The reason why Canon doesn't make a film SLR that includes the features that bring their cameras ahead of Nikon is because they don't think enough people will want to pay for them. And that's probably right.
Anyway (D)SLR use phase detect autofocus in which you don’t have to figure out much at all.
Mirrorless is another thing.
Last time I looked the digital back for a Hasselblad was ~$30k.
Put another way, if over night Canon had won 100% market share of all film cameras it would not be noticeable in the next quarterly earnings report.
Heck, I'd say "in the grand scheme of things", if you look at some of the data available (https://petapixel.com/2017/03/03/latest-camera-sales-chart-r...), stand-alone digital cameras "don't matter market-wise" compared to what has replaced them for a lot of people -- smartphones. Not that all stand alone digital cameras will disappear anytime soon (especially in segments like the DSLR market where the lenses can offer advantages for certain pictures), but the general purpose "compact digital camera" is probably doomed.
I paid more for the 'blad than either of my 4x5's.
(Not to mention the cost of 4x5 or (shudder!) 8x10 processing; B&W is eminently doable in the home, but IMHO where LF really, really shines is with dias film - developing that at home is not for the faint of heart.)
A digital back can improve workflow, but quality is still better with film at those sizes. These are studio cameras through and through; and I was able to connect a Hasselblad to some el cheapo Chinese lighting setup I bought on Amazon a year ago. That’s backwards compatibility.
At the end of the day Hasselblad is only 6x6 (i.e the negative size), but there are many bigger format (in medium format) cameras available like Mamiya 6, Mamiya 7, GW690III (which is 6x9, twice the negative size of Hasselblad H1's 6x4.5).
If you are looking for the ultimate medium format system camera, the obvious answer is Fuji GX680. It's waay bigger than the Hassy, and you can also put digital backs on it. The only downside is it's electronic camera, not mechanical.
No autofocus, no auto-exposure, and costs almost $4700 body only. Not something the typical film shooters will use, though :p
I think that because they were the dominant brands in 35mm in the film era, they still have fans today among people who still like to shoot film.
