Lens question

I have a question about lenses, Canon in particular. I have a Digital
Rebel 300D and am looking to purchase a 50D in the next year. I'm
looking at a EF 28-135mm IS USM lense. Will this work with both
cameras? What's the rule of thumb for Canon lenses and their
'compatibility' with older and new cameras?

Thanks,
Chris

The EF 28-135mm IS USM lens will work on both the 300D and the 50D. I
bought that lens when I bought my 10D and really like it.

EF lens will work on all Canon DSLR cameras as well as Canon SLR cameras
made for autofocus lens. The EF-S lens will only work on the so called 1.6
crop sensor Canon cameras made after the EF-S lens were introduced. For
instance, an EF-S lens won't work on my Canon 10D, a 1.6 crop sensor,
because it predates the introduction of the EF-S lens. The EF-S lens are
made especially for the 1.6 crop sensors and the mount won't allow them to
be affixed to a full frame sensor or film camera.

In general: a DX lens mounted on a FF camera will typically result in
vignetting under at least some condition (apperture/focal lenght
combination). The other way round, i.e. mounting a FF lens on a DX
camera is no problem.

Canon specific: Any EOS-lens can be mounted on any EOS-camera. However
the EOS system (using the EF mount) is completely incompatible to the
earlier FD mount system.

keep in mind that any ef-s lens is incompatible with an ef mount, while
any ef lens will work on any eos camera, crop sensor or not. nobody
cares about fd lenses anymore, they've been paperweights for a couple
of decades.

More's the pity, because Canon FD lenses still are some of the finest
lenses ever made. That Canon orphaned them without even a single
digital body was a big betrayal of customers and a good reason to avoid
Canon products. If and when I buy a dSLR it will probably be a Nikon,
in part because Nikon has respected its promises and its customers.

were, not still are. modern lenses generally are much better than ones
designed 20-30 years ago and lens coatings have also improved. also,
nothing stops canon from keeping the same optical formula in a newer fd
lens, if it's actually as good as you seem to think.

fd lenses work on 4/3rds bodies, using an adapter you claim to have
used despite it not having shipped at the time you made the claim.

Fair enough, should have pointed that out explicitely.

there are no problems using any nikon af lens on any nikon body either.
the only issue is that entry level cameras won't autofocus old lenses,
but people who buy those entry level bodies aren't likely to have old
lenses so it's a non issue.

nikon saw that most people buy 1-2 lenses with the camera and that's
it, so they made a smaller and lighter camera and sales skyrocketed.
the d40 was one of the best selling dslrs, so obviously, nikon's
marketing nailed that one right.

meanwhile, canon users can't *ever* use old manual focus lenses (and
the adapters don't work well, if at all).

depends on the body. low end cameras, no, mid and high end cameras yes.

that's true, however, nikon's mount wasn't as limited so they were able
to maintain compatibility with old lenses, as did pentax. minolta, on
the other hand, changed the mount for no reason and came up with a
weird hotshoe.

people who buy entry level cameras don't usually buy a lot of old
lenses and people who have a lot of lenses don't usually buy entry
level cameras, so it isn't actually much of a problem.
