I wish I could give this camera more than 5 stars--it's been fantastic. I am a birdwatcher and have always enjoyed photographing nature, so a few years ago I started out with a Canon SX70. I've used that for several years (and am still using it) but recently wanted something that would capture more detail such as feather structures, etc. I have also become interested in spiders and macro photography. So while I'm not a professional photographer, I wanted a better camera as I was pushing the SX70 as far as it would go, especially in low light conditions where I found it had chromatic abberations at times. Enter the Canon EOS R5. I've only had the camera for a month and am still working with it to find the best settings for what I do, but the quality of the photos is amazing (especially considering that I'm not a great photographer and have no real idea what I'm doing). It is so worth the money. I've move the focus to the back buttons (I highly recommend this and watching the youtube videos by Brent Hall for the most important settings for wildlife photography) because I've found that while I set the focus to use animal eye detection, I use spot focus more than animal eye because I'm often photographing small birds in challenging situations such as swamp/forest or marshlands. In those situations, the animal eye focus often focuses on the twigs or reeds instead of on the bird. So I set up the * button for animal eye focus and left the AF ON button for spot focus while the shutter button simply meters and takes a photo. Oddly enough, what I find is that I use the animal eye focus to find the bird amidst the reeds or twigs and then use the spot focus to actually focus on the bird while I take the photo. It sounds weird, but it works for me and wouldn't work if I had left the focus on the shutter button. The point is that I have three custom modes and set up C1 with the settings that work for me, as well as setting up the back button focus, which means I can get some amazing shots. Just the other day, I was in the marsh and caught a brief glimpse of a common yellowthroat. I used the back button spot focus and thought for sure that I would only have a blurred photo of the bird before it flitted away, but when I looked, the bird was perfectly in focus. The camera and especially the lenses are much, much heavier than my old SX70 and it can be a little unweildy, but it has given me the extra resolution and detail that I sorely needed. I am also happy to have less/no chromatic aberrations. So far, I've been using solely Canon lenses and they've all worked very well. I am extremely pleased to have a camera now that I can "grow in to." I've also been interested in astrophography and the R5 is also capable of that, so I have additional uses for it as well as nature photography. It is an extremely versatile and well-built camera. It's solid and is definitely the way to go when taking a step up from other less powerful cameras.
