2X convertor for Canon AE1-P

greenspun.com : LUSENET : Canon FD : One Thread

I'm pretty amateur with my camera, but I just picked up a used 2X convertor for my camera, I can mount it to the camera, but I can't mount my other lenses to it unless I take their aperature setting off of auto. Am I doing something wrong, or just need to use manual set when using the 2X.

You have an older converter that doesn't have the plunger for activating the auto exposure function. If you look at the mounting flange of your camera, you'll notice a small hole in the flange at about the 8:30 position. A small pin extends from the lens when you move the aperture ring to the AE position. That pin and the lack of the corresponding hole in the converter flange is what is causing your mounting problem. Your best bet is to get another converter. My recomendation is the Kiron 7 element 2X converter.

Hi Gary; I dont know if you got the right answer on the lenses convertor or not. 1.the Canon AE1P uses "FD" lenses so the convertor needs to be a Canon FD convertor, now you didnt say what focal lenght your lense are (50MM) or what ever. So lenses from 300MM down to about 35MM uses a canon FD type B convertor if above 300MM its a type A. Now people say you can use other covertors and you can but you get what you pay for. Along with the good you you get longer focal lenght you also get some bad, but you can live with them they are f/stop you loose about 2 and the focus may net be as sharp. Let me know if this helps.
