible, I dug up the camera case and old lenses. I've got four left, and they aren't clearly marked for a novice to just report the numbers and models you probably want, so here's the markings I do see:
1) SMC Pentax-M 50mm looks like f22-f1.7
2) A TAMARON converter labeled, "Tele Converter 2x For Pentax-K"
3) One labeled "Auto SEARS MUTLICOATED 28mm" model No 830702966 looks like f22 - f2.8
4) Finally, the big one, Albinar-ADG 77-300mm f32-f5.6
The old camera body, according to the book in the case was a Pentax ME Super. So now the same generic questions apply, will these lenses work with a basic level Pentax dSLR (I'm assuming all I can afford would be a K100D)? If they would, would they be worth getting a Pentax over a Nikon D40, assuming I won't be able to afford any additional lenses for a real long time?
If they do work, will there likely be any trade offs besides manually focusing?
Thanks for any and all advice!
