Tokina 16-50 and 50-135

Just yesterday I was going through some magazines in store and noticed that Tokina has announced 16-50 f2.8 and 50-135 f2.8. Well is this coincidence that Pentax has just released the same lenses? Or did they sell out to Tokina? Anybody knows???

Tokina co-developed the lenses with Pentax. I'm not sure exactly how much co-operation there has been done and what, but as I understand it Pentax did the optical design.

Well it's certainly not coincidence. Pentax and Tokina have an arrangement or agreement, in which we will see very very similar lenses being released by Pentax and Tokina. The Tokina versions will not be available to us Pentax users (only to Canon and Nikon). The f/2.8 zooms are one (but not the only) example of this arrangement... and in this case the Pentax version has the added advantage of SDM and sealing.

Beyond that I can't really say. At first there was talk of Pentax and Tokina working together on the designs. Some of us wondered if Tokina was perhaps doing most of the designing, as it wouldn't be the first or last time that Pentax basically re-badged a third-party lens design (as have Nikon, Sony etc). But others will swear blind that they're 100% Pentax products. So far I think we still haven't seen anything conclusive one way or the other.

It means that C&N fans will not only have their good glass (and sorry for saying, I think there is some) but they will be able to ejoy even re-labeled Pentax good glass. What a shame. Instead bringing more people to Pentax they let other brands owners have them too...

BUT the Tokina versions are NOT stabilized on Canikon bodies. SR is a lifesaver on the 50-135mm, especially indoors.
