Oh, dear, nominal vs. actual formats. Oh, dear. wiltw, I've always understood that nominal 6x7 is actually 56x68, aspect ratio 1.21. Whose definition are you using?
cmon guys, any women will tell you size doesn't matter, its how you use it.
Don't forget Linhof's "Ideal Format", 56x72.wiltw, thanks for the reply. I agree with you that roll film gate sizes aren't perfectly standardized. As I said, I've always believed that 6x7 meant 56x68. I just looked at the GX680 manual, which says that it means 57x69. Just checked the Pentax 67 manual, 55x70. This Mamiya manual http://www.cameramanuals.org/mamiya_pdf/mamiya_rb67_pro-s.pdf says 56x68.4. You can't trust anyone.
Cheers,

Bill, thanks for the reminder.Don't forget Linhof's "Ideal Format", 56x72.
You should ask what the benefit compared with 6x9 is !What is the main advantage if any of a 6x8 negative over a 6x7 negative?
I am thinking about getting a 6x8 powerback for my RB67 and was wondering what benefit I will gain??
And that is the rule of 6x8 today because
there are no modern cameras to 6x9.
No recent SLRs or range finder cameras, certainly, but unless I'm misinformed there are still 2x3 view cameras in production. I suppose that for some prospective users they're not really cameras ...
Fuji did indeed run an interesting line up that complemented well:The ideal format is 6x9 with 120 film.
The rest is manufactured in the 20th and
30th.
But there are some - that is the advantage of 6x8 : 6x9 = NO options.
I decided to 6x7 because Pentax has a very great system.
But 6x7 is sometimes a problem.....
4,5 x 6 is also ideal from my point of view but it is to smal - at the end you are standing still with 135 films.
That is indeed a positive alternate..
To note 6x9 is half of 4x5 but the rationale of working with roll film is totally different, as well as the (lower) costs. The Fuji GW series were discontinued in mid 2000s and still plenty available. Infact, I chose one because it was modern (in the sense of being 20 year old or so). Strangely, it is one of the largest medium formats but due to lack of model cult it is rather cheap and available. One caveat of this camera is that its 35mm factor is rather manageable and swift to use, sometimes making 8 exposures too few. Sadly 220 is no more.Well, they're cameras, but of course they require a whole different way of working. It's hard for me to imagine a 6x9 view camera as a walking-around camera, where a Fuji 6x9 would be quite well suited.

6x9 is half of 4x5
Filing those 6x8 negatives is a real problem.Nine 6x8 negatives will fit in a single, standard size Printfile negative holder page.
Ten 6x7 negatives will not fit in a single, standard size Printfile negative holder page.
4,5 x 6 is also ideal from my point of view but it is to smal - at the end you are standing still with 135 films.

Filing those 6x8 negatives is a real problem.
My PrintFile 120-4B archival negative preservers will hold 12 6x6 negatives but only 8 6x8 negatives. This is dismaying because my Fiji GSW680 camera delivers 9 negatives on a 120 roll.
My PrintFile 120-4UB archival negative preservers are slightly bigger and will hold all 10 of the 6x7 negatives from my Mamiya RB67 camera but again only 8 6x8 negatives will fit. So where does the extra neg go? It goes into the next neg preserver page with annotations cross-referenced both ways to keep track of it; more work! And handling a single roll film negative rather than a strip of two or three is much more finnicky in the darkroom.
With 6x8, you get ten frames per roll. Ten is a nice, round number.
My tan/light brown Super Rollex ca. 1959 is marked "56x72". I'll measure it. The mask for the optical finder is also marked thus. I believe the literature which came with the camera speaks of 56x72, as though it is something new and remarkable.Bill, thanks for the reminder.
I don't know who to believe about this. Many web sites assert that Linhof's 6x7 roll holders' gates are 56x72. Emmanuel Bigler, who I salute in passing, shows a brown Super Rollex marked "56 x 72." But I can't find anything straight from Linhof about gate sizes and there are many Linfhof roll holders around marked "6x7 2 1/4 x 2 3/4". Its hard to believe that Linhof would change gate size during a model's production run.
FWIW my late (black) 6x9 Super Rollex is also marked 2 1/4 x 3 1/4. I measured its gate's length. 84 mm.
Cheers,
Dan
Pardon, I mixed up some digital format/aspect ratio where a 4:3 frame can be split in two 2:3 rectangles. Also, adding up some anectodical discussion on carrying 6x9 MF vs 4x5 saying the former is approaching half of the latter in neg size.Why do you believe this?
