Ricohflex, you don't seems to have sense of what each format is ideal for.
1) Medium Format are usually used for Landscapes, Architecture and Studio photography as they are generally too bulky to be carried around,
including the current corp of Mirrorless Medium Format.
2) Their lenses are up to about 100mm, (with the multiple factor, that is about 80mm only) for the common brands Pentax and Fujifilm.
They do not have lenses for 200mm or more, so it is probably not suitable for Birding, WIldlife, sports, events etc.
Medium Format Digital Cameras have been around for very very long. The digital backs have been around even before M43, but it has never impacted the sales of FF, APS and M43 in anyway. It is a different arena altogether.
M43, together with Ricoh, Pentax, Nikon with APS and FF, the sales have been declining the last 5 years. It has nothing to do with the format, but with a much newer alternative, the mobile phone. I lost count of how many friends with SLR are no longer using their SLRs anymore and solely rely on their mobile for their keepsake photos. When they have a special event eg. Wedding, parents 80th birthday etc, they just engaged professional photographers to do the job.
Hence, you can see that across the brands, Sony, Canon and even OM Systems, when you look at their latest offerings, it is targeted towards Professionals and Serious Hobbyist. Times have changed and mindset need to be changed too. Ricohflex, you need to stop focussing whether Olympus made the wrong choice on sensor format. It is no longer relevant. Right now is the target market and the application.
Photographers like myself, almost 60 years old, even if some company sponsor me with a Medium Format camera wih a few lenses, I would leave them at home or in my studio. I will never bring it out on any of my travel or trekking trip! So which system is left in the dust?
Recently the Internet got rumours of Sony medium format camera.
Is it possible?
And if true then what is the impact on OMDS MFT?
First commercially mass produced film camera was probably Kodak Brownie in 1888.
Over the next more than 100 years, film photography evolved and progressed. Various film formats lived and died.
Eventually Kodak filed for bankruptcy in 2012.
First commercially marketed (by Japan) digital camera was Fujix DS-100 in 1991.
Dycam Model 1 was the first commercially available digital camera to launch in the US in 1990.
Although Kodak digital prototype was in 1975 but obviously it was not commercially available to consumers.
1991 to 2022 is only 31 years. That is very short. Digital photography has progressed by leaps and bounds within this short period.
So the answer whether more camera companies will go into medium format in future is, in my opinion > yes.
Will there be buyers of these $10,000 to $20,000 cameras?
Yes. There are many people who buy cars costing more than $300,000. There will be a market.
Whether they need it, is not the point.
They have the money to buy it and some of them will.
Fuji already has mirrorless medium format digital cameras with interchangeable lenses.
No idea whether Nikon & Canon will follow.
There are others like Hasselblad, Pentax, Leica and Phase One.
When several manufacturers make mirrorless medium format digital cameras with interchangeable lenses.
Where does that leave the MFT sensor format, particularly OMDS?
It leaves MFT in the dust. As a part of history. An obsolete has-been, that was good once upon a time.
When medium format is commonplace, people will begin to perceive Full Frame sensor as the "small" format.
And the very much smaller sensor formats like MFT will be crushed.
MFT won't survive in that future market environment.
Just as it was in the film era when many manufacturers made medium format film cameras.
And there were even more 35mm film format cameras.
The previously made HALF FRAME (1961 Olympus Pen EE2) and 16mm (1959 Mamiya-16) film cameras became unpopular and companies stopped making them after some time.
