the M645 does not have interchangeable backs.

With the price of M645's at the moment, they sort of are an interchangeable back

I confess I'm thinking of getting a second body (a 1000s this time) as a "back up". Because you always need just one more.

I got another 120 insert and it fixed my problem!
