Meike MK-RF-AF1 13mm + 18mm Metal AF Full Frame Macro Extension Tube Adapter Ring Kit for EOS-R Series Cameras RF Mount Cameras EOS-R EOS-RP

I was looking for an accessory to my EOS R system to get some better macro shots. The extension tubes worked perfectly. The macro kit is well built and easy to use. I was so happy to see the Auto Focus worked great with the rings. It makes focusing so much easier. One of the features on the EOS R is the focus guide when you have AF turned off on the lens. It's a great feature to use for macro photography along with the focus peaking. Because the rings have the contacts built-in, the focus system on the EOS R works without fail. I tried the rings with my 24-70 MK ii and my 100 mm macro lens that are both EF with the EF to RF adapter and it was like using a native lens. I also used an RF 50mm and it was great too. If you are looking to make any lens a macro ability lens, then these tubes are perfect. They make the minimum focus distance less and add some mm to your focal range. So adding an 11mm ring to my 100mm macro makes it 111mm and also allows me to focus closer. I would highly suggest giving these rings a chance for getting some beautiful macro photography. They are affordable and built very well. I love to buy accessories to try with my camera to have some fun with and these were a ton of fun to use. It's so encouraging to see more companies build products to use with the new RF lens mount. I can't wait to see new things come out for the RF system soon.

Pretty happy with these extenders. Works great on my RF Lenses, and even great with a EF-RF Converter. No issues with compatibility on camera bodies (Tested with R6mII, R8,R10, RP) or various lenses. AF works perfectly, and I was able to consistent autofocus when needed. The build qualities decent, the extenders are light, and stackable if you want. Really no complaints about them. They do what their suppose to do at a decent cost.

I used the Meike MK-RF-AF1 13mm + 18mm Extension Tube Kit on a Canon R6 with the RF 24-70mm f/2.8, and the results met expectations for macro work. The tubes preserve full electronic communication, including AF and aperture control, which is a big win. The combo performed beautifully for close-up flower photography, letting me get surprisingly close while maintaining sharpness and control. Build quality is solid—metal mounts feel durable and snug. However, the 11mm tube has a sticky release latch, particularly when mounted to lenses like the RF 50mm f/1.2 and 24-70mm f/2.8. It takes some finesse (and patience) to detach, which could be frustrating in fast-paced shooting environments, and downright nerve racking when you have a $25 tube stuck to a $1600 lens. Overall, it’s a good value option for anyone exploring macro work with RF glass.

I wanted a fully functional extension tube ring set for my RF cameras, and this popped up on my "suggestions". First to note, there are only two rings. Other sets for my full frame EOS cameras had 3 rings. These rings, like other inexpensive brands in past purchases, are lower in price than the camera manufacturer and higher end brands. When I received them, they were excellent build quality and they work. No just juggling just right for the rings, and for the planets to align just right - they consistently work. I will be buying a second set soon.

Results 31mm combined extension. AF struggled with R5 with 50/1.8 and 100-500 rf lenses but worked reasonably well with 24-240 rf. Achieved max magnification of 0.95x at 35 mm with 24-240, however unusable because lens touching object to focus; with the same lens magnification was .52 at 240 vs .26 without extension. Was most usable with 50/1.8 with MF at max magnification of 0.82x and reasonable focusing distance. Max magnification with the 100-500 was 0.5x, from .33x without the tube. Mechanically felt OK, but did not lock the 100-500 lens, so would not recommend carrying the camera with the extension and a large lens.

These really work well. I’m so surprised that they transmit the aperture and focus signals to the lens from the body (considering Canon’s Third Party stance for RF mount). The mount is solid and they do the job.

They fit without jamming and snap in with ease. Just a bit of slop when locked in. I had one issue where I didn't click together far enough, but now I double check and issue free. The lock/release is a bit small but functional. Overall, they work and are a good value. (EOS R and a bunch of RF lenses) - Update: Still working just fine. But, the caps don't stay on in storage. There are no clicks or stops to keep them attached.

I have never had a problem with Canon or Nikon-manufactured extension tubes over 40 years. Unfortunately I needed to buy a non-Canon product because Canon does not (yet) make extension tubes for RF mount lenses. Hence I went with Meike due to reviews. The tubes worked well initially, but then started to intermittently fail on a trip, not communicating with the camera to allow me to even take a picture. I had to reset the camera by removing the battery each time this happened. I found out that I simply cannot rely on these tubes. For anyone interested in more detail: I purchased two sets to get 62mm extension. After the first tube failure I taped all the tubes together so they wouldn’t jiggle, and this seemed to work — until it didn’t. After the second failure I tested all the tubes and found one that simply no longer transmitted anything, so I used the remaining three tubes, and this seemed to work — until it didn’t. Then I used just one 13mm tube, and this has worked for now, but I know I can’t rely on it simply because it was constructed the same way as the other tubes, and I can’t rely on the construction methodology. This all happened on a trip to Panama, so I did lose shots. When I returned I took apart the tube that completely failed so as to look at the construction: The way the movable pin works is simple & straightforward: a pin pushes against a spring when the lens is attached, so that the spring pushes against the static connector on the other side. I don’t see a way to figure out why this failed, but one reason could be that the tiny springs may not be of the best quality. There shouldn't be a problem with the fixed connectors since the camera has the spring-activated connections, and they perform flawlessly. And there’s never been an issue with the camera-lens connection without the extension tubes. My next attempt is to try Fotodiox, which at least is a U.S. company that (although the tubes are still made in China) I would hope ensures better quality control over the products they distribute.

Tutto perfetto

De extentieset om van de RF 24, 35 en 85 mm lens een echte macro lens te maken

Muito ruim.Descrevem como compativel em qualquer câmera Canon EOS mas não serviu na minha.Péssimo.

The Meiki extension tubes are well build and with all electric contacs they give full lens functionality including AF. There is no slack in the connections between tubes and between a tube and a lens. The price is very reasonable. I use the extension tubes in connection with a Canon RF 50 mm f1.8 lens and together with JJC Film Digitizer Adapter to digitize negatives. With both extension tubes in use you get approx. 0,75 x enlargement. You could probably push this magnification a bit more, but you also need some leeway for autofocus to work. So I would have liked to have had three rings in a set to achieve 1:1 magnification. Please note that for Canon the rings provide a few millimeters of extra distance compared to, for example, the rings intended for Sony. I can mention that I mount the camera and the JJC adapter on an OTraki Flash Rail. With a little adjustment + some creativity I get the camera and the JJC unit to be at the same height. It works fine.

Sprawdziłem działanie na Canon EOS R10, działa doskonale zwłaszcza z obiektywem 35mm i 50mm. Działa również z obiektywem RF 24-105mm z AF. Zdjęcia zrobiłem w kilku konfiguracjach (3). Trzeba tylko się trzymać ściśle zasad do fotografii macro.
