i think the sky is the limit to be honest.
you can print as large or as small as you want with 35mm
you can take it with you wherever you want, its nostalgic, its new
the lenses are as sharp or as soft as you want. 35mm is really a great format.
and with the whole hybrid electronic thing, you can make, big-negatives and alternative process prints ...
i am sure if you asked what the limits were of MF or a fixed lens MF/TLR people would say
how you will be limited ...
just use what you have and learn what YOUR limitations are, usually it is the person who is limited, not the equipment.
