Canon 2972C002 overview

  • 1Description

Extending the range of compatible lenses, the Canon Control Ring Mount Adapter EF-EOS R is a unique lens adapter designed for attaching any EF or EF-S-mount lens to the EOS R mirrorless digital camera. This sophisticated adapter incorporates a customizable Control Ring, the same as that on native RF-mount lenses, for intuitively adjusting exposure settings, such as ISO, aperture, and exposure compensation. This ring provides tactile feedback when being turned, making it easy to recognize and control your settings adjustments. It also retains full autofocus and image stabilization capabilities and contains no optical components, thereby maintaining the original optical quality of the mounted lens. Additionally, it is dust- and water-resistant, making it suitable for use in harsh weather conditions.

    Canon 2972C002 reviews

    Control Ring Mount Adapter EF-EOS R is rated 5.0 out of 5 by 7.
    Rated 5 out of 5 by from Brings EF lenses into the age of the R There are many reasons that the Canon EOS R makes EF lenses perform better but to keep my review short and sweet, the Canon Control Ring Mount Adapter ER-EOS R is what brings the transformation to life. I buy one adapter for each of my EF lenses as I want to keep the fiddling with equipment to a minimum... Each of my EF lenses is now and RF lens, plain and simple... each adapter STAYS with its own lens... I have sold all of my pentaprism cameras and not looking back... The EOS R is replacing everything from the 1DX on down... Thanks Canon for a great new system and for integrating the EF line of lenses.

    Rated 5 out of 5 by from Does what its meant to This adapter is built well, you can feel when you haggle it that it is a solid peice. Because the EOS R doesnt have a control wheel on the back together with the d-pad, this makes up for it well. I set it to control apeture, main dial controls shutter, and the secondary dial controls ISO, so Ive got the main three controls all adjustable directly with a dial. Comes in a nice pouch, but I dont really have any use for it - the adaptor lives on my camera. I did manage to get $50 off, from the nice b&h sales rep that paved my order, presumably because I bright it together with the EOS R.

    Rated 5 out of 5 by from Brings control ring functionality to EF and EFS lenses The Canon EF to EOS R control ring lens adapter instantly brings EOS R control ring functionality to EF and EFS lenses. Built like a tank, has excellent sealing for adherence to Canons precise fit of EOS R camera to lenses. Canon has done all of the work and that means this adapter leaves the photographer free to get the images they want, while the adapter requires no additional attention other than bringing the EOS Rs phenomenal ability to let you adjust while seeing the result before you take the picture. Highly recommended.

    Rated 5 out of 5 by from Buy this, disabled Multi-Function Bar, havent looked back Build quality: excellent! It feels as well built as the EOS R body. It uses the new beefy RF bottom caps. I have a 100-400 f/4.5-5.6L and a 1.4x teleconverter mounted to this, on a Peak strap walking around a track for six hours and it didnt budge. It might as well just be part of the body when attached. Functionality: the standard one is probably all you need. With the customization possibilities of the EOS R, on the body you have up to three adjusters. I went with the Control Ring option because I was concerned about the multi-function bars usefulness, and Im glad I did. My hands are big enough that the mf bar hinders my camera usage by accidentally touching it all the time. I disabled it and use the control ring now for functions you can assign there. Compatibility: this has worked with EVERY EF lens I have attached to it. This includes third-party lenses like my Sigma 50 1.4 Art. I would say that compared to my old camera, a 6D, the lens focuses faster. With that 100-400 and 1.4x attached, it was moving a lot of glass very fast to lock onto Formula 1 cars speeding by, and it exceeded my expectations. My 40mm 2.8 pancake with a stepping motor focus system works great on here.  Weird thing: the camera sets the focus to infinity on the lens when you turn it off. Its a nice feature with prime glass that may move outside of the body to focus, like the 40mm 2.8. Single downside: because your old lenses arent RF lenses, you lose the 100% vertical AF coverage youd have otherwise. You still have 88% of the frame to set AF points to. I never once have needed any more. The EOS R system is a remarkable start for Canons serious entry into mirrorless. Unless youre dropping big money for the new RF lenses to replace EF glass, youll need an adapter. I figured spend $100 more and get an extra control option, but I dont think you can go wrong with any of the options. Its built great, communicates with EF lenses flawlessly, and is actually pretty inexpensive by Canon standards.

    Rated 5 out of 5 by from Its good Works as it should. I still find myself double thinking when actually using the ring but I think that is me just needing to get use to it. I have it set to ISO since I dont want change iso to be a 2 step process.
