I know, I should ask these questions before I started, anyhow......

I decided to have a play with a bellows set I bought from here on my Minolta XE-1 today for the first time and I want to make sure I am doing the right thing.

OK, I found that the 50mm lens I had would give me focal distances too close to the subject, so I used a 80-205 F3.8 Zoom. Apart from lens quality, would I have any issues using such a lens? I found for focussing, I had much better control.

Secondly, I read a lot around the traps about exposure compensations, based on the extension. If I were to stop down the lens and use the meter reading from the camera while stopped down, would this be sufficient to get a close enough reading? Or am I missing something else?
