JJC Canon RF Mount Auto Focus Automatic Extension Tubes, Macro Photography Adapter for Canon Mirorless Camera EOS R R5 R6 Ra RP, Closeup Portrait, Brass Mount Gilt Metal Contact, 11mm + 16mm Tube

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.

They work as they should.

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.

Metal moutn and tube. Well made. Works.

They do what they were designed to do. No issues.

Product works as designed
