I'm actually shocked to see this in 2013. I know we put up with the partial metal mount for too long (really should be fully metal) but this is a real step backwards.
Might have passed years ago with super budget 35mm bodies having a plastic mount, but 2013 no way...
Even Canon's EOS 1100d has a full metal mount. Sony are really penny pinching here

and apparently, your Maxxum 5D had it also (but apparently it didn't bothered you)
