Some ebay sellers (of
Pentax SMC F 1.7X AF Adapter) declare that:
When mounted between an autofocus body and either a Pentax A type or M type lens, the adapter converts the lens into an autofocus lens.
The focusing mechanism is fast and snappy. no problem with Pentax SMC A 50mm f1.7 lens & Pentax SMC A 28mm f2.8 lens,
Is it possible? Anybody test it?
