Quantaray 70-300mm lens for Canon mount showing err-99 in Rebel XTi?

Question

I have two lenses, the kit 18-55mm and Quantaray 70-300mm macron/zoom. The Quantaray lens stopped working, it shows Err99 when mounted and the camera is switched on.

Do anyone has such experience with this lens? Also is there any lens repair shop in Chicago to repair this lens?

Answer 1

i believe error 99 is bad communication with the lens, if it's only that lens that's doing it try returning it if you can, or getting it replaced with the warranty. if it starts doing it to you're other lens too you may be experiencing the XTi blues and have to replace or repair it. but I'd try checking Canon.com for a firmware update for it...
