Thanks for the suggestion, I will have to do some research on that particular lens. First time I've heard of it. Can I only get the lens and adapter from ebay? I dont use ebay coz of some dodgy 'sellers'.
Yes, as scrappydog indicated, Ed Mika is the only source for this adapter (which has no glass optics -- it's purely an engineered brass replacement for the FL 55mm's breach lock mount). He is currently only selling on eBay. Ed is an excellent seller and will do everything to make sure you get your adapter in a timely manner and provide all the support you'll ever need in getting it installed and functioning. It's really quite fast and easy to adapt the lens and it is entirely reversible if you want to take the lens back to its original condition.
Other adapters for old Canon glass usually involve optics which effectively slow the lens down. Some adapters require you to permanently alter the lens making it thereafter unusable as originally intended. All of Ed's adapters are non-permanent and non-altering, involve no optics, and have microchips providing autofocus confirmation and EXIF data back to the camera body.
I'm a big fan and now have several old lenses with Ed's converters. The FL 55mm was my first. Having a lens that can shoot at f/1.2 is a huge advantage -- it's letting in about 50% more light than f/1.4 and about six times more light than f/2.8 so you can do available light interiors and night shots. Plus at that wide an aperture you can get super-shallow depth of field. It's an 88mm equivalent on a crop body like the 7D so it's a great portrait lens, too.
It's an awful lot of bang for not a lot of bucks. And it's just a fun and versatile lens.
