Hi,
I keep hearing these 2 terms.
Could someone please give me the pros and cons, as I have a Canon EOS 500d (cropped body), and considering a upgrade.
I do street photography, portraits and events.
Thanks
Riaz
Some of this has already been said...
FF, has a bigger sensor than APS-C (like your 550D.) FF cameras generally have better performance particularly at the highest ISO's but any difference may only be visible when printing BIG, cropping a lot or pixel peeping.
With a FF camera you'll probably be using longer focal length lenses and this gives the effect of shallower DoF. This may be an advantage if you're going for shallow DoF but it's a disadvantage if you're going for deeper DoF and may push you to use smaller apertures and possibly longer shutter speed and / or higher ISO settings.
A FF camera and lens will generally be both bigger and heavier than an equivalent APS-C camera and lens set up.
Because APS-C has a smaller sensor you get the effect of having longer focal lengths. This can be an advantage when shooting some subjects, like macro or birds in flight.
APS-C may give you greater resolution.
An APS-C camera + lens will probably be smaller and lighter than an equivalent FF set up.
Because an APS-C camera has a smaller sensor you'll probably be using wider lenses and this can give the effect of deeper DoF and you may be able to shoot at faster shutter speeds and / or lower ISO's than you would with an equivalent FF camera and lens set up.
APS-C cameras are generally considered to give slightly lower image quality than FF cameras but you may have to print BIG, crop a lot of pixel peep to see any significant difference.
