EF vs FF

[james_smith20]

Hello,

 

I'm still learning all of the differences of the terms. I would

like someone to please explain to me what EF means vs FF. I read a

post of someone looking to upgrade to FF in a couple of years. I

think someone responded to him about the 5D bieng FF. I am looking

to upgrade to the 5D from a 20D and I am wondering if my lenses wil

(all Canon) will work on the 5D

 

Thanks

James

LOL.

 

You're talking about two totally different things!

 

EF = electronic focus

 

FF = full frame (instead of digital 1.6x crop)

 

HTH = Hope that helps!

Maybe you mean EF-S which is a mount (derivative of the EF mount) that can only be used on EF-S cameras (300D, 350D, 20D). These cameras all have a 1.6 crop.

 

To throw another thing into the mix, 1D cameras have a 1.3 crop.

 

The 5D is a FF (full frame) which means it has no crop factor.

 

If you have the 10-22mm, 17-85mm, 60mm or 18-55mm EF-S lenses, they won't work on the 5D.

EF actually stands for 'Electro Focus'.
