Model Number: KF-AAL Compatible Lens Mount: Sony (Minolta) A-mount Compatible Camera Mount: L [Bayonet] (Leica, Panasonic, Sigma) Features: Mount conversion, with aperture ring I purchased this to use Minolta lenses with an L-mount camera. Since Minolta lenses don't have an aperture ring on the lens itself, I bought this to control the aperture. I've only used it a few times for test shots indoors, so it's in good condition. This is a used item. Please understand that it has been stored at home (in a dehumidified storage box). Returns and refunds are not accepted. Feel free to ask any questions!
