Q
Is this suitable with olympus epl-9 using my pentax bayonet lenses? some lenses have aperture rings.
Answer Question
A
The benefit of this adapter is that it’s suitable for Pentax DA lenses that don’t have an aperture ring. The silver ring on the adapter controls the aperture linkage on the back of the lens. Although a lens might typically have a aperture range of f2.8 to f22, the adapter only has 5 stops, and the real value of the aperture is guesswork, however a mft camera will have no trouble gaining the correct exposure. Lenses with their own aperture ring can still be used on this adapter, you just need to see the adapter to ‘open’.
