This question is sort of touched on in other threads but i though rather than hijacking one of them.... As the shutter count seems to be a measure against how long the shutter mechanism may or may not last, If i was to replace a faulty shutter mechanism on a Nikon D90 with the prospects of selling it. Should i reset the shutter count on the D90 so that it shows the actuation count of the new shutter? My view is, if I bought a camera with a new shutter mechanism I would want the actuation count to reflect the current shutter's actuations. but it would also be nice to know how much usage the camera previosly had. Thoughts.
