I've always purchased used gear through KEH, but never a digital camera. They tell me they assess condition on a D810 body by cosmetics, not shutter count. Also, that shutter count can be inaccurate anyway. So hypothetically sounds like you could purchase a 'LN-' camera with 100,000 clicks on it. This makes me hesitate and consider just buying new. Or maybe it would make sense to buy from them Ex+ or Ex condition. What is the expected shutter life expectancy shutter count on these cameras anyway? Thanks for any comments.
