Lenses... Please help???

Hey Everyone, I am looking for 2nd hand lenses. I have the Pentax K100D with the standard 18-55mm and would like something bigger like 50-200mm or 150-300mm.

But I do not know what makes are compatible and where to find them?

Please help???

More Lenses?

Hello Dazza88, Welcome to the Forum!
Just about any lens made with a Pentax K, KA or KAF mount will work without a converter. That includes after-market lenses also, like Sigma or Tamron, as long as they have a K mount.
You can also use an "M42" screw-mount lens with a converter.
But the problem is, as the lenses get older, they support less features.
The newest series, the DA and DAL, support virtually everything the camera can do.
Going back (in time) the FA and F series were the last AF lenses made for film cameras, and work fine with digital cameras, but may lack a few functions of the latest lenses.
Going further back, the A series had an auto-aperture setting, but manual focus.
Before that were the K and M series, fully manual (aperture and focus).
I have simplified this breakdown, there are exceptions, but generally you can decide how many "Auto" functions you need and go from there.
If you look at the lens reviews on this Forum, you'll get some idea of the performance ratings of various lenses. For now, I'd suggest comparing Pentax 70-200mm, 50-200mm, etc and see what fits your needs.
Good Luck!
Ron

Wrong forum for this question.

All lenses found here are compatible:

Just be careful for the infamous Ricoh pin on some Ricoh and made for Ricoh lenses. But it can be easily modified.

The lens review sections here are a great resource for you. I spent lots of hours there reading as I was first buying lenses and I still return regularly to read about others experiences with lenses that I am thinking about or run across.

As for a compliment to your 18-55 the DAL 50-300 that Twitch mentioned is a great addition and is rated very well. They can often be had for very little in comparison to equivalent lenses and give you a great reach. If finances are tighter then the olderSMC Pentax-FA 100-300mm F4.7-5.8 tends to run about 1/2 what the newer DAL 55-300 costs and is also very highly rated for a superzoom. Just a word of caution - its silver

This is perhaps now the automatic response for the short answer.
Some people won't yet bother with the "why this lens?". "just tell me what to buy!"
And invariably our collective answer will be, " DA 55-300."

Funny. But 'tis true, ey?

To add to RioRico's good list:
Inexpensive brilliant MF zoom - Pentax A 70-210mm F/4.0 Manual focus but automatic aperture, and a "macro" (read close focus) function at 70mm.
