Recommended lens(es) for K20d

I'm planning on getting a K20d fairly soon and would be intersted in opinions on lenses to go with it. I have inherited a 55/1.8 super Takumar lens from an old Spotmatic, plus a 135/3.5Hanimex . I was thinking of something like a 18-55 zoom. I am expecting to stick with Pentax for a long time so would like to build a good system from the start. Any thoughts greatly appreciated.

The 18-55 kit lens is decent but if money is no object, go for the Pentax *DA 16-50f/2.8.

If that is too expensive, Sigma and Tamron make an 18-50 f/2.8 and 17-50 f/2.8 repectively. Both are good zooms and cosiderably less expensive.

Last but not least, is the Pentax DA 16-45 f/4. It is not as fast nor as long zoom wise, as the three metioned above, but is an excellent lens nonetheless and easier on the pocketbook .

Welcome to the forum!

Welcome bessa. Let me preface the following with I am no god of ground glass and only presenting options.

The current Pentax lineup looks like this:
+ The DA18-55 AL (or AL II) kit lens. It's no slouch. Possibly the best quality "kit" lens in the industry. That's your least expensive option.
+ Next up in price would be the DA 16-45mm f/4.0 which I have not owned but have used and/or handled raw files from to say it renders very nicely.
+ Next comes the DA 17-70 f/4.0. I can not attest to its virtues but haven't seen a lynch mob coming after its designers either. It will run you around $500 and provides you with SDM (silent focus motor) and a bit more range.
+ The DA 18-250mm f/3.5-6.3. This is a "super-zoom" or "utility zoom". It has massive range, and very good image quality if you take into account its inherent limitations. I had a copy and loved it - actually somewhat regret letting it go. There is some barrel distortion at the long end and some light vignetting at the wide end. But it is a great lens nonetheless.
+ Finally is the DA* 16-50mm 2.8. This is the top-of-the-line short zoom. Better optics, it's fast (f/2.8), SDM AF motor and weather sealed. It comes with a matching sticker price.

For 3rd party offerings there are, for me, two hands down best choices:
Tamron 17-50mm f/2.8 & Tamron 28-75mm f/2.8. I own the Tamron 17-50 and in my opinion as far as image rendering is concerned it's as good as the DA*16-50 and about $300 less expensive. I am finding for my day-to-day shooting I run up against that 50mm mark too often with both my 17-50 and DA*50-135 and am planning to "fix that problem" by adding the Tamron 28-75/2.8 to my bag.

So there are a bunch of options. I'm not going to attempt to sell you one way or the other - they are all good lenses in their own respects. But... keep that old glass too!

Get the kit lens (DA 18-55mm). It is a good lens at great price. If I were to do it all again, I would then go straight to the DA21 Limited, DA40 Limited and DA70 Limited. I don't have the DA40, FA50 instead, but the other 2 are so good that I will get the DA40 at some point.
A little more about your shooting style would help with suggestions. Once I started again with prime lenses, I almost never have a zoom on my camera.

The Tak will be a great lens for you but no auto focus and you'll need a M42adapter(buy the real deal Pentax!). You'll also have to learn to work with stop down metering.My opinion for whatever it's worth is to take a short step up price wise from the 18-55 and get a DA 16-45 which will allow you to use all the auto features of the camera while you are getting used to it. Later you can expand your horizons.

G'day mate.
Suggestions so far are good - agree with them all.

Travel & landscapes - 16-45 or 16-50 are great - anything wider (esp. for buildings/architecture) requires something like a 12-24 or Sigma 10-20.

Kids - something fast, like an FA 50/1.4 (just 'cause it's AF) or if you have the funds, the 50-135 (your kids are worth it! - just a subtle plug for Pentax!). Though the newer 50-150 offering by Sigma would probably match the 50-135 (don't know about its price though).

Best of luck with the Mrs on getting this expensive glassware! (call it china for a better reaction)

When you want to go wide, the 12-24 is very handy.

A decent tele zoom to consider is the DA 55-300. Also don't pension off the M42 mount lenses and get a genuine Pentax adapter for them. The 55mm f1.8 used manually will provide rather pleasing results.
