My thinking about IBIS is that…
1. Yes, we can make photographs without it. Many of us did for decades.
2. We also made photographs without autofocus, auto exposure, high quality zoom lenses, screens to review settings and images, the ability to magnify the image for manual focus, custom settings, ultra-high ISO, the ability to store more than 12/24/36 images before swapping out our “memory,” Photoshop… you get the idea. ;-)
3. IBIS is plus with a minus, it is very useful in a number of real-world photography situations, and it has become more or less a standard feature on modern cameras.
I find it ironic that no one will acknowledge the prevalence of Leica M shooters in the world for decades, and the M remains a non-IBIS camera to this day. Yet, for Fuji to have a non-IBIS model is (allegedly) unthinkable in today's realm.
I can get a 50mm/0.95 for my Leica m. I do have 1.2 and 1.4 lenses for it. An f4 lens is allready pretty dark, and does require relatively slow shutter speeds in many situations. That’s when an ibis would really help. When you have an f1.2 lens, it’s much easier to shoot at shutter speeds that don’t require ibis.
But you are forgetting about the dof. A 1.2 lens might be great for gathering light…but sucks if you want to get a lot environment in focus. When I’m traveling, I want my images to show off the unique environment…not some fuzzed out background that could have been just as easily taken in my backyard.
Not poo pooing the f4 lens but the beauty of having a f1.2 lens is that you can close it down when you need to right?
35/1.2 (or 1.5-ish) on MF ... gonna be beasty. 0.95 (1.2-ish) would be monstrous. Also, the IQ of lenses that are that large aperture are either going to need to be stopped down for improved IQ performance ... or, be designed as behemoth glass to achieve that speed and be well corrected. Now, you have to carry that size / weight and still stop down to achieve reasonable DOF.
At which point, you are talking about an ILC ... which already exists. The point here is to provide an alternative to that packaged in a way that yields a different shooting experience than toting an MF ILC and ILC glass.
