Nikon AF Nikkor 50mm f/1.8D

Yes, there are articles and reviews up the wazoo on this, but what are your experiences?
I am considering the Sigma 10-20 and Canon's 10-22.
Which is better? Sigma is cheaper, but if IQ is at least similar to Canon, then...
I really cannot justify the 10-22 expense, so I am hoiping the Sig is almost as good. I have a line on a used one...but want some feedback before buying. I am also waiting on images from that used lens - at 100%.

I own the nikon version of the Sigma 10-20 and I really like it. Its sharper than I expected and I'm doing some unconventionl things with it, like portraits!

My 6th and 7th highest scores here are with the Sigma 10-20, and I have a 6.2 with it at the moment in free study.

I'd say the image quality is very good. :)

I have the Sigma 10-20 as well. I chose the sigma because it's not the EF-S format lens and will work on Canon's non-EF-S lens cameras. This lens is NOT for full frame sensors though.

Doesn't that make it ef-s?

Not to put a damper on things but you have to be careful with used third party lenses.

The 40D being a fairly new camera, a used sigma lens may have to be rechipped to work.

No. That just makes it designed for cameras with APS-C sized sensors.

Ahh, so it's an ef-s lens your're saying.

It's NOT an ef-s lens. The EF-S lenses are structurally different and won't fit on non EF-S ready cameras.

Heheheh.

Let me see if I follow:

1 - It's not ef-s
2 - It won't work on full frame
3 - It only works on aps-c cameras
4 - like an ef-s lens
5 - reason to buy is you aren't tied to ef-s cameras

Heheheh

Correct. If you own a Canon 10D and 20D, you can use the Sigma on either camera. You can't use the Canon 10-22 on the 10D, but you can on the 20D.

Just messing around. Thought the part about not being tied to ef-s was funny since practically speaking you are unless you are shopping for 3rd/4th generation old cams.

I'm not sure, but I don't think the Canon 1D series is EF-S compatible either...

Well that is a major damper! LOL

If you guys could choose between the two - which one, if price were not an option?

The issue where sigma lenses needed "rechipping" was several years ago on an older generation of sigma lenses. Maybe 2 or 3 generations ago.

Unless the Sigma lens being considered is 6 or so years old or older, I wouldn't worry.

They still have to re-engineer the lens to communicate with the camera. If the lens came out before the 40D would it still work? Would you take the chance?

Good news. I posted a quick question on the compatibility issue at the Canon forum, and it's a go! I guess I am about to be the proud owner of a Sig 10-20!

It's not as much an issue of shopping for cameras as for lenses. I compared the Canon and Sigma lenses when I bought mine because I have one non-EFS camera and two that will support EFS.

It's a lens that I don't use that much so I opted for the Sigma. The results from that lens, IMO, have been impressive though. It's the only Sigma lens I own, and also the only lens I own that is designed for the smaller sensor. If I ever upgrade to a full frame sensor camera, this lens will become useless except for on my older cameras.

If it's anything like its canon sibling then I'm sure it's a killer piece of glass.

It's not the best piece of glass I have, but it's definitely beyond adequate for its intended purpose :)

No they don't.

Not until Canon re-engineers the communications protocols between lens and camera and makes the cameras non-backwards compatible. If they do that, ALL EF and EF-S lenses would need re-chipping.
