Bought this as a hoped for upgrade to my previous Canons (20D, 7D, 5Diii-- now 12 year old tec). Had a variety of Ef lenses so bought the adapter rather than springing for the RF (and quite expensive) ones. I also have an old 2x offbrand teleconverter I rarely used because the autofocus never worked with my previous camera bodies. Also own a 400EX flash gun, Kenko extension tubes and a Yongnuo setup to handle off camera flash. Much to my surprise and delight, they all work. The teleconverter now provides autofocus for my 70-200 f/4 L (non IS but in body IS takes over nicely) lens, though not the Sigma 140-500. The handgrip doesn't fit (smaller body than the 5D) and my remote shutter releases don't fit the socket (why Lord why change the connection?). However, the Yongnuo can be attached to the camera to act as a remote release and it works. The manual says that the rc-6 is compatible but other sources, including Canon's own, doesn't list it as a compatible camera. Hmmmm. No cable to connect the camera to my computer is provided. Why is that left out? In theory, I could connect using bluetooth. I prefer to use my card reader instead. I have only had the camera for about 10 days and haven't had a chance to test it in all or even my preferred conditions. So far, image quality is very good, with high ISO images cleaning up quite nicely in Lightroom. My landscapes seem to need a bit more work than my 5D ones did, but that could be due to my changing notions about appearance and the lighting conditions I have had. I have never been one to test the various autofocus options available on my previous cameras. The controls on the r6 are much easier to find and work very well. My backyard songbirds seem to have a higher hit rate using the eye detect animal, servo, high ISO and shutter priority set (1/500 second). This combination, esp with a tripod mount, might not be that different from what I would have gotten with my previous setup but I am satisfied, even it I am simply experiencing a placebo effect. Controls seem well organized, but it has taken me some effort to find them and learn to use them. After taking on that learning curve, I am pleased; they seem actually simpler. Sample images are all worked over in Lightroom, not straight out of the camera; I'm an intermediate skilled photographer and Lightroom user. Your mileage may differ.

I love this camera. I do event photography and lifestyle and it's amazing. the quality and use of the camera are very easy to learn. ONLY issue I have experienced was it overheated on ( 4k 24fps ) after using for 45 mins straight ( recording pastor in church ) but then i put it into ( 1080P 24fps ) and i could shoot all day long. if you shoot 4k 24fps in small clips here and there ( b roll ) it works great This is my hybrid camera so as I shoot video, I switch over to pictures, get a couple of shots, and back to taking video. Handels any job so far that I've had it. I love it it's perfect for what I do. I have it paired with a canon 28-70 F2 its heavy but a beast !! amazing set up !

Now that I’ve had this camera body for a few months, I can confidently say that it has transformed my work. I shot portraits on a canon rebel XSi for something like 5 years, so obviously any upgrade in iso performance and autofocus quality in particular is substantial in my case. That being said, the autofocus is absolutely fantastic. Once you learn your way around the numerous modes and scenario options, soft focus will be a problem of the past. I’ve found that I feel comfortable using ISO as high as 3200 without noticing much noise, and higher ISO settings have minimal effect on the dynamic range. On that note, the color rendering and dynamic range are absolutely fantastic. It is disappointing that canon would lower the mp count to 20 for this camera to lower the cost, but it has not been an issue for me as long as I’m intentional about my framing while shooting so I don’t have to crop much. For those of us who can’t afford the r5, I think this is an all-round great body.

I've had a long line of Canon cameras starting with a T2i and including several APS-C and FF EF-mount cameras. With exception of a brief relationship with the original Eos-M, this is my first mirrorless camera, and this camera is SO MUCH FUN TO USE. The controls are perfect, so good in fact that I've made the jump to shooting in Manual mode after being a dedicated Av mode shooter with my previous cameras. The autofocus is fantastic and quite magical to see the eye-detect follow birds around. Dynamic range and high-ISO performance are leaps above the 7Dii that I replaced. My EF lenses are working great with the EF-EosR adapter (sold separately). I haven't tried video yet.

I specifically bought this camera for taking indoor sports pictures. I used it with a rental Canon RF 70-200mm f2.8l lens and my pictures came out awesome! I've yet to try it with Canon RF 70-200mm f4l lens to see if that lens may suffice since it's cheaper and available to buy in the market right now. Battery lasted the whole day. Overall I'm very happy with this camera. Very easy to use and RF lenses are significantly a lot lighter than EF lenses. It's great taking pictures even in low light. I'm very happy with this purchase.
