lensbaby makes something exactly like an imageon, and the original imageon is made ... for 35mm ...
it is EZ to get similar effects with a regular 35mm lens and a technique to soften the image &c
forced to process 36 frames in the exact same chemistry .. ?
plenty of people who shoot 35mm roll their own and do small rolls
DBI or clip parts of the rolls and process it in a different time/temp/dilution/chemical
pretty much everything that can be done with LF can be done with 35mm.
the only real limitation is the person using the camera ...
