Sigma Lens is locking up

I have a Sigma 17-70 and was using it with a Canon Digital Rebel XTi. I was using it to shoot and it was working fine, and all of a sudden it completely locked up. I have no idea what happened. It won't zoom completely in or out, it's stuck somewhere in the middle. The lens lock is not on.

This could be a bit of sand in the lens gears.

Is this lens compatible with a Canon Rebel XS digital camera

Sigma makes lenses with a variety of mounts to fit a variety of cameras. If the lens has a Canon mount then it will work with your XS. If has some other mount, Nikon for example, then it will not.

DS 126151 error

What kind of error? Err 99?
You mention DS 126151, that's the model number. This camera is mostly know as Canon EOS Rebel XTi? Also known as the EOS 400D or EOS Kiss Digital X.
If you are getting a Err 99 while shooting, try any other lens that will fit on your Canon. In most cases the aperture will become defect in these lenses. Not worth repairing if you ask me. One thing you could do, is shoot only at its maximum aperture. So that'll be F4.0 at 70mm and F5.6 at 300mm. That might work, but that might not be suitable in every situation.

Canon T3i Compatibility

The older Sigma lens will not work on the new EOS digital cameras...I've go two of them that will only work zoomed in at F4 and zoomed out at f5.6..... I shoot aperture priority with my Rebel XT and works out fine.... depth of field often shallow but, still nice shots.
There is a ton of info on the internet about "re-chipping" the lens....but, looks like too much to gain little.

Will Sigma 75-300 f/4-5.6 DL work on my rebel XTi

If the lens has a Nikon mount (as you imply in the post), then no, it will not fit. If it has a Canon mount, then yes, it will work fine on your Canon Rebel.

Sigma 28-300 3.5-6.3 won't focus

Did it ever work on this camera?
I have seen some Sigma lenses that are auto focus on canon film cameras but then when put on the digital they dont work right. If you have used it on this camera then make sure the lens is clean.sometimes dirt on the front wil make it try focusing on the dirt. Next try focusing in manual focus to make sure the focus is working. Then take the lens off and then put it back on and make sure it clicks into place.

Let me know if none of those things work. also make sure to try focus on something close and somthing far away.

let me know how it works,

Hey kgconstruct,
The lens description that your posting is categorized under is a 75-300 f/4-506 DL lens for Nikon AI. If this is correct then no this lens won't work on a Canon camera. I am assuming this isn't correct and the lens you have is for a Canon camera, and if this is true this lens should work on the XTI. If you’re thinking of buying this lens I would go to a local camera store that carries this Sigma lens and try it out first to make sure you like it. I hope this helps!

Go Ahead. Use Us.

Lens Compatibility

The XTi does not have a "full-frame" sensor, so vignetting should not be a problem with this lens.
