My back-up DSLR, a Nikon D70 died yesterday. It started displaying "Err"\nand refusing to get up, regardless of what I tried (different battery,\nlens, card, firmware upgrade and even full factory reset). Local camera\nshop service chap spotted that one shutter curtain is jammed - the metal\nblades are visible while they should be hidden. Repair will cost more\nthan it's worth.\n\nA websearch threw this up:\n[URL]http://www.olegkikin.com/shutterlife/nikon_d70.htm[/URL]\n"Average number of actuations after which shutter died: 52,925"\n\nIt had never occured to me before that DSLR shutters have a finite life\nexpectancy.\nWorryingly, my D80 comes out even worse at 42,860.\n\nThe good news is that I've had the go ahead to buy a D700. The above\nsite only reports one death, at 380,000, with the average still alive\nafter 104,000.\n\nNo idea if the sample sizes are sufficient for these to be truly\nrepresentative, but it still makes interesting reading.
