Now you're getting me confused ;-)

For an adapter (without lens elements) to work, the register distance of
the body *must* be less than the register distance of the lens.

EOS register: 44mm
Pentax register: 45.46mm
Nikon register: 46.50mm

Oh God.

You're right.

And so was I when I posted:

1mm out!

and going the wrong way. Well if I couldn't mill 1 mm off the back of a
Limited, and stick a Nikon flange on, my name's not Dr Frankenstien.

Anything's doable. Send 'em along to me Herb :-)

It's that bloody Allingator!!!!!!

I'm going to spend one year collecting all the vomit my cats eject, bag
it frozen in small hessian sacks, and have it shipped over to be dropped
from a Sikorski Skycrane onto Pete Alling's head.

Lucas, I owe you an apology.

Herb, it's still doable. 1mm would have to be removed from the back of
the lens. I'll look into it properly once my grey matter has receded
several hundred degrees in temperature.

Now I'm going to lie down in a small dark room.

Good night.



Cheers,
