Check this out. I finally got around to purchasing a focusing screen for my D600 from the Taiwanese company FocusingScreen.Com. I had read a while back that some folks had installed them with no problems, so I jumped in and got one.
Here's the weird thing. As far as I can tell, this is a standard issue Nikon focusing screen for the FM3A. I haven't tried to install this yet (will try tomorrow), but has this company simply realized that this standard issue Nikon screen drops right into modern Nikon bodies? The website sells this and other type screens for every single modern Nikon camera, and I can't help but feel this particular screen (type K) is the same screen for all of them.
So assuming this will indeed drop right in (if not it was a $100 gamble on my part), why does Nikon not sell these outright themselves for their cameras? This is especially so for the Df. Because if this is so, it's much cheaper to buy this screen from Nikon and just drop it in. It's listed at B&H for $36! If this indeed the case I have to say I give props to these Taiwanese people for having the smarts to capitalize on this. As long as it works I don't care that I spent almost 3 times as much, because who knew otherwise?
Have a look at the images below. The first is everything that was sent with the order, and the others are close-ups of the back of the box and case, where you can clearly see it's a standard issue Nikon case. Your thoughts?
