Any pentax lens made in the last 50+ years will fit. If you're OK with manual settings, you can sometimes get fantastic prices on really good optics at pawn shops. I've gotten a few for my wife's k-x, and couldn't be happier with them.

Get the SMC-F 50mm f1.7. It's slightly sharper and cheaper than the f1.4, but a half-stop slower. It's autofocus too! You can get it in F and FA style (FA just looks newer, both are optically identical and both have autofocus). The 50mm f1.7 is my all-time favorite lens, followed by the 100mm f3.5 macro. If you can't find the 1.7 or really want the extra speed, get the 1.4. But the 1.7 is sharper up to about f2.8, where the two lenses equalize.

If you want a fast zoom, I recommend the Tamron 28-75mm f2.8. It's constant aperture, which is really nice. But it's a heavy, heavy lens, and there are some quality control issues with front/back focusing. So buy from a reputable dealer, as you may need to send it back to get a good one.

The 50mm f1.8 is a new lens, and I don't have a lot of info on it. It's reasonably priced though, which will drive down the eBay cost of the older autofocus fast 50s.

Not a farewell, just a forced redirect.

It's true, Local.Woot is no longer, but please don't despair.

Never-ending savings are still to be found on Deals.Woot each and every day, so come on in. Don't think of it as a time for tears. Think of it as a way to bring us all closer together under one roof.

Sorry

This is only for people who have bought woots

We restrict voting to users who have purchased something from one of the other Woot stores. It's not just because we want your money (which we do) - it's the best way to be sure all the votes are coming from real people and not spam-bots or phony accounts. The best way we can think of, anyway. For now.

You can always get voting rights by buying something from one of Woot's other sites:

Purchases through Deals.Woot don't count, because in that case you're not buying anything from us. And we don't have your account information for those purchases.

If you think you've bought something from Woot before and still can't vote, make sure you're logged in with the same account you used to buy from us.

Geez, why so negative?

You have to vote up more before you can vote down.

Don't get us wrong. Negativity has its place. And downvotes are just as essential as upvotes when it comes to making Deals.Woot a useful place to find deals.

But when your votes lean so heavily toward the dark side, we have to wonder. Go vote up a few things. Accentuate the positive for a little while. It'll do you some good, and it'll do the site some good, too. Then you can get back to dealing out the smackdowns, OK?

Too late, we all heard you!

Hmm... you're wanting to take your vote back?

Well, that's a bit tricky. See, we do a lot of stuff with your vote, using it to work out the popularity of what you voted for, compare that to all the other things voted on, tally up our leaderboard, work out your reputation. Someday we'll do a little cartoon showing just how hard your vote is working.

Anyway, taking votes back messes all that up, so we give you five minutes, in case you just mis-clicked. After that we've got to say no take-backs. Luckily, votes are free, so feel free to throw them around left and right wherever you see fit.
