With these adapters, usually the bayonet fitting part (at the lens side) is
a separate chrome plated part attached with screws on the black tube.
I guess you can sand the black tube a bit and reattach the chrome plated
part. However, keeping it perfectly flat could be a challange?
Hmm.. now that I think about it, I have a slightly too long Lens Turbo
adapter myself which I could fix that way, maybe. Would the distance
between Lens Turbo elements and the sensor be less critical compared to the
elemens and the lens? Does anyone knows?
