JJC Automatic Extension Tube for Canon RF Mount
JJC AET-CRFII Automatic Extension Tube for Canon Mirorless Camera EOS R / R5/ RF, designed for macro photography and allows your lens to focus closer than its normal minimum focus distance.
By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created.
The extension tubes can be used individually or attached together to achieve your desired focusing result. These tubes are fully automatic tubes, so they are able to communicate all electronic functions from lens to camera including auto focus and auto exposure.
The extension tubes have no optical elements so they will not degrade the quality of your lenses.

My 2nd set just arrived via Prime today.I used a 100mm inexpensive lens with two of these sets (2x16 +2X11) for 54 mm of extension tube.The electronic pass through works great. I am very pleased.I wonder if an L lens would do any better(?).very happy to recommend these.

I wish a longer tube was available, to give closer focusing with the RF 800 f/11, but these do work. I just can't get as closeup as I'd like.

This extension tube(s) was perfect for my Canon EOS R for doing macro captures.

I attempted to use this with several lenses, the autofocus worked intermittently and was not reliable enough to consider this product usable. The build seemed solid, The finish seems quality, but he functionality was not there in my experience. Item is inaccurately described here on Amazon, i'll be returning it.
