fred_wilson1 Posted August 7, 2007 Share Posted August 7, 2007 I am waiting on a used Canon FT QL I bought on Ebay and while looking at lenses to buy for it I have noted that it uses FL mount lenses. Will FD mount lenses also work on this camera? Link to comment Share on other sites More sharing options...
james_lai Posted August 7, 2007 Share Posted August 7, 2007 Yes, FD lenses are backward compatible with FL-mount cameras. Link to comment Share on other sites More sharing options...
awahlster Posted August 7, 2007 Share Posted August 7, 2007 Yes but will not have the stop down switch on the lens and will have to use the stop down metering controls on the body of the camera. Link to comment Share on other sites More sharing options...
steven_clark Posted August 8, 2007 Share Posted August 8, 2007 The "A" mode on the aperture ring will not work so the aperture will need to be set manually and you should avoid trying to mount the lens with it in "A". I'm not sure what Mark means, but then again I've never played with an FL lens. If FL lenses have manual stopdowns (probably for metering) FD lenses do not. They are either automatic stopdown only, or in some cases you might be able to lock the stopdown lever in the stopped position and use it stopped down all the time.

michael_bizon Posted August 8, 2007 Share Posted August 8, 2007 from the book: The Canon Manual, Paul Jones 1976 "the Canon FT and FTb are simplified versions of the Canon F-1 (first model). The main differences are that the finder system is not interchangeable, the camera back cannot be replaced by the long-length roll film magazine, and the motor drive cannot be attached. The highest shutter speed is 1/1000 sec. instead of 1/2000 sec. The difference between the Canon FT and FTb is the way the metering system works. The FT provides stopped-down metering with FL lenses, while the FTb does this at full aperture when FD lenses are mounted to the camera, but stopped-down metering only when FL series lenses are attached. In both cases, of course, the diaphragm closes automatically to the premetered f/stop. When R series lenses are used the metering is done with stopped- down diaphragm and, after reopening the diaphragm for focusing, the diaphragm has to be closed down again manually to the premetered f/stop.. " in the lens section of the same book; " there are certain markings engraved on the mounting ring of the front element of the lenses such as, FL, FD, or R, and these markings obviously bear some significance. Though any lens with any marking can be attached to any Canon SLR camera, the manner in which the through-the-lens metering system operates and couples to the diaphragm is different. Lenses with an FD marking provide full-aperture metering coupled to the automatic diaphragm when mounted to cameras featuring the FD mount (Canon F-1 and FTb) note: book is from '76)) Lenses with an FL marking provide stopped-down metering coupled to the automatic diaphragm when mounted to any Canon SLR camera with a through-the-lens metering system. Lenses with an R marking can be used on any SLR camera for stopped-down metering, but the diaphragm has to be set manually after the metering. however, R series lenses with a diaphragm pin under the barrel work automatically with the Canon Slr's, which do feature a through-the -lens metering system." Kind of lengthy, but I hope this helps, good luck! Link to comment Share on other sites More sharing options...

fred_wilson1 Posted August 8, 2007 Author Share Posted August 8, 2007 Thanks all. This has been a great help and will make my shooting experience better. I still haven't recieved the camera, but will let you all know how it works out for me. fred Link to comment Share on other sites More sharing options...
User_502260 Posted August 8, 2007 Share Posted August 8, 2007 The FT and FTb are not simplified versions of the Canon F-1. The FT was introduced in 1966. The F-1 was not available until 1971. The FT and FTb have much more incommon with each other than either one has with the F-1. The F-1 has a titanium foil horizontal shutter with a top speed of 1/2000. The FT and FTb have cloth horizontal shutters with top speeds of 1/1000. The wind mechanism of the F-1 is much sturdier than those of the FT or FTb. I like the FT and the first version of the FTb better than the FTbN but I refer my F-1 bodies to either of them. Link to comment Share on other sites More sharing options...
