Title: New names for digital medium formats?
Post by: marc aurel on September 23, 2016, 10:35:03 am
There are some discussions like "is 44x33mm really medium format?". Some started calling it "miniMF".
Somewhere else I read the term 433-format. For 50x44mm you could use 544-format. It would make talking about it a bit easier.
Of course there are things that don't really fit in. Like Leicas 45x30mm sensor. But generally I like this approach.

What do you think?

I'd call it the APS-H of 645  ;)

Well, there have always been various flavors/sizes of medium format sensors.  Not sure there's much of a problem referencing them.

As for those who would claim the smaller MF sensors "aren't really medium format"... I have to smile.  A long-in-the-tooth film shooter might shake his head and tell you there's never really been any kind of real medium format digital.  They're all cropped, after all.
Title: 36x24, 44x33, 45x30, 54x40 ?

I'd like to think that anyone who cares enough about photographic equipment to use a digital camera in a format "35mm" or bigger, and to debate focal length equivalents and DR and resolution and high ISO speed performance and DXO scores, could easily handle actual sensor dimensions in mm – so-called digital medium format now has two main formats: 44x33 and 54x40.

But apparently, the mob tendency is to shoe-horn new formats into old names, including using an obscure, failed and obsolete film format (APS-C) to inaccurately describe the dominat DSLR formats, while bizarrely, the best-known still photography format name, "35mm" has been abandoned!

Hi,

Fuji calls it the G-format?

With digital, we can have any format that the sensor makers decide to make. With film it was different, there were a few widths of film.

But, we still live by old conventions, based on conceptions of the old millineum.

Best regards
Erik

The usual convention vas to call the various formats: x1.0, x1.1 and x1.3. 44x33mm is "x1.3".

There are some discussions [on Petapixel] like "is 44x33mm really medium format?".
