Hi,

I am abit confuse of which lense to buy for my canon 350D.

there AF and EF, will both fit ?

what types of lense that cannot fit when people are selling ?

thanks

i have ef i think , you'll also get US(ultrasonic) and LS i think the pro versions.
in fact my new big beast is apo dg.

confused - i am.

Go for EF lenses, I have an Canon 10-22 EF and canon 24-105L, The L is much better built and probably wasted on me but it is smooth fast and sharp but also bloody expensive. I had a Canon 28-135 EF lens which is great value if you want something not too expensive but with a bit or range. Some of the Canon fit Sigma lenses are really good value as well.

i have to admit that all mine are sigma made.

Your camera can use either EF or EF-S mount lenses.

EF lenses are designed for both full frame and APS format cameras, EF-S lenses are just for APS format (which includes the 350D).

The other letters you'll find used are 'L' which is Canon's professional quality stuff and 'IS' which means 'image stabilisation' - if you shake, the lens shakes the image to compensate!

Both EF & EF-S lenses will work with your 350D. EF-S lenses are not designed to be used with full frame bodys.

An L lens is just the top of the range Canon lens, you can tell an L lens by the red band on it & the L telephoto lenses are a white colour.

IS is short for image stabilizer & USM stands for Ultrasonic Motor.

If your buying a new lens as long as its EF or EF-S it will fit your 350D or if your looking at getting a non Canon lens like a Sigma ( people tell me the Sigma 17-70 is a quality lens for the money ) just get the one that is a Canon fit.

Just to add to what others have said, AF is Nikon's acronym for Automatic Focus (or something like that). Canon call theirs EF for Electronic Focus or EF-S for Electronic Focus - Short.

Lenses made by Nikon (Nikkor), or any other major camera maker such as Olympus, Sony or Minolta will not fit a Canon - they all want you to buy proprietary lenses.

So-called "third party" lens makers generally make lenses for other manufacturers' cameras (although Sigma also make cameras), so you can buy lenses made by Sigma, Tamron, Tokina etc, as long as you buy the "Canon fit".
