Q: 1. What would I need to mount Pentax K lenses to the Sony A6300 ?

A: As the Sony Alpha a6300 Mirrorless Digital Camera uses the smaller Sony E-mount lens mount, it is not compatible for use with the FotodioX Pro Lens Mount Adapter for Pentax K Lens to Sony A Mount Camera listed above. The options we carry that would allow you to connect a Pentax K-mount lens onto the Sony E-mount lens mount would be either the Novoflex Adapter for Pentax K Lens to Sony NEX Camera, B&H # NOAPKSNEX, the Voigtlander Adapter for Pentax K Lens to Sony E Mount Camera, B&H # VOEAK, or the Dot Line NEX Adapter for Pentax K Lenses, B&H # DODL0809.

Q: 6. so,,want to have an adapter for my sony a 57 lens to fit pentax kaf2...body???

A: I have Nikon manual focus and zeiss manual focus lenses adapted to my Pentax K3, KS2, and K01. You will likely lose autofocus capability. My cameras automatically go to AV exposure mode. The camera exposes properly for the f stop I set the lens to. The adapters I have add a glass element and I find stopping the lens down two or three stops from wide open helps image quality. Sharpness is fine, but I notice a drop in contrast. But I can control that in post processing. For me it was a reasonable investment to add several lenses to my arsenal.
