For those of you that have the EF 24-70mm F2.8L, do you use and turn the zoom lock switch off and on? None of my other Canon lenses has this feature and I'm wondering how useful it is. Thanks.

I use it when I store the lens or when I will be walking around for a long period to time and don't want the lens to creep downward (although it really does not easily).

Don't think of it most of the time. I suppose it is useful sometimes.

You must be referring to one of the new model 24-70s. The original model 24-70 f/2.8L (sometimes referred to as "the brick" and which is my favorite lens for EOS cameras) does not have such a switch.

Actually, that's a good point - lens creep (wish my 24-105 had the lock switch!).

Yes, I meant the new model II.

I was thinking "10 years and I never noticed it had one!"

I think I used it once. You know, to see if it worked. Then, I pulled my camera out of the bag and tried to zoom with it still locked. I thought my lens was broken when it did not zoom, and felt like a dolt when I realized the lock was still on. Have not used it again.

I had the same initial experience.

Haven't had mine long, but haven't used it yet (except to frustrate myself the first time I tried to zoom). I don't think it will be useful unless I go bungee jumping with the lens. Maybe when the lens is older or has 12 stacked filters.

If I ever sell it for some reason, I'll lock it then to hopefully give the next owner the same initial awkward frustration (also for shipping more safely).

I have a very tight camera bag, if the lens lock is NOT on then it pulls the lens out to 70mm when I pull the camera with lens out of the bag..

I always set it when I am done shooting for the day before putting it back into the bag. all lenses will get looser over time, and I am just hoping this would slow down the process a little. probably not though since the amount of pulling in and out while not in use is probably not significant to how much there is during use. guess it's a mental thing.

I forgot it was even on thereā€¦ which means I have never used it. I would probably forget and think the lens was broken and panic. Hopefully after reading about WayneHawn's experience, I will remember all this in the back of my mind so I will not panic :)


I want lenses more than diamonds.
