Recently the AF sensor of my Canon 10d has stopped working. Fix could be easy like a bad connector or a expensive ($350) replacement of a module by Canon. Still the camera takes great images but you have to fucus manually...
Great bargain for those with the tools and skills to fix or the one who would like something to experiment with like IR photography.
The Sigma lens is in a good shape. Selling it because I only using "L" lenses now.
