Extension tubes on RF Lenses

[FrenchFry]

Hi!
Would those of you who have used extension tubes on your RF bodies and lenses please share your experience?
What brand of extension tube did you use? What length of extension tube? What lenses did you use them on? How did it go? Any issues with AF, image quality, or other challenges/concerns?
Do you have any sample images that you would like to share?
Thanks for your feedback!

i just bought:

Meike MK-RF-AF1 13mm and 18mm Extension Tubes for Canon RF​

they both fit on RF 35mm f/1.8 macro IS STM.

no issues but i'm no expert. At 35mm with 1.39x it is close to subject, lighting can be difficult. I use manual focus all the time.

Thank you for sharing your experience!
Do you find yourself using the 13mm or 18mm more? Do you ever stack them?

I stack for small insects. Bigger ones are scared of my minimum focus distance.

I have extension tubes for my EF lenses. And, I just bought an RF 100 f/2.8 macro. But, I'm wondering why? I already have many lenses with focal length 100 mm. For macro purposes, what is the benefit of a $1000 lens vs. $150 extension tubes attached to a 50mm good prime?

Seems like a waste of money.
In the example where he used the extension tube to focus on the droplet, the focus point was a millimeter or two behind where it was with the macro lens. This may explain the tiny difference on the droplet? Otherwise, extension tube is essentially the equivalent in everything except size, weight and price?

I've used a set of off brand extension tubes to get closer focusing with my 600mm f4. No issues
