Hello,

A question about the 645 viewfinder.
I know that it is physically impossible but on the last few rolls I shot, I could have swore that what I saw on the viewfinder was larger than what ended up on the negative.
It seems that the borders were cropped closer than what I remembered framing.
Impossible so I must be hallucinating or be confused by the large nice viewfinder?

Cheers,

Luc

The 645's viewfinder is actually 25% smaller than the negative, and shows 92% of the field vertically and 93% horizontally. I'm not sure why you got results that suggested it would be the other way around- but you might be right, that the large viewfinder led to confusion (because it sure is nice comparted to dSLRs and even 35mm's!).

Are you looking at the film itself, or prints/scans made by the lab? The latter often crop the frame smaller than the full frame.

Thanks for the answers. I know it has to be psychological

I am looking at the negative itself that I develop myself..

Cheers,

I find the viewfinder very frustrating at times. I like to use a Hartblei 45mm T/S and after taking the shot I finds lots of vignetting on the transparency. Of course everything I saw on the screen is there in the photo but it seems I am wasting a lot of film real estate when I can't really see what I am getting.

Hopefully the 645D won't have this problem and at least we will all be able to check the post shot preview.

What F-stop do you use ?.
IMHO my shift lens (PC-Angulon from Schneider Kreuznach -not MF) have to stopped down to 11 when shifted otherwise some vignetting can be seen.
The advice stopping down is from the manual.
