I purchased my D800 about a year ago (shy one month) and had to get in line to purchase it. I too was concerned about some of the stuff I heard from early buyers online. I called Nikon ... they explained their warranty to me, addressed my concerns and I put my money down.
Almost one year later, 12K images, and more joy than I have ever experienced with any purchase I have ever made...
1) no left focus issue, no right focus issues and I haven't gone blind yet from over doing it!!
2) no rubber issues.... no grip issues ... come to think of it, just holding and looking at the D800 is pleasure enough
3) no green screen, no green men from Mars, not much of anything to complain about
4) my only beef, not enough frame rate per second, but I knew this going in. You are in Fashion? You have no worries.
5) my current nit on top of #4 is I wish the buffer was a tad larger. Long bursts will slow the camera down until the buffer clears.
I have spoken to a lot of sales reps in a lot of camera stores in the last year. In recent memory, they have NEVER experienced demand for ANY camera, like they have for the D800. NON... NADA...NEVER.
So, a CANON shill comes online and gets a rumour going that you get Radiation Poisoning if you use the D800 more than 5 minutes a day.... really? LOL who cares.
I think you should wait until Nikon corrects this problem before you buy!
Get the idea.....
Go buy the camera, start taking pictures ... you will simply not believe your eyes! There is no finer piece of DSLR equipment on the market today, in my opinion. Forget the pure, unmitigated BS you are reading online from nay-sayers.... the D800 turned the photographic industry on its ear, last year!
PS: Purposely chose this image because it has YELLOW in it!
Also, yes, some people had issues. Compared to the number of cameras sold, this is perfectly expected. Some people will have issues with almost anything they buy. It is the law of averages. Read the stories and reviews from the POSITIVE posters online who actually OWN the camera and deep 6 the nay sayers and Bullsh*ters.
