I'd like to add to the above that monorails really come into their own with very wide angle lenses. There's no baseboard to be dropped down, and the front and rear standards can be almost touching and still allow almost the full range of movements, especially when fitted with a "bag" bellows. That's another thing, the modular design allows bellows, backs, rails and standards to be changed and extended. Also, the larger lens board allows a wider range of lenses and shutters to be used.(posted 8970 days ago)You would need to be really strong, really deperate, really mad, or possibly all three, to use one hand-held though. }:^)
