I've gotten excellent, satisfying photographs with a bevy of FourThirds, Micro-FourThirds, APS-C, and FF format digital cameras. Literally thousands of them. I've sold them, licensed them, made a living from them, won exhibitions with them, etc etc. I continue to use my APS-C Leica CL and make tons of great photographs with it.
So why did I spend the money to acquire the latest Hasselblad 907x/CFVII 50c back? The answer is simple: Because I was looking for something specific in the qualities of photographs made with ultra-wide lenses that requires a larger capture format.
It is this specific 'something' that makes photographs from a Hasselblad SWC or other medium format film camera very different from the same photographs made with a 35mm film camera and a lens that provides the same angle of view. The something is the specific coupling of focus zone (depth of field, if you would) and field of view that is dependent upon precisely the size of the format and its relationship to the focal length of the lens and the size of the taking aperture.
There are other benefits to the medium format digital cameras as well, of course. And they're all worthwhile benefits, although many of them are slowly being approached by the best FF format sensors. But the DoF-FoV relationship cannot be approached by anything but specific capture format vs focal length attributes —*you'll never get the same relationship with a FF, or APS-C, or FourThirds format camera. (In truth, you won't get the same relationship with any two of the four, but those three are all much more similar than jumping up one more notch to 33x44 and beyond.)
If
this specific quality of a medium format digital camera is not significant to your photography, then sticking with FF makes good sense given the price, quality, and availability of top-line FF systems today.
It has taken me many years to feel that what I wanted was worth the price and for the prices to come down to where I could stretch to afford them. I'm not endowed with enough excess wealth to consider hopping about different MFD systems for the joy of "finding just the right one." So I made my choice on the basis of "what do I have now that I can move forward into the MFD world" along with "emotionally, what do I like?" I've made my decision to go with this Hasselblad system because it integrates so well with my existing Hasselblad V system AND because I like the concept it expresses much more than the competition. It's not perfect by any means... But it's good enough for my purposes because it gives me what I wanted when I considered buying it.
You have to make your own decisions on these things, after doing the business of making photographs, seeing what worked or didn't work, studying the reasons as to why that might be, and considering what might do the job you want. There are no magic bullets; there are no perfect systems. There are only tools and your creativity, photographic vision, and skills to use them.
