Originally posted by LeDave Just because Tokina has it doesn't mean Pentax will have it. Tokina does not only buy Pentax designs and optics, but they also have their own designs they engineered from the ground up. I'm guessing that if it hasn't been released already, it's purely a Tokina design and Pentax did not have any part to do with it. Your best luck would be a DA* 12-24 or a Sigma 10-20.
The Pentax 12-24 in Canada costs around $ 1299 Canadian dollars(I know...unbelievable)...great lens...but that price !!
I tried the Sigma 10-20 on my K10D...not a bad lens...at least the copy I tried, but I've heard / read on some threads, that some try a number or examples before they get a good one.
But I'm still thinking of a Sigma 10-20 mm F 4 version.
