How to losoen tripod mount nut on my canon lens

limvo05 — Mon, 22 Jun 2020 05:55:23 GMT

All,

I was wondering if anyone here ran into this issue before, and if so what did you do to get out it of it?

I accidentally tighten the tripod mount nut on my canon lens too tight now, now I can't even get it to loosen.

Thanks.

Just to be clear, I am talking about the colar on the lens. The one that lets you loosen to rotate the lens. Thanks.

Wrap a single layer of cloth around the knob and grip firmly with a pair of pliers.

A drop of penetrating oil on the bolt may help as well. Just don't let any of the oil get on the lens itself.

I tried both. A squirt of WD40 as well using a tie-string but no luck. There isn't a lock or some button that I should be depressing in order to loosen the knob right?

Thanks.

I think this might be the problem https://www.youtube.com/watch?v=LvgRoUHA_VM

Now, I need to figure out how to undo the screw as one of it kind of messed up.

Wondering if it would be possible to find a replacement screw once I manage to get the old one off the lens? Is it possible to find a replacement tripod mount for old lens?

Thanks.

It would be helpful if you told us the model of the lens.

Failing that, there are many 3rd party lens mounts avialable on the web - try eBay for example...

It's the Canon 300 F2.8 IS.

FYI. I've reached out to Canon Support, they told me to try to unlock it by hands LOL!

Bought a new tiny screw driver, combined it with ordinary elastic band, applied slow torque as I turned the screw, I was able to remove the stripped screw, and ordered a new screw from Canon. A new screw cost 24 cents. Shipping $7 LOL!

Anyway, very happy that I was able to fix the tripod collar issue. The bad news is, anyone else want to buy the same screw for this lens, you can have them for $100 as I have bought the last of it from Canon LOL.

"... I have bought the last of it from Canon LOL."

You may have bought the last one from Canon but not the last screw. However you might be close to the price!

The moral of the story was, the screw costs 24 cents, and the shipping cost $7. How on earth do you justify for the $7 shipping cost? I am curious how big a bag or box the screw is being shipped in?

Are you serious? This is what happened.

Mr. Scott reported that the transporters were down. So, they had to hire someone to bring it to you. That person had to stop off, and fill their gas tank. Someone had to pay for the vehicle the person used. Someone had to register and insure the vehicle, too.

I forgot to mention that they had to pay someone to purchase the screw. Pay someone to stock the part on a shelf. Pay someone to pull it off the shelf. Pay someone to box it up, and put postage on it.

Oh, yeah. They had to pay someone to process your order payment Thank-you, come again!

You justify if by considering how much time and gasoline you would expend in going out and buying it locally. The 24¢ price of the screw is irrelevant. It might be in your interest to pay the $7 shipping charge, even if the screw were free.

I agree it is ridiculous. 7 bucks to drop a screw in a mailing envelope is outrageous. It is probably an arbitrary minimum change. I garrantee it goes higher on bigger orders
