It varies by manufacturer and by lens, just like for Canon. But in general, quality is slightly lower, and quality control issues are slightly more common.
Yes, it's possible to use an adapter to mount a Nikon lens on a Canon body. You lose AF and automatic aperture control, but AF confirmation is retained with a chipped adapter. Note that the reverse isn't possible - you can't use a Canon lens on a Nikon body (and retain infinity focus, at any rate).

It all depends on how picky you are. Some third party lenses are very good, and a very few are excellent. But the really cheap low cost ones are a big compromise.
Generally, third party lenses have slower autofocus, and some are known for poor autofocus accuracy, which can mean fuzzy images if not adjusted. You can never be certain that Canon will not make a change in their camera bodies that will cause some or all third party lenses to stop working. This has happened twice, as I recall with Sigma, but Tamron and Tokina haven't had widespread issues.
I prefer Tokina lenses, but they have a limited selection, and slower autofocus.
Finally, there is resale value. Canon lenses tend to hold their value better, and if you find a good deal on a used one, the value might increase over time. Plan on a big hit if you have a third party lens when you go to sell it. (there are only a tiny number of exceptions with the really high quality lenses)

I have a sigma 70-200 f/2.8 v2. As a lens i love it, the AF is quick and accurate and the images are crisp.
However the biggest issue I have with sigma is that their warranty service is awful. Getting any feedback on how long a repair will take or where your lens is is like pulling teeth. In the end they did return it to me fixed, with a relatively quick turnaround - but it's very frustrating to really not know what's going on until they mail it back.
On the plus side, mine did come with a 4 yr warranty

I have a Tamron 28-75 f/2.8. If you manage to get a good copy, the lens will not disappoint!
The lens is comparable to Canon's 24-70 f/2.8L. The tammy is slightly less than half the price of the 24-70 and the image quality is on par.
Only issue with 3rd party lenses is that you lose the L quality durability of Canon's lenses and the AF/USM. The Tamron sometimes hunts a little more than I would like it to and it is a little noisy when focusing.
If you do a lot of research, you will find that both Sigma and Tamron have their share of lenses that people rave about.

Agree with the previous sentiments. Slower and usually noisier autofocus. Bigger range of quality control tolerances. That said, I own a Tamron, Tokina, and a Sigma for my Canon and I love them all.
Would I prefer to have the Canon EF-S 17-55 f/2.8 IS over my Tamron 17-50mm f/2.8 VC? Sure. But my Tamron is very sharp and focuses fast enough. Oh, and it costs about half as much as the Canon.
Sigma 30mm f/1.4? Plenty sharp, faster aperture, and better built than the comparably priced Canon 28mm f/1.8.
And my Tokina 11-16mm f/2.8? Built like a freaking tank. To get the faster aperture and to save a couple of hundred bucks, I'm glad I got it over the Canon 10-22mm.
At the end of the day, if money was no object, I'd probably only buy Canon lenses. But, money matters, and sometimes Canon doesn't make exactly what I'm looking for.

Same here. Likewise with my Tamron 28-75, over having to go with the 24-70's from Canon, or the ef-s 17-55, all of which would have cost me 2-3x as much.theqspeaks said:
That said, telephoto wise, I owned a Tamron 70-300 that was nice, but, I was never really happy with the pictures. Just picked up the 70-200 f/4 IS L instead (granted, at 2x the price), and just shooting the first weekend, I was blown away at how much better it was. I think the other manufacturers do well in the prime and wide-angle area, but, I've definitely been less impressed at their tele's.

Well, a cheaper version of the 18-135 doesn't really exist...since its cheap as it is already at $300ish. Tamron makes an 18-200 in the same price range, but, all super-zooms like that sacrifice quality for convenience.Koen_S1 said:
If you're not auto-focusing much, can I ask what you shoot the most? Cause that would give us a sense of what lenses to suggest. If you're shooting a lot of landscapes, then we'd suggest a wide lens....if you're shooting sports, it's something else.

Perhaps not relevant now: for the price the 18-135 canon is the best value and quality.
Boy o boy - if your open to using manual focus your going to get interesting advice.Koen_S1 said:

Off topic, but man, I got the same lens over the holidays, and it is AMAZING!! Blew away my previous Canon 70-300mm IS. The 70-200 f/4 IS L is the best lens I own, by far. Sharp wide open, sharp at all focal lengths, fast and quiet zoom, great build quality, excellent size, and great IS. Just a joy to use.
Haven't used a 3rd party tele, but I think I'd agree that I'd probably only go 3rd party for wide and normal focal lengths.

Sigma, a couple of real good ones offered.
Tamron,a few real nice ones available.
Tokina, 11-16 very nice.
These are the best three, third party, (affordable) ones available. The only downside to third parties is the reverse engineering. Ten years from now the AF,IS, might not work on the bodies that Canon is offering.

I’ve purchased a half dozen or so Tamron or Sigma lenses over the years. Generally I’ve gotten what I paid for, although the 3rd party manufacturers do seem to get more complaints about quality control. The only issue I’ve had is that as my image standards have increased, my satisfaction with my 3rd party lenses has deceased, but I suppose one could say that about any sub-$500 lens.
To get a comparable lens to the Canon 18-135 at a lower price, you’re probably going to have to forgo Image Stabilization, which could be a significant loss.

Like most people have said, there are some great 3d party lenses. I had an old 105mm macro Tamron. Sharp and produced great images. Keep in mind though,some features of the camera/lens interface, may not be available. Such as peripheral illumination correction and micro focus adjustment. Not a huge deal for most, but something to consider.

Currently I´m not shooting a lot, but I´m planning to buy a new camera, probably the T3i, and I´d like to shoot landscapes, a little sport (karate, but really not that often) and I´m filming a lot.preppyak said:
Basicely I´m looking for an allround lens that has enough zoom but also is good for filming.
Oh, and do you guys think that as soon as the T4i is announced the price of the T3i will drop?

Wasn't the 18-135 supposed to get the new quiet / silent drive soon? If so you may want that for video use.

yes, I thought so to, it should come with the new T4i right? But then again theres the price of such a sweet thing...
[/quote]
Î expect a substantial jump in price also
.Video shooters will be happy but regular shooters not, unless there's some other improvements. :'(
