So I'm wondering...for the D300 it shows a shutter life of about 150,000 and the D3 about 300,000. My question is, when your shutter 'dies' how do you get this repaired? I'm assuming a new shutter can be placed in the camera, but is this feasable, meaning would it make the camera new again (or as new as it'll be given the circumstances) Also, does anyone have an estimated price to get a shutter replaced? Will the new shutter affect anything such as image quality or can you simple replace the shutter and shoot for another 150,000 or whatever the case is for the particular camera? Thanks in advance!
