SIGMA 28-80mm zoom lens, 55mm filter diameter, with macro function. - Brand: SIGMA - Model: 28-80mm - Filter Diameter: 55mm - Macro Function: Yes - Lens Type: Zoom Thank you for viewing. I recently purchased this on Mercari, but it doesn't work with my camera (Canon Kiss Digital X) - it displays an err99 error - so I am putting it up for sale. (It's a shame I can't use it, as the lens itself is clean and the scenery looked good through the viewfinder.) This lens should work with Canon film cameras. For cameras from other companies (SONY, OLYMPUS, PENTAX, etc.), it may be possible to use it with an adapter. It is likely not compatible with Canon digital cameras. Please understand the above before purchasing, and note that all sales are final with no returns.
