It looks like Sony is bringing over more than just the lens.

Their HVL-F56AM and HVL-F36AM flash units look like rebranded 5600HS and
3600HS Minolta units. The only question is will the mounts be
compatible? I wonder the the A100 will be able to mount the current
Minolta units or be able to wirelessly control them, and vise versa?
