About two weeks ago, I took delivery of a Canon Elan 7 from an E-Bay seller. The seller listed it as, "Excellent condition, and excellent working condition." I tested it upon receipt, and found the AF-selection button (rear, top-right) to be non-functional, as such it is ALWAYS in AUTO-AF (all points selected). Considering the listed condition, I contacted the seller, and he immediately refunded my entire purchase price, including shipping. He also told me to keep the camera; it was not worth the trouble of re-shipping and re-listing. Very generous.
I threw the camera in a closet, intending to donate to a local HS Art department (everything else works fine). Today I got to playing with it, and discovered a combination of Custom Functions that allows me to select any INDIVIDUAL AF-point. The broken button still doesn't work, but I can use a camera where I can select any individual point. I cannot select AUTO-AF (all-points), ever. Like I said, the broken button is still broken.
My moral dilemma is, I can use this camera as it is. Should I return the refund? Had it been properly described in the listing, I would not have purchased it. I can't use AUTO-AF, but I would never do that anyway. When I thought it was ONLY useful for AUTO-AF, I sought and obtained a refund. I now have a camera I can put to its intended use, even considering the broken button. Do I give this seller his money back, or not?
