Why no square digital backs any more

Why didn't Hasselblad at least stay with the square format in digital backs? My PhaseOneP20 is square (well 4086x4088, near enough) and I love it, I wondered why all the manufacturers chose to go to rectangular as digi backs evolved and advanced.

Is it simply the cost of producing the sensors?

I suspect that it's more cost effective to produce 4:3 ratio sensors and then you can crop. Certainly my Leaf allows me to select the desired output format and will crop in camera. That way you at least have choices.

Personally I love the square format. It's one of the things I really liked about my old Kodak DCS645M back.

I'm not sure about the IQ140 or IQ160, but the IQ180 is to offer 1:1 square ratio at 60 megapixels. I enjoyed the square format of the Kodak 645M too---so I look forward to seeing how the IQ180 incorporates the square format.

A square 48x48mm sensor costs a lot more to make than a 36x48mm sensor, but 99% of users would crop to a rectangle or buy a cheaper 36x48mm sensor in the first place. Not only is the unit cost of production more expensive, but given that the market for the square version is so small, the chip maker would have to charge a high price per sensor to recoup R&D and setup costs. What makes it even worse: the back maker would have to do the same. At the end of the day, the back would be so expensive that there is no potential customer base left. It's just not a viable proposition. Square shooters will have to keep cropping rectangular images for the foreseeable future.

The square format is far less popular then the rectangle. The Mamiya 6 lost out to the Mamiya 7 for that same reason. It simply is not cost effective to produce one.

I'm looking forward to seeing how the 1:1 is implemented on the IQ180. I do enjoy using this format on some of my micro4/3 bodies.

i have always loved the sq, has the benefit of never needing rotation!
since one can always crop rect to sq after the fact the issue in this context is how you view the scene. For example, with a tech camera, your main view might not be until the preview image, and could that be selectable to be sq? But that is not really the same as a sq viewfinder and pre-viewing while composing, all in sq

I miss square and sometimes still previsualize as square, but in reality I rarely crop to square. That had been my intention when I went to the Hasselblad H system.
