Nikon FM2 Body
The very personification of a workhorse camera this has been dropped, dented, lost, found, rained on and trodden upon.
It was used daily as the body for flat-copying archival prints at Retna and is only still in my possession because Jessops refused to accept it as a trade-in due to the dint in the prism.
It hasn't been used for well over a decade.
It fell out of favour when I took the leap of faith with auto-focus and was a back up to my 801 (top plate kicked off with Speedlight by crowd surfer) and F90x's (stolen in a house break-in).
I then turned to digital.
It's very perseverence and dogged refusal to give in means that a resolution for 2012 will be to put a roll through it.
