Suggestions for some lenses for my new K-x?

I'm going to have the kit, which is an excellent lens, and a few hundred or so to possibly buy some other lenses. I want a telephoto, that's for sure, but I'm not sure if I should just get the DA 50-200mm for now and save some money or just go out for the DA 55-300mm. Any other suggestions would be nice too, I need a 50mm prime (suggestions there, AF or MF?) but not really a wide angle, and maybe a midrange to go with it. Oh, and I know the DA 50-200mm isn't the best zoom, but it is lightweight and easy to carry around, which I really like. The DA 55-300mm is much better overall, but it looks a lot bigger, and I've never actually used one of them either too.

Since you already know relatively well the Pentax-mount lenses, let me throw some 'wild' suggestions:

-a zoom: why not an all-around lens like the DA18-250mm ?

-a fast prime: 50mm is a nice range and there are plenty of nice lense fom Pentax A 50mm to Carl Zeiss 50mm f1.4....

- a pancake like the DA40mm to carry the K-x and lens in your jacket pocket..

Anyway, food for thought ...

Omg thank you I totally forgot about the DA 40mm. No matter what I'm getting that.

Definitely DA40 on the K-x ... so compact ... perfect street shooting setup for sure.

18-250 is not a bad idea either ... especially if you don't want to change lenses ... and I have seen some really good images from them as well ... they aren't a bad choiec for a super-zoom really.

Nice pair with a K-x. The camera's exceptional high ISO performance makes up for the DA 40's not-so-fast aperture and the lens correction feature negates the supezoom's distortion at the wide end.

This has become my secondary kit; DA 18-250mm and DA 40mm Ltd. The superzoom is comparable in performance to the 18-55 DA L + 50-200mm. The extra cost buys you the convenience of fewer lens changes. And a tiny 40mm mounted on a K-x is just delicious.

I don't miss the larger aperture much because the DA40 is sharp at 2.8.

I use these two lenses on my K-x quite often, with the pancake getting slightly more attention.

Yes it is. In low light I use f/2 on the FA 35 with the K20D; it's also sharp. With a 2.8 aperture lens on the K20D, I miss that last stop. The K-x gets me the last stop back with its high ISO performance, and the size of the DA 40 is ideal, so I like that combo too.

Ok so the DA 40mm might be out, last time I checked it was $175 used, now it's over $300 used.

I also use the FA35 wider open than F:2.8, but not often. My "newspaper on the wall" shots with that lens at F:2 show a lot more difference compared to F:2.8 than, say, the Photozone tests. However, I agree that the widest aperture is still quite useful if not essential at night. K20d ISO 1600 FA35 at F:2 1/20 AF540FGZ flash. The bear was moving quite rapidly.
