Tokina sd 70-210mm k mount

Does this Tokina function the same as Pentax-a series lenses, when set to A on the aperture ring, on my k30?
That is, will I get a view of the f-stop and shutter speed, along with EV bar, in my viewfinder.

It should; however, you might want to check for the Ricoh pin on the mount before using it on your K-30. According to the lens database entry for the lens , it seems that some copies may have the pin.

The two Tokina KA lenses that I have (28/2.8 EL and 400/5.6 SD) have Ricoh pins that never interfere with anything. I just left them there.

I have the "Tokina SD 70-210mm 1:4-5.6", which I bought new in 1985. It has a KA mount with aperture ring A setting.

I think it was not advertized to be Ricoh kompatible, but it has a Ricoh "ball", not a "pin". I never had a problem with Pentax AF bodies, neither film nor digital (K200D).
