3 reviews for Canon EOS R + EF-EOS R Adapter

  1. Alfie Burke

    My first “mirror” after many years of using Canon DSLRs. The undoubted advantage is the size and compactness and ergonomics, which is quite good, although different than in the case of SLRs. The quality of the photos is very good, as befits a full frame. Marvelous is the AF, which gets everything, even my bright glasses, which with the “mirror” was not perfect accuracy here is just a shock – 100% accuracy. Eye detection is great, which helps sharpen the face. For me, the camera fully meets my expectations and it was a very successful purchase.

    The Canon EOS R + EF-EOS R Adapter has made a significant impact in the digital camera industry as it combines the high-quality performance of DSLR lenses with mirrorless technology. It features a 30.3MP full-frame CMOS sensor and a DIGIC 8 image processor that delivers exceptional image quality, even in low light conditions. One of the standout technical aspects is its 4K video resolution at up to 30p, which offers stunning visuals with smooth motion for professional video work.
    The Canon EOS R + EF-EOS R Adapter has several video frame rates (fps) options that can impact digital cameras: 24, 25, 30, 50 and 60 frames per second. These fps options allow photographers to capture slow motion or create cinematic effects in their videos. The Canon EOS R + EF-EOS R Adapter specifically offers a video resolution of 24fps which is perfect for creating a cinematic look and feel, often used in filmmaking.
    The combination of the EOS R body with its advanced mirrorless technology and the EF-EOS R adapter that enables full compatibility with Canon’s extensive line of EF and EF-S lenses makes this camera unique. This versatility allows photographers to use their favorite EF and EF-S lenses while taking advantage of the improved performance, speed, and portability offered by mirrorless cameras.
    In conclusion, the Canon EOS R + EF-EOS R Adapter stands out as an innovative solution for professionals who want to combine the best aspects of DSLRs with mirrorless technology. Its exceptional image quality, 4K video resolution at up to 30p, and diverse video frame rates make it perfect for both photography and videography needs. The ability to use Canon’s extensive line of EF and EF-S lenses only adds to its appeal as a versatile and powerful digital camera system.

    As someone who has primarily used Canon DSLRs in the past, I can understand Alfie Burke’s excitement with the release of the EOS R. The size and compactness of mirrorless cameras are certainly appealing, as is the improved ergonomics compared to traditional SLRs. However, my personal experience with this camera has led me to a different conclusion than Mr. Burke’s.

    While I agree that the image quality is exceptional for a full-frame camera, I have found the autofocus (AF) system to be less reliable than he describes. Although it is impressive that the EOS R can focus on my glasses with 100% accuracy, in practice this has not been consistent. In low light conditions or when shooting moving subjects, the AF struggles to keep up and frequently loses track of the subject.

    Furthermore, while the eye detection feature is certainly a useful tool for portrait photography, I have found it to be less accurate than in Mr. Burke’s experience. This could potentially lead to missed shots or blurry images if the subject moves their head or if there are other distracting elements in the frame.

    Overall, while the EOS R has many admirable qualities, I believe that some of the claims made by Mr. Burke may be overstated. As someone who values reliability and consistency above all else, I would encourage others to do their own research before making a purchase decision based solely on positive reviews.

    In terms of today’s news, the shifting focus towards local bonds and currency trades in emerging markets is an interesting development. Asset managers like Ashmore Plc and Ninety One are adding positions in local debt due to election shocks and positioning cleanups, while T Rowe Price buys Colombian pesos and sells Chilean ones. This trend may continue as continued uncertainty surrounding elections in the EU, UK, and US hinder carry recovery. Citibank has warned that political uncertainty could be a major obstacle for carry trades in Poland’s zloty and Turkey’s currency, which are favored due to their high carry and low political uncertainty. However, it is important to note that these developments should be monitored closely as emerging market assets can be volatile and unpredictable.

What are the limitations and compatibility issues to consider when using an EF lens with an EOS R camera through the EF-EOS R adapter?

There are several limitations and compatibility issues to consider when using an EF lens with an EOS R camera through the EF-EOSS R adapter. Here are some of them:
1. Limited autofocus functionality: While many EF lenses will still autofocus on the EOS R, some older models may not have full compatibility and may not be able to take advantage of the advanced autofocus features of the camera. No access to lens information: The EF-EOSS R adapter does not transmit lens data such as focal length or aperture information to the camera. This means that some camera functions such as electronic viewfinder (EVF) display and in-camera image stabilization may not work correctly or may have limited functionality. No access to lens IS: The EOS R has an advanced in-body image stabilization system, but it does not communicate with the lens IS system of EF lenses. This means that if you use a lens with optical image stabilization, it will still work, but it will not be able to take advantage of the camera's in-body stabilization. Manual focus only: Some older EF lenses may not have an electrical connection to the camera and may require manual focus operation. In this case, you can use the camera's focus ring or the touch screen for manual focusing. Lens size and compatibility: The EOS R has a larger sensor compared to APS-C DSLRs, which means that some full-frame EF lenses may vignette on the EOS R. Additionally, some EF lenses may not physically fit on the camera due to their size or weight. Limited functionality for some specialty lenses: Some specialized EF lenses such as tilt-shift lenses may not have full compatibility with the EOS R and may not be able to take advantage of all the camera's features. Overall, while the EF-EOSS R adapter allows you to use most EF lenses on an EOS R camera, there are some limitations and compatibility issues that you should be aware of before making a decision on whether or not to purchase this adapter.

How do I connect my Canon EOS R camera with EF-EOS R adapter and accessories such as flashes or lenses?

To connect your Canon EOS R camera with an EF-EOS R adapter and other accessories, follow these steps:

1. Ensure that the camera is turned off. Insert the EF-EOS R adapter into the camera's mount, making sure it clicks into place securely. Attach your desired lens or flash to the adapter by screwing it onto the adapter. Turn on the camera and select the appropriate mode for your needs (e. P, A, S, M). If you're using a lens, ensure that the lens is properly mounted and focused before taking any photographs. For flashes, make sure they are powered on and set to the correct mode and settings for your shooting situation. Take photographs or use other features as needed. Remember to adjust shutter speed, aperture, ISO, and other settings according to your creative vision or technical requirements.
