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

These extension tubes work well, feel well made and solid. With my R6 Mk III (a full frame sensor) the auto-focus works well. With both tubes attached I am getting a true macro enlargement (1:1) with my Canon 24-105 set to 50mm. I photographed a ruler and the frame was filled from 0 - 35mm. Set to 105mm the enlargement is not quite so great (the ruler width was 40mm in the viewfinder) but it is easier to get light to the subject without casting a shadow. All in all I am very happy with these, especially at the price.

I had waited in the hope that Canon would make their own RF extension tubes but I needed a small one for a specific task to use with an RF 85mm f2 Macro lens and so I decided that this pair of Meike ones would be fine. I am reasonably impressed with the build quality and the electronics all seem to work fine. There's no glass so as long as they are straight and can communicate between lenses and bodies (R5 MkII in my case) then they are perfect for the job. I have only used them for one job and, apart from doing some testing beforehand, haven't really given them a full workout but everything so far points to a very good buy. If Canon ever make their own I might be tempted but if these Meike ones prove to be durable then I don't see any reason to do so in any hurry.

These meike canon-rf-fit extension rings work well with my Canon R7. They are slightly looser than I would like, but work well.

Combined it with my RF100-400 and my 2x converter to get some pretty good closeup shots (red common darter photo). Also tried it with 200-800 and 2x and it was pretty good (green southern hawker), but needed more extension to focus close enough. A set of 3 tubes with a 24mm or so tube would have been better.

Initial impression is good. Tested and they work fine. There is a small amount of rotational movement if you try and twist the lens when one or both extension tubes are attached, but not enough to cause connection problems. The tubes are metal and plastic construction. I wouldn't be too comfortable hanging a heavy lens off them, but most lenses should be OK. The weather seal was a nice surprise. But I don't think there is a seal at the lens release button.

Does exactly what it's supposed to. full autofocus compatibility. end caps are a little loose, but that's not an issue. No image quality loss because therre's no glasss, they're just spacers.

It works but most of the pictures will come out blurry. You get what you pay and i wanted to test close up photography and for the price it is worth it. Just be aware of the out-of-focus issue.

Using them with a Canon R100 + 26-105 Canon RF zoom lens. They really look very well made, with a "red ring" on each - most impressive. The 12 pins make a "noisy' entry when being attached, compared a Canon lens. Repeatedly connected them to each other to try to improve things. However, everything works as intended - focussing and metering. The autofocus works best when the lens is fully zoomed out to 105mm - less so and it struggles. With both tubes in place image size doubles; obviously less so singly. I think a brightly lit subject may be the order of the day. No serious photos to review, yet.

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.

molto divertente, qualità prezzo incredibile, funziona molto bene, i contatti ti permettono di utilizzare benissimo i diaframmi, usato anche con ottiche pesanti, acciaio inox perfettamente funzionante.

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.

Bague allonge qui fonctionne très bien. L'AF fonctionne si vous souhaitez l'utiliser
