In modern cameras with focal-plane shutters is there a custom as to which direction they move – whether horizontally and vertically – and on which side they start?
To the extent there is consistency in this feature on the market, what is the reason?
Citing a source from 2000, Wikipedia says:
Most modern 35 mm and digital SLR cameras now use vertical travel metal blade shutters. These work in precisely the same way as the horizontal shutters, but because of the shorter distance the shutter blades must travel (24 mm as opposed to 36 mm), the shutter blades can travel across the film plane in less time. This can result in faster flash synchronization speeds than are possible with the horizontal-curtain focal-plane shutter, and the shutter can reliably provide higher speeds....
Makes sense, but wondering if this is still the case.
