Canon FD Mount

Hi All,

Forum newbie here and just in the process of getting back into using my old cameras again.

I recently resurrected my old Canon T50 and was looking to add to the 50mm standard lens that it came with. As such I had a look on the old faithful fleebay and found a Miranda 35-70mm 1:3.5-4.5 MC lens with an FD mount. Given the T50 has an FD mount, I just presumed that it would be correct but it turns out that the mount on the Miranda lens looks the same as the 'male' type mount that's actually on the camera but not the same as the 'female' mount on the original 50mm lens, if that makes sense?

I can't post links yet to show the different mounts unfortunately.

It seems my limited knowledge has scuppered me, do I need to obtain an adapter or have I just wasted by cash?

Many thanks in advance.

Hi, welcome to the forum. Well done for trying to resurrect your love of film.

Could yours be the Miranda 35-70 lens sold a few days ago for £6.52? I found that listing, and compared it to my FD lens and body... sorry you have been sold a pup, that's not an FD mount. No idea what it might be.

There is some great genuine Canon glass out there. I picked up a FD 35-70mm f/4 that was in great nick, but I can't remember how much. Also got a FD 28mm and FD 135mm both for £28 each.

Good luck!
 
It could be the breach lock the earlier FD used. You will need the so called NewFD for your later T50.

I don't think that is the answer - but happy to be corrected. My understanding is that the breechlock just allowed the lens to not have to be rotated, the breechlock rotated on the lens. The physical mount was the same.

As the OP said, the "mount on the Miranda lens looks the same as the 'male' type mount that's actually on the camera", so the lens could never fit on an FD camera. (If I found the correct listing).

Well, you're quite possibly right. I haven't seen the mount, so I can only surmise.
 
Just a quick post to confirm that the breech lock and the newer FD lenses all have the same mount.
 
My thanks and appreciate all the comments folks -

These are the mounts specifically -

This is a T90 body but the FD (male) mount on my T50 is exactly the same

This is the 50mm 'female' FD lens that fits the T50

and this is the Miranda lens I just received

As you can see it's similar (male) to what's on the body of the T50 and I've seen other body mounts that this lens would seem to be compatible with but I presume this is a MC mount and not an FD mount as was described?

... and yes @Boots that probably was the same one you saw, again showing my ignorance and just taking the descriptions word for it. Luckily it wasn't a huge amount of money.

Those FD pictures look exactly as I would expect to see.

I think you could usefully contact the vendor to point out their mistake. Or, in view of the amount of money, just give up! It ain't going to fit.
 
If I was guessing I would say that Miranda lens was Nikon F.
Canon FD lenses have a silver button which you press to release it from the camera and then turn the whole lens anti clockwise to remove. Third party FD lenses (and very old Canon ones) have a collar at the rear with a red dot on it. You line the red dot with the one on the camera and turn the collar, not the whole lens. Both work, just depends what you are looking for.

He actually is right. The breechlock mount on FD lenses have you putting the lens against the body and then you rotate the ring which locks the lens onot the body. The lens does not rotate as you mount it. FD lenses you have to align the red dot to that on the body and then rotate the whole lens and then it will click into place.

Yes, I have both. I've never really understood the merits of a breach lock, I must admit.

No wear on the surfaces being brought into contact with each other and it is mechanically less complex than the later New FD implementation which jumps through some hoops to turn the mount into one that operates like a bayonet mount.

Ah, of course. That would make sense.
 
Downside of the breechlock is that it’s harder and riskier to change a lens one-handed
