    You overlooked Agfa's Karat and Rapid system. It took standard 35mm film in smaller cassettes, without protruding spool-hub. It gave the benifit of kind of drop-in loading.

    When Kodak surprized the photographic world with their Instamatic system Agfa had to react overnight so to say by re-stablishing their late Karat system as Rapid system and crank out masses of brand new designed Rapid-cameras to conquer those Instamatics cameras.

    Film graininess was still an issue back in the 1960s...so having to magnify the half frame image more, in order to make the same final print size, would magnify its grain size to be that much more visible.

    In the film heyday, enthusiasts commonly lusted for medium format because of the reduction in grain as seen in the final print. So the success of a smaller format would be inherently more disadvantaged with that desire. We are spoiled by finer grain film today, where ISO 400 is virtually the same in visible grain as ISO 100 film...that was not true back then, and it didn't happen until about 1990 or so!

    Back then there were 20 exposure rolls of film (and 36 exposure rolls), so 40 half frame exposures on a roll was not much different in toleration than a FF shooter using a 36 exposure roll. There were even 12 exposure rolls, so 24 half frame exposures was not much different than FF shooter with 20 exposure roll. So I don't buy the 'it took too long to shoot up a roll' argument as much of a factor to half frame demise.

    I don't recall processing cost for the film itself, but about half the emulsion area should have allowed half of the film processing cost; the per print price would be virtually identical, of course. Of course, processing costs are not simply about depletion of the chemistry, as the labor costs are just as high to process a 36 exp roll of film as it is to process a 12 exposure roll of film.

    12 exposure rolls came about much later, unless they were available much earlier. When I started in 1979 or so they were 20 or 36 (I wish E6 films still were - my slide pages hold 20, and I have some Elitechrome 24 exposure I bought online, which means wasting 16 of 20 spaces in a slide page.) 12 and 24 both came about much later. But there might have been 12 back in the 60s or earlier; I don't know about that.

    I have a Pen-D, and also a Superhedz Golden Half which, though being a plastic camera with plastic lens, one shutter speed and two aperture settings makes nice little snapshot images. Because of its leaf shutter, it works nicely with a small flash unit attached to its side-mounted hotshoe. It's also rather nicely built for a plastic toy camera.

    Due to its small size and light weight, I'm much more apt to take the Golden Half with me than the Oly Pen-D, despite the difference in lens quality, which I really don't see with 4x6 mini lab prints. And I'd rather break or lose a $40 plastic camera than a collector's camera like an Olympus half frame.

    The Karat/Rapid system I hinted at above had only a short strip of film. In case the appropriate camera exposed the 24x36mm format those films only gave 12 exposures (24 at 18x24).

    You should get a Minox and go to town. Quarter frame, or whatever they are...
    Quarter frame is massive compared to Minox

    Getting back to the OP. Too bad half-frame died, but quarter frame is alive and well

    With regards to the Agfa Rapid cassettes, they also fit the Ansco Memo, which was a half-frame camera from the 1920s.

    I had a very nice Pen FT. My favorite half-frame is the Agfa Optima_Parat. Excellent Solinar lens and accurate trap-needle exposure system.

    I've shot a lot with this camera and have been very impressed with it.

    Even so, I think the format has its limits when it comes to enlargements.

    Why did half frame die?

    Half frame, quarter frame.. It's all perspective... An 8x10 shooter would call a 6x7 a 1/8th frame and a 135 shooter a 1/25th frame shooter hehe (those were not mathematical just made up....protecting myself from the anal retentive "hey 35mm is only 1/20th man!" hehe

    Goid! Just didnt want to wait till I finished a roll to have it developed, When I startede doing my own, I bought my film in 100 ft rolls and loaded my cassets with 12 exp rolls
