I upgraded from an original Canon Digital Rebel to an EOS Rebel T2i. My Canon EF 35-105mm worked on the old body, but on the T2i the camera shuts down after a few seconds when this lens is attached. Power cycling the camera does not fix it — I have to remove the lens and battery before the camera works again. My other older EF lenses, a Canon EF 50mm f/1.8 II and EF 75-300mm f/4-5.6 III, work normally on the T2i. Is the EF 35-105mm incompatible with the T2i, or is this more likely a lens problem?

Yes it's compatible, being an EF lens. But as jrista states is a very old lens. It may have malfunctioned, or more likely need it electrical contacts cleaning. The little gold bits at the back that allow the lens to talk to the camera get dirty over time and no longer conduct a good electrical signal.
Soft pencil erasers are recommended for light cleaning, failing that any alcohol based cleaning fluid suitable for electronics should do the trick.
Or use this as an excuse to get a new lens :)

Generated from our catalog & community — verify before relying on it.
Yes — a Canon EF 35-105mm should be compatible with an EOS Rebel T2i, because the T2i uses Canon EF/EF-S mount and EF lenses are supported.
If this one lens causes the camera to shut down while your other EF lenses work, the more likely issue is the lens itself rather than compatibility. Community answers suggest the lens is quite old, so dirty electrical contacts or a fault in the lens electronics/AF mechanism are the most likely causes.
Try cleaning the lens contacts carefully (the gold contacts on the rear of the lens) with a proper electronics-safe method. If the problem continues, the lens may have an internal fault and may need service or replacement.
One other note: even if it works, an older EF 35-105mm may not take full advantage of the T2i’s higher-resolution sensor compared with newer lenses, but that would affect image quality, not basic compatibility.
