Hate the RF100-500 Lens Collar

[tangogal]

Does anyone else hate the lens collar on the RF100-500 lens? If it's somewhat loose, it frequently breaks open potentially spilling the lens to the ground. It is very hard to tighten enough so that it doesn't slip around when on a tripod. I have owned many of Canon's telephotos before I switched to the mirrorless system. I never had a problem with their lens collars. What genius in engineering came up with this awful lens collar design????

That's still odd. They shouldn't need the lens. Just sending you a new collar should be enough and it would save them all this effort.

Anyone having issues with their lens collar should contact Canon.  When the ring ends engage, you have to press gently when you start turning (tightening) the retention screw.  Tighten firmly.  It will be snug.  Don't turn it further. Don't apply excessive force.  Perform a visual inspection before each use.

The thumb screw does not stay loose or spin freely.  If your lens rotates when tightened, your collar is damaged or has a manufacturing defect.  Contact Canon.  The collar is covered under warranty or CarePak.  If not, its about $255.  If your lens falls and your camera is attached to it, you are going to be out a lot more than replacing a faulty collar.  >> Contact Canon.

This is what I have finally done. My lens is no longer under warranty, so the lens collar is around $220. I am having Canon send me a new one. If it does not work any better than the original lens collar, they said I can return the new one within 14 days and get a refund. I am taking it on a trip where I will be using this lens on a gimbal, and I can't have it slipping. Hope the new one is better. It is a really awful design. Had they used the same kind of collar that was on my EF lenses like the 70-200 and 100-400 and 300 prime, I would not have had this problem nor had to pay this amount for a replacement.

Greetings,

What was the outcome?

[tangogal]

The new one works much better but I still wish they would go back to the old design.

Appreciate the feedback.

I completely agree with Tangogal, it's a stupid design. You always have to check and doublecheck when you put it on. As a pro I don't always have time for that, and I want to concentrate on taking photo's, not on equipment.

I have the same issue, took my lens for a service last week, and requested a repair of the loose collar, got the lens back and the collar was loose again (unable to tighten enough for the lens not to turn in the collar). Contacted Canon telephonically and they replaced the collar with a new one. One outing later and the lens is slipping in the new collar, again unable to tighten the lens in the collar. I'm using the equipment to earn a living and can not afford for this to happen on location. Will contact Canon again in the morning and hear what they have to say.

I am sorry the replacement was just as bad. I had to purchase a replacement for about $200. So far it is holding but I worry every time I use it.

Canon replaced mine under warranty a few months ago. The replacement "broke" just the other day. No big deal: loosen the lock for a portrait view and tighten. Thereafter, the lens continues to move even when the lock is tightened.
