Dear Simon,
sad to hear, well as long as 5x7 film is available, it's ok for ME, but...

Never really understood why 4x5 and 8x10 is so popular when 5x7 is so nice!
Many 5x7 cameras not much bigger than a 4x5, but all 8x10 very clumsy in comparison.
Don't expect you to solve this lack of my understanding!

Regards
Bertil
