Will a quantaray 28-105 1:3.8-5.4 Zoom lens Autofocus from a 35mm rebel ti fit on Canon EOS Digital Rebel 6.3 MP 300D?

You did not mention which lens. Some Canon digital cameras will only take EFS lens, others take both EF and EFS. Also there are other types of lens mounts made by Canon.

Cordially,

If your lens is a EF mount and your digital can take EF lens the answer is yes.

Cordially,

Yes.

Quantaray makes lenses with a variety of mounts. A lens with a Nikon mount, for example, will not fit onto a Canon camera. Assuming you have a lens with a Canon mount then yes, you can use it on your Rebel.

DS6041 is the model number for Canon EOS Digital Rebel or 300D. It is a 6.3 megapixels DSLR camera from Canon.

You need to by one with a Canon EF fitting.

Quantaray is a private label lens made for Ritz Camera. They make this lens to fit several different camera brands including Nikon and Canon. The only ones that will fit a Canon camera body are the ones with the Canon EOS mount. If your Quantaray lens doesn't have an EOS mount, then it won't work on your Canon camera. You can take the lens to any Ritz Camera location and they can help determine which mount it has, and which cameras it will fit.

I have been researching this problem and found there's nothing you can do. Appararently, the quantaray, being an older lens, wasn't made to work with this latest era of cameras. Though it might work perfectly with your older camera, its technology is outdated as it relates to digital cameras and can't mesh with the latest and greatest. By the way, most of my questions were answered on the Digital Camera Resource page (www.dcresource.com)

how cold - it may be a chip problem on the 70-300 whats the lense make/model that works and lens make/model that only works when warm
