David, this is a good start, and if each add something then we can have that thread which can be a good reference, sure it will not stop posting threads for new members, but it will help a lot in answers and even those new members may not start threads asking many questions after looking at that reference thread.

I suggest we start with one size format, then when we include most important things not necessary 100% details then we can move to another size format, let's start with 6x4.5 then 6x6 then 6x7,...etc.

In film field of MF i have only 6x6/6x7 and 6x9, i can contribute with what i have, but i am not an equipment expert, i sometimes come here to ask or find information about something i have or want to get.

How about first start by categorize the type of cameras in MF world, then we can put each type on different format sizes.
