Thanks everyone.
I think I will get the 50 and 200 and the tube accessories, i can probably negotiate around £40-50 for those so probably worth it? The only odd thing about the 200 is that the focus ring seems a little stiff... not sticky, its probably meant to be like that? but it does more than a full turn for focusing and with the friction its not really suitable for fast manual use but i do like the 50 and its probably worth keeping them both for something to play with

I'll probably give the rest back, i'd rather not get a bunch of stuff i'll probably never use - I'll wait and get something fancy when I go on hols to NY in September!

Cheers.

Thanks for the tips so far...
The only thing i would say for the 70-200 is that it seems to fix its AF faster than my new DA 50-200... but if the quality isn't much better then i'll probably let it go.

I wonder if the 29-80 is better than the 18-55 kit lens that came with the K10D?

I don't see myself using film really - and like you say i think the two lenses i mentioned above came with the Z-20 body as i think he'd like to sell those as a set.

I'll probably grab the converter and tubes for next to nothing. I will keep the 50... having played with them all, knowing nothing about their worth or quality, i did pick out the 50 as my favourate of the bunch.

I'm not sure if i'll use the 200 as i have the 50-200 DA unless someone advises strongly otherwise??

Hi peeps,

I have the oportunity to get the bits and bobs listed below but havent got a clue how good/valuable they are... would someone in the know please give me an idea of how much each item might be worth 2nd hand, and whether they are any good? I will use them with a K10D and am not detered by using manual mode

Also, could someone give me a nudge in the right direction regarding the extension tubes? i've never used these before so dont know why i would use one size over another or if theres common practice for particular focal lengths?

SMC PENTAX-FA 1:4-5.6 70-200mm
