I've read that should you wish to ever upgrade to the full frame cameras such as the 5d for example then you should consider EF lenses and not the EF-S series.

If this is correct then I would need to buy the Canon 100mm Macro as opposed to the 60mm one as the 60mm is EF-S only.

This seems a bit odd especially as I think the 60mm Macro is the better lens to go for distance wise for macro and portrait work given the 1.6x of the
350d.

Currently have an EF 70-300 and the kit lens 18-55 which is EF-S. Looking to get a macro lens though and prob replace the kit lens with a 28-105 EF albeit losing a bit at the bottom end.

Comments welcomed.

Personally, unless you were planning to upgrade in the very near future I'd buy the best lens for you EF-S or EF. Lenses do not tend depreciate as much as the camera kit (body etc) itself so get the best for you. If you go to an EOS 5D or better at a later stage then sell the lens and replace it. Problem is that a 100mm macro on a 1.6x crop will effectively be a 160mm, where as a 60mm will be an 96mm!!

i think your missing the fact that an EF-S lens will destroy your mirror if you had a 5d.... . They only fit 300d, 350d, 10d,20d and 30d and possibly the older d30

From what I've read the 5D for example needs quality glass so you'd be looking at L lenses, which are only available in the EF mount (or possibly Sigma EX), which would be more of a consideration. I've just sold my Sigma DC 18-50 without too much difficulty and got what I think is a fair price for a used lens so I'd agree with sjameson about getting what's right for you at the moment.

If you went the 5D route, you would need some excellent L glass that is good on the edges aswell as center frame.

We are quite lucky with the crop cameras you don't see the full ugly head of
edge quality. And that's with some of the best glass.

Just a minor correction. The 10D and D30 do NOT support EF-S lenses. If you try to fit an EF-S lens onto these cameras you'll have a costly repair on your hands just like the 5D.

Personally I'd say buy the best lens for the camera you have now. As has been mentioned lenses depriciate a lot slower than cameras so you should be able to get most of your money back when it comes time to sell it. Besides, by the time you actually come to buy a full frame camera there could well be a better lens out there that you'll want to buy instead.

Glass is more of an investment than a camera, most lens's will not change their spec during their life, if you look after them they will outlast numerous cameras. My belief is buy the best lens you can aford for the job you want it to do. Try and use / borrow / hire them first to see if it is really what you want.

As for EF-S lens's cannot comment I have never had a camera that will take them.
