65:24 X-PAN

The XPan format, images in the '65:24' aspect ratio is the format captured by the Hasselblad XPan, a dual-format auto-exposure 35mm film camera capable of capturing images both in the standard 23x36mm image, as well as in full panorama 24x65mm images. The camera was introduced in 1998, in collaboration with Fuji, which also introduced their own version of the camera, the Fujifilm XT-1.

Interestingly, the 65mm width of the image format is similar to that of a medium format image width, giving the notion that the XPan is also a medium format camera. The XPan was made available with three primes, 30mm, 45mm, and 90mm manual focus lenses.
