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????

I do exactly as described but if you loosen the screw too much, the collar opens even without pulling out the screw to unlock it. And when you lock the collar on and turn the screw to tighten it, it still is likely to turn on a tripod. It is simply the worst design I’ve ever encountered and I’ve had many telephotos.

I've noticed this on my lens as well. It's not terrible. But, when using a tripod, I don't want the barrel slipping on me. I have the RF70-200 and locking ring is rock solid. I just sent a repair request. Hopefully, Canon can address this is short order.

I reported this very issue to Canon. Since mine was still under warranty, they sent me a replacement which is rock solid!

Is it the same design?

On visual inspection, I couldn't tell them apart. But, something is obviously different as now the ring will not turn when locked even when I try. It looks like just a bad one got through initially.

What method did you use to make this happen? I don’t want to do a full warranty claim where they ask me to send the whole lens back when it’s obviously just the collar that needs to be replaced. Thanks.

Once I submitted the support request form, an agent sent me an email asking for the following proof of purchase:

1. Retailer name

2. Retailer address or store #

3. Date purchased

4. Specific product purchased: Canon RF 100-500mm f/4.5-7.1L IS USM Lens

Since I store copies of my receipts with my registered gear on canon.com, shooting them a copy of the receipt was simple.

5. Purchase price: $2899.00

I tried what you did—an email support request. I got treated differently. They want me to send the whole lens in. And I’d have to pay for shipping to Canon with insurance. I wish they’d just send me a replacement collar like they did for you. I even offered to send video showing the problem.

[hugebob]

Did you purchase that Canon extended protection plan? Maybe that's the difference.

No. I didn’t have the CarePAK thing. But I have had further communication with them and at least they are now sending me a prepaid UPS label.
