I don't have a E-1 I have the one that pre-dates that the E20, which if I am correct is virtually the same as the E1 but you can't change the lenses on it.

Interesting about the print size where you were happy with the quality of A3 prints.

I have just finished a college course and I made 3, A2 prints off my E20 and they were great, so I think the E1 should go higher without any problems.

Now I have an E3, and still use the E20
