I'm currently using a K10D with a variety of lenses and am a frequent airshow photographer but have found the AF to be a bit slow at times. I'm thinking of purchasing the K20D and also a 300mm DA* lens, has anyone else got any of these and what is the AF speed like?

Hi Rob,

Whilst I have no (personal) experience with the DA 300/4 lens, I do know from some "other forums" that the lens is a stellar performer with both the K10D and K20D. My advice, as a retailer,
would be to:

A) try the lens with your K10D (and a K20D if possible)at a local shop
to see how it/they perform (for you)

or

B) if you are going to purchase, go for the lens first (to get the reach) and see if
you need the K20D for any extra's because, god knows, you will want them

Also, if the DA 300/4 is anything like my DA 50-135. the AF (w/ my K200D) is amazing
compared to my IST*Ds

Hope this helps somewhat.

Cheers,

Jack
