Hi all,

I'm interested to use my Rokkor lens on a modern CANON EOS DSRL (with
APS-C sensor).

I know that the distance between the sensor and the focal plane is
43.5mm on Minolta MC mount and is 44m on CANON EOS mount. This
difference between
two register is only 0,5mm.

So I'm not interested about the possibility to make a ring (or adapter)
to connect my Minolta Lens on EOS boby but (I know that is not
possible...) , but I'm interested about the possibility to dismount the
EOS flange (and if it is necessary also the electrical connector) on
the EOS body and to sobstitute it with the Minolta's flange in order to
connect correctly the lens. Then, of course, will be necessary to
adjust the distance from the Minolta ring to sensor plane in order to
achieve the rigth infinity focus.

The only suspect that I have ... is about the risk that the botton of
Minolta Lens (and in particular...the aperture pin) could touch the
mirror ... or interface with mirror box !
But I also think that the solution could be to remove the elettrical
connector on EOS Body too ...!

This solution is reversable because it is verry easy to return to the
original EOS mount.

What do you think ?

Thanksv for advice,
Mauro

Why would you *want* to do that?  The old Rokkor isn't that startling a
performer for you to go to that trouble, surely?

Buy a Canon 50mm F/1.8 for a hundred or so dollars, fits, focuses,
autoexposes, and is just as sharp as your Rokkor - and you don't have to
perform major surgery on your camera.

I agree with Colin.  I've had a Rokkor lens on my old Minolta and it
performed good, nothing that would knock your socks off.  You are way
better off to go for the Canon Lenses.  Why put a great camera through
that?
