Roundshot 35/35 questions

[jamiehy <jamiehy@xxxxxxxxxxxxxxxx>]

I'm still thinking of getting a roundshot 35/35 and have a few questions
about them.
I know it's fixed focus- how does it do  keeping focus at 2 meters to infinity?
I know it turns at an exposure rating of 1/90 sec and the slit size changes
to accommodate different effective shutter speeds. Does the slit size
noticeably effect sharpness of the image with this camera? How wide a print
can one make before  the image starts to look fuzzy?
I'm curious to know what owners think the limitations are, and how the
different settings might change image quality. Thanks for your help- Jamie
