Had a chat with another canon user a few days back and he mentioned that he managed to get a nikon DK-17M eyepiece magnifer to fit onto the viewfinder of 350D at TCW with the help of a salesman in the shop. But when i check at the shop the person I talked to mentioned that this is not possible as the adapter and the eyepiece dun match (different size but you need to file at the sides of the screwthread of the eyepiece). Anyone had any experience attaching the nikon eyepiece to their 350D or 20D viewfinder?:sweat:
