A misunderstanding needs debunking:
the apertures needed to get a given DOF lead to the same diffraction effects with the same image detail ("pixel count") in any format; just at a proportionately...

MrQuimper, I hear there are many ways that people can instantly share photos from their phones with friends.

SD Express changes to the same PCIe (one lane) and NVM, so it is roughly comparable to CFExpress type A and about half the speed of Type B. I don’t know it compares for robustness and such, which...

Phase One already has a product line for drone photography:

The XC offers none of the remote operation controls and only one lens choice, so is not...

To be fair, it does not weigh much more than either a Fujifilm GFX 100s or Hasselblad X2D 100C with their widest lens option

The lens on it own is about US$12,000, so a bit under $5000 extra for the "integrated body". Could it make sense to offer several bodies based on several XT lenses? Compared to an Alpa body (or XT...

This costs about $5,000 more than an XT view camera body with the same back and 23mm Rodenstock lens. Quite a premium for a modest weight reduction, whole losing the other lens options and controls...

I think my comments about HEIC/HEIF have been misunderstood. There is no sign that it is replacing JPEG anytime soon, if ever; what I meant by "universal" is that there is hardware support for it ...

There is now at least one good, fairly universal alternative to JPEG for "instantly viewable camera output": HEIC, part of the " High Efficiency Video Compression " (H.265) video standard, which ...

Thanks Jim, I thing the difference is that I am talking about the detail to be seen in the "raw" image whereas you are allowing for post-processing with deconvolution sharpening — where it seems ...

I’m not clear about the aliasing issue (do you have a link on that) but diffraction at a given f-stop is also a limit on resolution: at f/11 in 44x33 format, the Airy disks are about three times ...

I agree that Pentax was eventually held back by seeking compatibility with 645 format SLR technology—both the lenses and the body with a 645-sized reflex viewfinder system; Fujifilm and Hasselblad ...

I agree with TechTalk that Hasselblad is probably following the best route for a  “general purpose, carriable” system in what I suspect is the largest viable digital format for that, 44x33: the ...

Thanks Jim for that wonderful blog post; I have added it to my reading list. My simplest take-homes: - when shooting “equivalently” (same FOV, DOF and exposure duration), a larger format can ...

Rich, no question that these 44x33 format live view cameras can give very good results hand-held, and that once you have one, occasionally pushing the ISO speed up makes more sense than carrying a ...

Yes: if, as you suggest, diffraction sets an upper limit of about f/11 before the detail recorded drops significantly below "100MP worth", then (as I argue above), the DOF and strength of OOF ...

I'v seen just a few with digital kit like a Hasselblad H body with digital back—but no disagreement that there is very little evidence that "hand-holdable and 100MP+" is a market large enough to ...

Your f/11 and my f/2 agree; they are measuring different things. Firstly, the DOF (when viewing "normally" in each case, as with same sized prints viewed from the same distance) varied with format: ...

I am inclined to agree: though I have seen a few examples of medium format DSLR's used hand-held, it always struck me as ostentation, not a realistic need for such high resolution. But no, I only ...

In a sense, my question was about whether there will be sufficient use cases for a "hand-holdable, general purpose" EVF camera system with the 54x40mm sensor to be commercially viable; quite ...
