Lens release button

what the hell are you carrying, i didn't even carry that on patrol in iraq and i had some major weapon systems in my hand on a regular occurence!

LMAO! Obviously lost in translation. I was refering to the combined weight of two rugby players, rapidly appropaching i.e. "bearing", preparing to score a "try". Seriously guys, this is the best laugh I've had in a loooong time! Cheers!

I can assure you I have a whole case of them upstairs. These are "New FD" but "Old FD" was the same in that respect.

You might be thinking of FL, not sure.

Still a noob after 30 years huh - still a yongster compared to some, I like it.

Hi Lester, I think Jon was applying a large amount of tongue to cheek in posting this. I remember the old FL breechlocks, and the introduction of release buttons on FD lenses, that were dismissed by the "old guard" as "novelty".

Ok... I got bored and decided to see if it was really true... turns out one of every ef&ef-s only amounted to 270.45lb (including the giant 1200mm). Add in every digital EOS (47.48lb) and the flash units (4.57lb) and that only still totals to 322.5lb. So unless if he's got 77.5lb worth of tripods or something, I'm totally clueless as to what other "Canon" weight can be added.

WOW! You must have been reeeeally bored! You forgot the numerous printer/copier/fax combos that Canon have done over the years, and don't forget the case to carry all that stuff would be huuuuge! This thread has made my Christmas guys, thank you all. Can we get this stickied?

Those damned decimal points keep dropping off.
Or he could be carrying his M-I-L on his back, I got rid of mine years ago.

Ermm, what's an "M-I--L.", Joe?

Yes, bored I was... while we're at it, might as well pack your entire house along with ya... only a couple tons worth of cement and wood n stuff... might give you a stiff shoulder after you're done, but heck, "there's nothing like home".

I can't work out a way of doing this with the EF without dropping something.

Any suggestions?

Any juggler can answer that one. You just have to arrange for the hang time to be long enough to finish the swap. I think the gravity on Titan might suffice...

To be honest I missed the FL's although I still have some old FD type ext tubes which were like Jon described (I had forgotten that), I think the New FD system came in in 1976 and my first SLR was a A-1 which would have been about 78.

I also have a second hand Ftb that I preferred to the flashy A-1 that came with an old FD 50/1.8 but I sold the that lens on.

So I probably am a noob to Jon if he remembers the old FD and FL's from new.

I don't mind though, I am getting creaky enough that anything than makes me sound a bit younger I will not object to.

I'll check the flight schedule....

R, FL and old FD had the silvery aluminum band which twisted to lock the lens in place; the lens proper didn't turn and there was no lens-release button required. It was later on that they went to the "bayonet-style" mount, where the whole exterior of the lens twisted (the rear lens plate remained fixed). The changeover came with the introduction of the AV-1 in 1979. I don't recall any third-party lenses that changed to the "bayonet-style" lens mount; they all stayed with the classic breech-lock.

Yes you are right; I never had much old FD kit and had forgotten. The removal action could still be one handed though (I tried again today jog the brain).

With the EF system I have tried wrapping my hand around the lens and depressing the release button with the knuckle or such but can’t get this to work for me. The larger diameter of EF lenses makes my grip on the lens less secure also (my hands are not the large).

I think the change over was 76 according to Canon, I think I had an A-1 by about 78.

Happy days! But I have to say I have taken more and better shots with the new kit, particularly in macro and wildlife - the freedom from film cost in part and being able to afford better quality lenses etc.

Obviously, but it did make me laugh, no doubt i read this thread after a few ales and was very tired at Xmas, hope it was as good for everyone else as it was for me.

NOOB! Real FD lenses don't have a lens release button; you have to twist the aluminum breech-lock ring (only). Grab the lens by the ring; twist off and remove. Holding other lens by ring, press it on; the ring twists about 2-3 degrees (enough for a loose attachment); re-position hand and tighten the rest of the way.

If I had to stop and think about how I change lenses on the EOS line, I wouldn't be able to do it. But then, I don't change lenses; I change cameras most of the time.

Yeah, Jon! Those are the FD lenses I remember.
