GW...let me know your thoughts on the lack of internal focusing on this lens. How's the noise as well...compared to a regular Pentax Internal Focusing lens and also the HSM.

jelpee,
It does have internal focusing and noise is less than my 55-300mm and much quicker.

No, you're correct, but, they should be coming out with the Pentax and Sony mounts very soon from what I read.

Hi Herc and GW,

Unfortunately, Tokina doesn't make any of the lenses that have shared optical designs in Pentax mount. I've heard that there is a non-compete clause in their arrangement. In fact, I've heard that Tokina has decided not to produce any new lenses in K-mount because Pentax doesn't meet their relatively new market share requirements in DSLR sales (@ 10%), so it's questionable that they are going to make K-mount lenses -- at least in the near future.

I believe that this info came second hand from a Tokina rep, so take it for what it's worth. . .

Just as Snostorm has indicated Tokina does not produce any lenses in the K mount. Years ago they did, but not any longer. However, there are a number of lenses that Pentax and Tokina seem to share. the 10-17, 12-24, 16-50, 50-135. The optical train are reported to be the same, however the external barrell design and the autofocus clutch are different, along with the coatings used.

Its been reported by some that Pentax does the optical design on some and then each company does their own externals, etc.

nice lens, great shots. I have the DA 14mm f2.8 and the DA 10-17mm fisheye. I passed on the 12-24mm because at the time I could only afford the 14. (I purchased them a year apart, all my budget will allow)

Thanks Ira,
I had a chance to try out the 10-17 last year and was very impressed with it.
