For me, an Error 99 usually means a problem communicating with the lens. The four most likely causes:
1. dirty lens/camera contacts or lens not completely locked into place. 2. non-Canon lens that's not 100% compatible (Sigma, Tokina, Vivitar, Phoenix, Quantaray) 3. battery grip not fastened ticghtly enough or an original, unmodified 20D grip. 4. a problem with the AF motor or helical assembly in a canon lens causing a bind at some point in the focus range.
