Medium* Format Digital cameras
Jan 22, 2017 19:27:35 #
No one mentioned the Mamiya 645. I use it. Not digital at the moment. They make digital equipment and are very good at it. The newest equipment will not accept the older lenses. But most of the previous equipment will work with the older manual focus lenses. It even has backs that are up to 100mg pix. Someday if I win the lottery I will be able to upgrade to a full autofocus Mamiya 645 digital . But for now I shoot, B&W on my 645 then scan the negatives. Not instant gratification but I have been using my equipment for over 30 years , so I now that 99% of the time I have a good shot. I am old school, I do not need to shoot 100 photos just to make sure I got the image. I know my equipment. I previsuallize my shot and when it is right...I shoot it. Same thing when I shoot 4x5.

Actually no. The disk of diffusion is cropped, not the lens. This error is similar to 'cropped' sensors.

Go for a Leaf (Mamiya is part of that) and get a true medium like the RB/Z system... Or whatever that thing is called now.
Oh, do you play?

AKA projected image circle.
My point was that the lens *does* the cropping --- not the sensor.

My perfect sensor size is four thirds. It keeps the equipment small. In my opinion, FF is only necessary for film.
Just obtained the Oly E-M1 MkII. Early playing around with it shows excellent quality results. Worth a look if something in the $2k range, plus lens, etc, is in your ballpark.

Lightspeed makes a sensor for 4x5 cameras. A bit pricey, but not really 4x5 inches. My personal preference would be an H6D-100, with three lenses. 50mm, 80mm, 150mm. My first purchase right after I win a lottery.

Why not just get a Phase1; they already have one with a 100mp sensor ? Their prices are even higher than the Hassy though

Medium format actually used to refer to many film sizes not just 120 6cm roll film. A popular format used to 127 film which is 4cm wide.

ah, wikipedia again. 127 format was never considered "medium" format. it was however considered "roll film".

err.... Think about it. The lens project a disk (I do not like circle at all*). The sensor is contained within that disk. How does the lens 'crops' anything?
The sensor just records whatever it is exposed to within its surface. Same as it does with a shift/tilt lens, is there a crop then???
The sensor uses its 'full frame' regardless of its size.
There is really no 'crop' but a magnification factor created by the lens. This 'crop thingy' is a misnomer, a red herring and nothing else.

Au contraire! 127 is 46mm film. One of its three negative formats is about 6x4.5cm, the smallest medium format available (Mamiya, Bronica, and others made 120/220 versions of the same format. Beattie Systems and Photo Control made long roll versions of it.) The lab I used to work for processed many miles of it each week for school photographers.

Semantics... a non-circular sensor always records only a portion of the image projected at it. When that projection magnifies the image significantly beyond the corners of the sensor, there's a crop of sorts going on.

Same as 120, with a thinner spool core...
Kodak made several versions of the same film for different cameras.

Correct! Kodak was a P.I.T.A. about that. I respooled lots of 120 to use in 620 Kodaks!

My first camera at age 4-1/2 was an Argus Seventy-Five that took 620. It sparked a life-long interest in photography.
My Dad left me an old folding camera from the 1930s. It took 6 or 8 frames on 616 roll film, each 2.5"x4.25". THAT's almost large format.
Same deal... 616 was just 116 on a thinner spool.

Yep! 116 came out in 1899 (Brownie 2a IIRC) then Kodak made a more "modern" spool for it in the 1930s making the 616. It was almost large format! along with it's brother 118 (post card size) 116 and 616 were made until the 1980s!😲 If I'm right Kodak actually made 620 until 1994ish. I never saw it that late though.
