- The lens features dust and moisture sealings and comes with detachable tripod collar TS-31.
- Sigma's OS seems to face similar incompatibility problems with old analog bodies like Canon's own IS lenses. I.e. Sigmaphoto.com puts a note to many fullframe OS lenses either reading "This lens cannot be used with film SLR cameras with the exception of the Nikon F6 and Canon EOS-1v." or (seemingly making the issue more clear) "For Nikon and Canon mounts, Optical Stabilizer (OS) function will not work with film SLR cameras except Nikon F6 and Canon EOS-1V."
- Sigma reported Live View issues with the EOS 750D and 760D for lenses with SN #12676440 or later: When the Live View Mode button on the camera body is pressed, operation stops. A service update was/is available [source].
