I am looking for 1 or 2 Hasselblad A12 backs for my 500CM. And while we're at it, what is the difference between a 'matching' back and a non matching back? Also, why do they range from about $100 to $400?
The backs have numbers on the insert and shell, the last 3 numbers should be the same on each. In practice it often doesn't matter, but you want to know its been tested, so there is some uncertainty that keeps the price down. It can be a good user option though.
I have "matching" and "non matching" backs and would challenge anyone to point out any difference in negative quality-I've never seen any.The older 12 backs have an asa dial at the back that covers a hole which enables you to look at the paper backing on the film-newer ones dont have this.I recommend a look on youtube to familiarize yourself with backs before you buy.

I think the concept of the backs and the inserts matching means they were machined together and QC was such that it was precisely fitted and matched in all gearing and fittings. In most cases it would not matter I'd imagine and I too shoot one or two backs that do not match. I guess with wear and use over time there is a theory that matching ones would take longer before "failing" or wear better as unmatched ones might not be as smooth or the gearing as precisely fit which could grind together though even minutely so. All things being equal if you can get matching numbers do so of course. How much more money for that and whether it's worth it is up to you.
Good place for hassy backs, though I'm not sure their international policies. Great reputation overall especially for conservative grading, I'd not hesitate on anything BARGAIN grade and I've even got very nice UG stuff from them. Good return policy and warranty on used gear too:
