Canon FL lenses

Does anybody know if Canon FL lenses can be adapted to L-mount? I saw something on the Internet that FL lenses are hard to adapt to other systems due to a different flange range and focusing to infinity becomes impossible. FD-mount lenses should work well?

Not a major issue but an FL tele fluorite lens is available locally at a low cost. Back many years this was the most expensive lens offered by  Canon.

Seems to be ok.

FL and FD is absolutely the same concerning mount and flange distance. The difference is in coupling used for aperture control and readout on Canon cameras - you don't use this anyway if you adapt. Any FD adaptor will also accept FL lenses.

A couple of years ago I used a FD lenses with a FD to M Adapter on the Leica M240 regularly. Later I tried this in combination with the M to L-Mount adapter and I think this also worked. Flange distance seems to be no issure.

Many thanks. The info I found on the Internet was clearly not correct.

...or simply dated back to the era before mirrorless systems (~ 2009). The internet has been around for several decades.

When viewing had to be done via an SLR mirror, then yes, Canon's mounts were the shortest, and its lenses would not fit on other bodies and focus to infinity.

Mirrorless has subtracted about 1-2cms from the SLR mount depths of yesterday, so there is far more compatability. Even M lenses can work on an SL/ Sony/Fuji (but could not on any SLR).

And if you ever have any other Canon cravings - yes, the R (1959), FL (1964) and FD (1970) SLR lenses all used the same basic breech-mount distance. The difference were in things like stop-down vs. wide-open metering.

I have a genuine Canon Lens Mount Converter B which converts FD/FL lenses to LTM (Leica screw). I've never used it as it was given to me by a friend who found it in a load of stuff he had. But it would be easy to add an LTM to M adapter and then fit it to an L mount via an M to L adapter. So the answer is yes it can be done and relatively simply.
