Is it the bower adapter? If I am correct, you can not adapt FD to EF mount because of the flange focal distance of FD Glass, they will physically adapt, but you will not be able to acquire proper focus. I have the bower adapter and this is the problem with all my FD glass.

nope it's the Zykkor adapter...same as this one:

i'm going to go to Samy's on saturday and see if it fits some FD glass and just see how it looks before i buy anything.
i did get it to go on my camera..just not sure about the screw..do i unscrew it.. put lens in, then screw it back in?
i'm sure someone at Samy's will know....

this is indeed very much looking like the Bower adapter which is almost a generic item being mass produced, sold and rebranded almost everywhere over the evil bay...
it really is pretty straightforward :
just turn the adapter ring into the open position and remove both caps.
mount the adapter on the camera and turn it until it locks into place.
mount the lens and twist it in the same direction until it clicks.
then turn the adapter's ring into closed position to arm the aperture lever.
works a treat...
better at small apertures for decent sharpness because the inner optical element is quite cheap...

FD lenses cannot be adapted for Canon's EF mount without losing infinity focus, unless a glass element is used to correct that. Infinity focus is not the only issue; at shorter focal lengths, the lens can only be used for macro work. I had a Canon 35mm f/2.0, and when I tried to use it with an adapter without the glass element, I was only able to focus a few inches in front of the lens. Eventually, I found it too limiting, so I got rid of it, which is a shame, because it was a great lens.
The glass in the adapter will significantly degrade the image. It looks OK at around f/4.0 or f/5.6, depending on the quality of the adapter, but when it's open more, the image is very soft with plenty of chromatic aberration. In my opinion, using FD lenses with an EOS camera is just not worthwhile. But I know that Timur Civan has advocated using them for special effect purposes, ie., having the degradation serve an aesthetic purpose.
no glass = no infnity. only good for macro & close focus.
corrective optics allow to reach further away but degrade sharpness and clarity. still useable for video from f2.8 & getting better around f4-f5.6, forget about it for stills. will bloom like crazy as you dial anything wider than f1.8 on fast glass which kind of defeats using quality FD lenses with such adapter.
