Can I adapt the pentax 28 105mm f 3 5 5 6 to sony e?
I don't have anything on this site that confirms the Pentax HD D FA 28-105mm f/3.5-5.6 ED DC WR works on Sony E. The lens page lists its only mount as Pentax K, and it's an autofocus lens, so I can't tell you how it would behave on an adapter.
What I can say is that the Lenses guide covers adapting older manual-focus lenses to mirrorless bodies. Mirrorless mounts are shallow, so those adapt easily and cheaply, but that's a different situation from carrying autofocus over. Check an adapter's listing for what it supports before you buy.
