Was thinking about some of the more esoteric panoramic formats and how common they are in use today. I would be particularly interested in how many cameras are being used in sizes other than 4x5, 5x7 , and 8x10.

My 8x20 gets fairly regular use these days, but I am not sure how many others are in Australia let alone anywhere else. I know there are a number of 8x20 shooters around but it would be interesting to know how popular the 8x20 size is compared to say the 7x17 and 5x12 formats.

I am interested specifically in panoramic formats larger than 4x10.

Any ideas/guesses/suggestions about how I can find out.

thanks
