Hi Everyone,

First of all: I did a search on this but with such generic keywords the results were quite comprehensive and irrelevant to my question. It's probably been answered 100 times on here, but it's not easy to find.

I also did a Google and found a very useful Wiki article:

http://en.wikipedia.org/wiki/Canon_EF_lens_mount

But I was hoping to get some absolute clarity before I make my most expensive lens purchase yet.

So, what I gather from that article is that EF lens will fit anything whilst EF-S lenses will only fit cameras with crop sensors.

Is that true?

I currently have a 600D but plan on moving up to a FF 5/7D in the next 12 months. I want to start purchasing glass with the next camera purchase in mind.

Thank you!

Tom.
 
You've got it spot on. So yeah, would make sense to just buy EF lenses as you're looking to upgrade to FF soon.
 
You are correct that the EF lenses will work on any EOS body but that they EF-s lenses will only work on crop bodies (exclusing the really early bodies). However it might be worth noting that the 7D is also a crop camera like your 600D so if that is the upgrade route you decide on EF-s lenses would work fine on this body.
