I don't really understand ... the format of a panorama as well as the lens is chosen to suit the subject. There are almost as many panoramic formats as panoramas. What insight is a "comparison of the various panoramic formats" supposed to bring?

Dear Olaf, thank you for your thoughtful comment.

I try to decide between 6x12 or 6x17. And I would like to see the difference if a scene is shot with a 35mm or 55mm lens on a 612 in comparison to the same scene shot with a 72XL  or 105mm lens on a 617.

I will be able to carry only one lens or two. So I have to get everything done with a certain combination of lenses or even with just the right choice of one lens....




So, can anybody help?

Here is a list of analogue cameras currently in production:

Or have a look at the section Equiment on the page:

Go with the 612 format. The linhof has a pressure plate that adjusts for 120/220 film. The horseman does not.

I had a horseman 612 with a 55mm grandagon lens which I recently sold, it was an awesome camera, very light and small with excellent optics, but the lack of 120/220 switching was the only shortcoming.
some examples are here. http://www.stoqq.com/lightboxes/panoramics

Ah. So you are contemplating the purchase of a dedicated medium-format panorama camera with a fixed wide-angle lens (as opposed to a rotating lens or to stitching frames taken with a regular camera).

Well ... the most obvious difference between 6 × 12 and 6 × 17 is the frame's aspect ratio: 2:1 in the former and 3:1 in the latter. With 55 mm lens on 6 × 12, you'll get the same horizontal field of view as with an 18 mm lens on a 35-mm camera, or a 12 mm lens a APS-C camera. If you have one of those, simply crop the 35-mm or APS-C frame vertically to a 2:1 aspect ratio, and you'll see what to expect from a 55 mm lens on a 6 × 12 camera (without the superior resolution/image quality, of course).

With a 72 mm lens on a 6 × 17, you'll get the same (with a grain of salt) horizontal field of view as with 55 mm on 6 × 12 but less vertical field of view, according to the more extreme aspect ratio.

A 35 mm lens on 6 × 12 will yield the same horizontal field of view as a 12 mm lens on 35-mm format or an 8 mm lens on APS-C format (8 mm super-wide for APS-C doesn't exist; the shortest available currently is 10 mm---shorter lenses than that are fish-eye, not super-wide-angle).

A 105 mm lens on 6 × 17 will yield the same horizontal field of view as a 22.5 mm lens on 35-mm format or a 14 mm lens on APS-C format.

So to get a picture (pun intended) of what to expect from the medium-format 6 × 12 cm and 6 × 17 cm panorama cameras, get a 35-mm or APS-C format SLR or D-SLR camera and a super-wide-angle lens, shoot a few frames, and crop them vertically to 2:1 and 3:1.

Most  panoramic photographers  want a 3-1 one ratio (617), not 2-1 (612). Of course you can always  crop, but in my experience, being restricted to the format you want helps with composition.  I think the 72mm lens for the 617 is too wide. I've used the 90 with some success, but even longer also makes interesting composition.  I like the 90mm on my Xpan but wish they had made something a bit longer. I  also have the 30mm  but rarely use that.
