So if I am shooting a dusk cityscape at 1/30th of a second or less, ibis is not helping?This is not meant as an insult, but you don't seem to be aware when IBIS is helpful either. Typically you would set shutters speeds of at least 1/125s for breathing subjects to achieve critical focus. Sometimes, if you have very static subjects (e.g. old people), slower is possible, but for critical sharpness it is always better to go a bit faster. IBIS has next to no effect for the shutter speeds mentioned (1/125s and above for lenses < 135mm). In this case your exposure settings are the main driver for sharp pictures. If you have longer lenses, IBIS isn't all that helpful either, as IBIS can contribute only very little to focal length > 135mm (the effect will decrease the longer your focal length is).Many people that value IBIS, as do I, shoot in all those scenarios that you describe. It also allows people to buy optically nice but slow lenses, which are far more affordable than $1000 1.8 primes or 2.8 zooms. Part of the reason my 24/70f4 zoom is valuable is because I don't have to buy a $2000 more expensive lens to get that extra stop of light that IBIS provides.Why do you think it is that important? You are a bit contradicting. IBIS is most helpful for video and only a handful of stills shooting scenarios. If you photograph any breathing subject you will probably not rely on IBIS (due to necessary shutter speeds) and for tele / birding etc you have to rely on optic stabilization anyway.Again though the main thing to me with the R8 is the lack of image stabilization. To me that's downright appalling just on the principle of it. To me there are certain features you just don't leave out no matter what, like PSAM mode, hot shoe, RAW mode, etc. To me image stabilization is one of those. The camera could have 65 mp full frame, shoot 70 fps, be as small as a m4/3 body, have the most amazing ergonomics, snd cost $1000--but if it lacks image stabilization, it's a fail. (I realize my Z50 doesn't have it, but I still feel this way, because even the entry level Z5 has it.) Other people may feel otherwise, I don't care, that's my opinion.
What is left is some handhold cityscapes in low light or some special occasions where you actually need super slow shutter speeds and can't use a tripod / artifical light. In my world those occasions are rare. As I already said, most people don't even know if they benefit from IBIS or not, you seem to be one of them. IBIS is not a necessary stills feature. I used an EOS R with the RF 28-70 for people photography without any issues for years. To me there is absolutely zero difference between using the R8 or the R5 with lenses w/o OIS. All depends on the actual use case.
The argument that IBIS helps with slow lenses is invalid, as the minimum shutter speed is a precondition for critical sharpness, either for fast lenses or slow lenses. Even if you have the NOCT and magic manual focus fingers, you will ne be able to get sharp pictures of your average 5 year old toddler at shutter speeds significantly slower than 1/125s.
