Chris asks…How do I know what cameras this lens fits?The lens is the SIGMA 70-300mm f/4-5.6 DG Macro Lens for SIGMA SA-7N.
anybody know and will it fit a Canon Rebel XT?mr.eos answers:The SA-7N is a good film camera but it's a proprietary lense mount. The lens will only work on the Sigma SA-7 or SA-9 camera. See the thread here:
