I've never noticed any problems with it. I've always used fast film and 
have made good 24 inch long prints from this.

I can only think you are holding something in the way - no 
discernible vignetting or softness at all. I do sometimes manage to get a 
finger in the picture!

You could fill a billboard.  Or you could be like some photographers I 
know and insist that contact printing is the only way to avoid loss of 
image quality. I think the negs will stand a similar degree of enlargement 
to those from a Leica etc. So if you are happy with these at x10, you will 
find you can make prints about 580x240mm from the 202. Depends how good 
your glasses are!
