Question: Which pentax lenses have the ka mount!?
Best Answer - Chosen by Asker:

There isn't a specific series of lenses!. The KA mount was introduced in 1983!. Any Pentax lens after that date will almost certainly have the KA mount!. These lenses have 'SMC Pentax-A' engraved on the lens near the front element, and have a green 'A' engraved on the aperture ring just beyond the highest number!.Www@QuestionHome@Com
