For years this forum made fun of ibis and mirrorless
It’s fun to see how the forum users now see a benefit to ibis and can finally see that mirrorless is the future
in just another year or so we will see folks adapt to the smaller bodies as well. the R5 is a break from the bulky slr bodies that folks swear is the only way forward
I still do not like mirrorless for photography and couldn't care less about IBIS for photography either. I am not a fan of the EVF especially the lag, mirrorless battery life, camera size, or pretty much anything mirrorless for photography. Also, no one has mentioned eye fatigue...staring at a tiny LCD screen so close to your eye for hours on end has to be more tiring than a more natural OVF. I love my 5DIV and will keep it until the mirror goes out.
With that being said, mirrorless is fantastic for video, I don't use the EVF, video is usually short clips anyway so battery life isn't as much a problem, and for longer events you can usually plug into a power source somewhere. Also, the small size is great for gimbal work; which is why I love reading about the R5's features but plan on getting the R6 and the C200. For the work I do, a lot of b roll is shot handheld (no time to setup and balance a gimbal) so IBIS is important to me as well.
The major shortcomings of my GH5 is AF, currently I have to shoot everything using manual focus, the color science out of the GH5 is terrible except in perfect lighting, and in low light it gets noisy fast even when using ETTR; so getting DPAF, 4K60FPS, dual card slots, Canon color science, and a 20MP sensor in a mirrorless body is a big deal to me.
