You'd get the full FOV of the lens
what do you mean by this?
a 50mm on an MF camera has a wider FOV
It may well be the full FOV for that particular crop sensor, but it isn't the full FOV for which the lens was designed. 50mm lenses are considered the 'standard' lens on 35mm cameras for which they were designed - long before digital cameras and crop sensors. A 50mm lens on a crop sensor digital camera is now effectively around 80mm, which introduces big drawbacks when used in confined spaces where the FOV is drastically reduced in comparison to a 35mm camera or a full frame digital one.on a APS-C you get a smaller FOV all of which are the FULL FOV for that type of camera.

Of course it does -a 50mm lens on a MF camera is a wide angle lens, and it's a totally different lens designed for a different format!

All fairly obvious stuff which I find it difficult to believe you don't appreciate anyway.![]()
well, at least in fashion and portrait photography loads of super pro togs use only primes and 50mm is the most common.
I would never shoot wedding with primes, that's pretty much suicide I think but well - I think I'll never shoot weddings anyway![]()
