Klipsen: If a pretty unknown company, and not necessarily primarily an optical company, can develop and manufacture an adapter that good, imagine what Canon, Nikon, Sony etc. could do!
So: Why don't they?!
They can. Nikon actually did with its earliest DSLRs (D1, E2, E2N, E3). They choose not to. They'll make more $$ selling new lenses for the mirrorless bodies, the new system lenses will be smaller and the AF system better matched, and none have any interest in supporting lenses made for other makers' cameras.
Abeautifulmind: Flash.Canon has made the compact camera I was waiting for.I use Nikon SLR's since more than 30 years but they haven't convinced me with their Nikon 1 's.
Could anyone tell me if I could use a Nikon SB-600 speed light on the Canon G1 X ?
