Let me be as kind and pleasant as possible as this was my original intention.
Dear Friends:
1. Please when writing a response use less transitions and check your grammar and spelling.
2. Don't contradict yourself by telling us to first go and buy a cleaning kit and fix the problem and then second tell us that if we wish to return the product for a refund or exchange, then go ahead. It is not our place to fix or remedy the problem of a fast-tracked product by a multi billion dollar company (Nikon).
3. Being a 'professional' has nothing to do with knowing how to clean a sensor. I'm not a professional sensor cleaner, I'm a professional photographer. Being a professional has everything to do with holding Nikon accountable for what they've done here. There are people that have risked a lot by going with this product only to have to then spend time, money, and energy trying to solve the problem, fast, while clients are waiting in the wings. I would think that a 'professional' should be able to rely on Nikon and go out and purchase a D600 or two for a new shoot and not have any foreseeable problems. Then only to find out that in post production nearly all of their shots need drastic touch up. These 'spots' show up very well when doing HDRI by the way.
4. (Whispering)...I'm not yelling when I place others in caps...it is just another way to emphasize my addressee...my bad.
5. Do you own a D600? If you did, I would think you would understand how frustrated it is to go out and upgrade your system from DX to FX and spend almost $4,000 only to find out that, ...it....doesn't....work...right.
