I have that same adapter. It works well, but the process of setting it to the 
characteristics of a lens is tedious and 
eats up shutter cycles. I used my old 300D for that. I can't imagine using one 
regularly on several lenses. At that 
price, I'd just buy one for each lens and set each up only once. That should 
work very well.

It's proven useful to me on my Tokina 600/8, not so much for focus, although 
that works pretty well. The big advantage 
is the info it gives the camera body so it gets exposure right. Having useful 
EXIF is nice, too.

Before, I had to go to manual, set at least -2 exposure and chimp to get long 
distance landscapes right. Tedious. With 
the EMF adapter, the exposure is generally right first time. I do have to lie 
to the camera and say the lens is f5.6, as 
Canon bodies won't deign to try focus confirmation with lenses slower than 
that. I've never tried it in the dark, but 
the focus confirmation has worked for me.

Exposure works well, too, as the camera can't tell that the lens is slower, 
rather than the scene being less bright. It 
seems that all the camera needs is a lens that reports back to it, to get 
exposure right, not necessarily that it 
reports the truth.

As to fit, this adapter fits most lenses I tried it on rather nicely, mostly 
Zuikos, but was loose on the 600/8. Once I 
knew I was unlikely to use it on anything other than the 600/8, I put some tape 
on the mount face, which was just right.

You can see the problem the makers have. The same adapter is a good fit for 
Zuikos, too tight on a Vivitar and too loose 
on a Tokina.

Adaptable Moose

What if the Hokey Pokey *IS* what it's all about?
