Question about Quantaray AF 70-300mm f/4.0-5.6 High Speed Auto Focus Zoom for Minolta
Quantaray makes their lenses with a variety of mounts. A lens with a Minolta mount will not fit onto a Canon camera. A lens with a Canon mount will work just fine on a Canon camera.

Your problem is a simple one: technology doesn't stand still.
Your lens was designed to work with Canon technical protocols which existed seven years ago and things have advanced somewhat since then.
With some third party lenses it's possible to send the lens to the manufacturer's service agent and pay to have it serviced and updated, but this cannot be done with your lens.
You'll have to buy a more recent lens model if you want to use it on your Rebel T1i. Older Canon lenses should mostly still work (unless Canon clearly state otherwise) as Canon will have taken their design into account on later bodies, but Canon have no interest nor any reason to make their later bodies able to use older non-Canon products.
Sorry that this is not the answer you hoped for, but I hope that you have still found it to be of some use and that you take a moment to rate my reply.

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 Though it might work perfectly with your older camera, its technology is outdated as it relates to digital cameras and can't mesh with the latest and greatest.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)

Check with your local Ritz Camera store, or find Ritz online. In the past they've been updating the chip in the lens to work with digital cameras at no, or small charge ( Quantaray is a Ritz house brand ).
