I'm looking for a big lens for my k20d.I do all types of subject matter especially nature and sports and would like to have a decent "fast"lens in the $1000-$2000 price range.The feedback on the Sigma 50-500mm f/4-6.3 isn't too bad and it's only around $1000.It's a heavy lens but a lot of people like it.The lenses that i have for my k20 are 18-55 Pentax - 18-250 Pentax- 70-300 quantaray which isn't too bad for the money--$149. The moon shot was taken with the quantaray-hand held at 1/750 f9.5 ISO800.Pentaxians are knowledgeable people and i will be looking forward to your suggestions. charliezap

Many people have that Bigma, but it is big, and not especially "fast".

The current Pentax 300/4 is about $1200 last time I looked, so getting something faster/longer in your price range is probably a remote chance, even on the used market.

I'm supposing you want a large range zoom rather than just long telephoto. The Bigma comes to mind, as above, although there are other lenses that are a little 'faster' but don't have the same zoom range.

Sigma's 100-300, 120-400 and 150-500 come to mind - check the third party lens database for more info...
