camera arrived in perfect condition and is taking very detailed images and excellent video. I am using this R camera with the canon RF-EF adapter and my EF 16-35mm F2.8 III L lens. I looked on youtube for help with the setup as this camera has so many menus to customize it.
It'll Compose, Calculate and take the shot quicker than a flash!
The elephant in the room is the cost and video issues. I don't do video so I don't care about that aspect and Canon has fixed some of the issues with the latest firmware releases. As for the cost, there is no getting around it. For those able/willing to accept it, you will be getting a great camera. I was an old DSLR snob for the longest time but I haven't touched my DSLRs since I got this. I primarily shoot wildlife (birds) and landscape images. The shots I get with the R5 are incredible. I opted for the R5 over the R6 knowing that I would occasionally need to crop in for some bird images. I am able to maintain quality when cropping.
