mcoplusEXT-RF-M Metal Auto Focus Macro Extension Tube Set(12mm+20mm) Fit Canon RF Mount EOS-R/EOS R5/EOS R6/EOS-RP Lens and Camera Body

Fits like a glove to my canon eos r, takes a little experimentation to get the picture you want . When you get the hang the fun is just getting started. Each extension tube is sturdy and well made. Easy to put on and take off. You will be happy you picked these up and it will open up a whole new world to you

5 stars for functionality. Once they’re mounted on the camera, they do what they’re supposed to do. I get pretty good decreases in MFD with both native RF lenses and EF lenses with the extension tubes+ adapter.The reason I give them 4 stars instead of 5 is the quality. I expected then to be cheaply made but the included lens caps don’t stay on the extension tubes when I’m not using then. I screw the cap on and it’s very loose and just falls off. However, the quality of the tubes during use is fine, haven’t noticed any negatives.

You’d think this would be made out of aluminum and steel. Nope, it’s all plastic other than the few screws that hold it together. It’s unsafe to put a valuable lens on a junk plastic.The fit of the parts is sloppy. Which is what you get with plastic. Don’t waste your time/money.

Purchased these for use with Canon EOS RP. Took a bit to figure out settings to change in camera to get adapters to work...once done they work fine!You need to enable shutter release w/out lens in custom settings.

Overall these work as expected. My only slight complaint is that the caps that come with it do not fit tightly and constantly fall off in my bag. The price is a little steep to have this issue.

I have used these lens for Marco photos ... A very little drop in sharpness ... I have enjoyed using these lens

I received this set without end caps. Both tubes are wet and sticky on the mount - silver parts. See the pictures for yourself. This looks like a used item too because the box was already torn.

Works great with my Canon R
