SOURCE: trouble focusing with sigma 70-300 DL macro super lens
It will not focus on anything closer than 5 feet.
(From Sigma lens literature) Capable of macro photography, this
lens has a 1:2 maximum close-up magnification at the 300 mm focal
length. It's the ideal high performance lens for portraits, sports
photography, nature photography, and other types of photography that
frequently use the telephoto range. It also has a switch for changeover
to macro photography at focal lengths between 200mm and 300mm with a
maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing
distance is 1.5m / 59 in. at all zoom settings.
SOURCE: canon 30d with tamron af 70-300mm di macro lense showing error 99
'Error
99' indicates some problem with the AF contacts. This is a common error
in Canon lenses. It could indicate a very simple problem like dirty
contacts or a much serious one like the breakage of USM cable. Alternately, it can also be a card error or camera error.
First
remove the lens, battery and card and leave the camera like that for
about 30 min. After that, insert a fully charged battery and switch on
the camera. If the error still shows up, it is a fault with the camera
and has to be serviced.
If not, turn the camera off and insert the card. Format the card in the
camera and depress the shutter button. If it shows an error, the card is
faulty.
If not, try cleaning the lens and body contacts (the metal
contacts between the lens and body) using a pencil eraser. Be careful to
hold the body facing down so that no dust falls inside. After cleaning
both the lens and the body contacts, re-attach the lens and try
shooting.
If the error still shows up, you need to take the lens to an
authorized service center.

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.
