Elonlukatski: For still life and landscapes these would be perfect. I have the 50mm and the 150mm V mount glass and they are gorgeous image producers.

Larger sensors cost a lot. They make sensors on a circular wafer of a standard size I think around 300mm wide. You're trying to fit square/rectangular sensors onto a circular wafer, the smaller the sensor the number you can fit goes up much higher (not only can you fit twice as many half-sized chips in the same area as a full sized one, but you can fill in the edges better with smaller sensors so you use the space of the wafer more efficiently with less wasted space). On top of that if a single piece of dust lands on the wafer during it's processing, the chip it is on is destroyed... if you can fit 100 smaller sensors on a wafer and 20 larger ones... one piece of dust cuts your production of smaller sensors by 1% while it cuts your production of larger sensors by 5%.

sibuzaru: it really shouldn't be that hard to make an adapter that could cock and fire the leaf shutter

It would probably have to be manually wound like the flexbodies. The shutter in those things took a bit of energy and would kill a battery rather quickly.

RGBCMYK: Now if they would just make the sensor 6x6cm the world would be happy again!

The mount won't work for a 6x6 sensor. It might work for a 53.4x40mm sensor, but it's not designed for 6x6. The current system is based off of the 645 H line (which was taken from Fuji's design) not the 6x6 V line.

PhozoKozmos: 56mm x 56mm (6x6) MF Sensor
79.2mm image circle

56/36=1.55555555 "wider factor" than FF 36x24
36/56=0.642857142

50mm MF lens
has a maximum horizontal (and vertical) fov aov: 58.50° "wideness view"
like a 32.1mm (32.14285714) FF lens

37.33mm f2.178 MF lens
has a maximum horizontal (and vertical) fov aov: 73.74° "wideness view"
like a 24mm f1.4 FF lens

Except the camera doesn't have a 6x6 nor a 36x24mm sensor. It's 44x33mm. Even if they make an upgraded version with the 100MP sensor, it would be 53.4x40mm.

Sorry I've had too many NAND flash devices fail and loose data on me to not worry about it.

Morvegil: Another camera for doctors and lawyers?

lakkot you can shoot a billboard with a 2MP camera... doesn't matter because the pixels could be the size of your head when you're looking at something from 50 feet away. I work with Hasselblads for art reproduction (though the multi-shot studio versions that have no moire and better resolution) and it's useful for that, but I have to admit if I go to a Hasselblad event, there are a lot of doctors and lawyers. Do I care? No because there aren't enough of us to keep Hasselblad (or Leica) afloat on our own, so if they sell some cameras like these to doctors and lawyers, they're still around to make the cameras I need for my job.

Shrinking a company is extremely difficult... and that’s basically what they did.

Kodak never made a single good user interface. Kodak picture kiosks, digital camera menus. They had amazing scientists but they never had designers. If they went to make an iPhone they would have made the Motorola Rokr. If they went to make instagram or snapchat it would look like it was a Windows 3.1 program.

The problem is hardware doesn't make money. Film and paper were products but they were different, they were consumables. The only thing Kodak may have been able to pull off would be to run an ISP or cell phone service. But even there those markets have huge competition.

Business schools like to give you the simple easy story, but one thing they don't tell you is many companies make it huge because of one thing, but when if that market changes and they've grown so big, it is very difficult to shrink a company gracefully. Sometimes there isn't a path to remain successful.

So you're far less short sighted and you even have the benefit of hindsight... so what was Kodak's path? Before you tell me "go all in on digital" ok... but how much money does Canon, Nikon, Sony, Fuji, Olympus, and Panasonic make on cameras each year? How does that compare to the adjusted for inflation income Kodak made on film? Even if Kodak had a monopoly on the digital camera market, they'd have gone bankrupt.

What do they mean by "tethered image support"? Both cameras already support tethered shooting with Phocus.

Karroly: So, a camera without a viewfinder to frame and check focus ?
I'll come back when they design one...

Hotshoe viewfinders exist but they pose challenges. For close subjects there's parallax issues, most e-mount lenses are zooms which is not ideal, finally there's no focus confirmation.

Now you can use a hot shoe viewfinder to give you a ball park aim, guesstimate framing of the zoom, and zone focus with a wider focal length and smaller aperture.

It's not clear if the camera has a light meter so you'll probably be using an external light meter or more likely relying on sunny-16. With those issues, it's not much better than a disposable camera and it is inferior to many point-and-shoot style 35mm compacts from the 90's. So that leaves a lot of us reading it saying "ok, this person put a lot of effort, but why am I reading this?"

I think it's a great learning project for the person building it and would make an amazing science fair project for a student. However the issue is for those of us reading the article, it's not exactly exciting or useful.

mosc: This should have a focal length reducer in it. There's enough room in there, correct? Could just expand the projection of the FF glass to cover the larger sensor. Doesn't somebody make one for Fuji's MF system?

You're thinking backwards... This is larger sensor from a smaller image circle. You need a focal length increaser (also called a teleconverter)

LJ - Eljot: Oh, sorry! I thought full frame means 6x6.

cdembrey, 4x5 (12.7x10.2cm) is the M4/3rd of large format. 5x7 (17.8x12.7cm) is the APS-C. If you want full frame you need to go at least to 8x10.

HowaboutRAW: The Leica M mount isn't believable, well not without mass vignetting.

NottsPhoto you know that the Hasselblad is a 44x33 format and that is larger than 36x24mm format right?

Tommygun45: I have a 2008 MacBook and a 2017 MacBook Pro 15 Loaded.

Yesterday I was trying to reinstall an OS on my 2008 MacBook because the hard drive had blown up and I had put in an SSD. You have no idea the process that was involved in trying to do this. I was on the phone with Senior level tech support guys at Apple and eventually they concluded there was nothing to do but bring it in to an Apple Store and hope for the best.

The problem was I could not download an ISO or dmg file from Apple. Accessing the App Store left me stuck in a "Your Mac does not support this OS" message with my new computer. I had to find a random Google Drive account that hosted Mavericks, download the ISO file, burn it to a thumb drive and boot from it. I figured this out on the phone while talking with Apple Tech Support. At the end of the conversation I told them that this was the final straw. How can it be impossible for an end user to reinstall an OS via USB through official Apple channels?

Greed.

Apple doesn't require a software key to install (having a copy is the key) but they allow you to buy a copy of old versions pretty cheaply: https://www.apple.com/shop/product/MC573Z/A/mac-os-x-106-snow-leopard
