Ken, Canon's lens brochure says the EF25 can NOT be used with the following; any lens below 20mm focal length (ie 14mm, 15mm fisheye, 20mm), the 24/1.4, 50/1.0, 45/2.8 TS-E, and the 17-35mm and 20-35/3.5-4.5 at the shorter focal lengths. Your lenses should be OK with it, so either it needs a clean or yes, you have a lemon. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
