The switch from Ektar to Tessar lenses was due to cost, at the time - the Kodak lenses were more expensive. Both were good.
The history of Hasselblad's digital systems are tied to their multiple owners' boards and finances.
In the early 80s, Hasselblad foresaw digital, formed a team, and developed the DigiScan, which allowed newspaper to digitally scan film and transmit the image to their newspapers for publication on the same day.
In the early 90's, they stopped development on their film cameras, and worked on a digital version, which came up with a tethered tripod mounted device that looked more like a projector, it took digital images using Philip's FF 6MB sensor (which they had exclusive use). They were owned by Incentive, and were well capitalized so they could develop digital.
The short story is that a private equity firm bought it in late '95, and now they were in debt because Incentive had withdrawn the capitalization prior to sale. The new board did not want to develop the new device, and wanted something more like a digital back that 3rd party companies had. So the digital team came up with a digital back using the same sensor, which they demonstrated on the board by taking their picture and displaying it on a computer, but the board had already decided that it would be cheaper to dismiss the digital team and contract out. But '96, all but 3 people on the digital team had left.
In 1998, they signed up with Fujifilm to develop the H series on a 50/50 basis.
The details of this was published in an article by Sandstrom in the IEEE Annals of the History of Computing. I remember seeing a picture of their original digital camera, which was nicknamed Big Bertha because it resembled a giant version of that golf club head (on a tripod). I can see why the new board members that don't have the vision and technical knowledge of the industry, see a product they don't like, as it was quite a departure from Victor's compact portable device. And the Board's objectives (published at that time) was to own the company for 5~7 years and make a profit.
