I'm not a big fan of the glass ones that adhere to the screen because they are difficult to remove if you break them. Since they are so thin, a minor pin point impact will break the glass, and possible damage the camera's built in protector. To remove the broken glass, you often need a hair drier to heat it up for the adhesive to release.
There might be some out there that don't break as easily, or do not require a hair drier to remove, but I really haven't looked into it much. I use the Kenko multicoated screen protector on my D800. It's a thin plastic protector that guards against fine scratches. The Kenko kit contains one for the top and rear screen.
You boys might do well to READ the description on the link Gotta say WTF
Product Features:
High Light Transmittance. Uses a 0.5mm ultrathin optical glass with at least 90% transmittance.
Super Abrasion.Made of Hard and Durable Glass prevents the LCD Screen from being rubbed and scraped
Super Scratch-resistance. With the explosion-proof film, it will not damage the LCD screen at all.
Easy to install and remove. The frame design of black ABS can match well with the camera.
Oh, it don't block sh*t. Why would we RECOMMEND something if there were issues Wow! Lazy, don't begin to cover it...
Hey Will,
Actually my only real concern isn't answered in the link.....
" Can you still see 100% of the screen with the protector snapped on?"
That's a reasonable question - don't ya think?

I used GGS on my D700 and really like it, much better than Nikon's own screen protector.
You should get the protector exactly designed for the particular model. I got a D800 one for D600 (I just need that for a trip and D600 one was unavailable..I thought their LCD size are the same....). The package should include 2 piece of glasses, 1 for big LCD monitor and 1 for the small LCD panel.
I don't break my screen protector every now and then so I don't worry too much about removing it. They are supposed to be harder to break than the stock one to begin with.
They use 3M adhesive, actually not that difficult to remove.

Yep, GGS here too. Super nice looking, easy to install, and if need be you can remove them with some dental floss. Also they include a protector for both LCDs, they rock.

No, tempered glass was first offered on the D3 series and now the D4.
Is there any information by Nikon to say that the LCD on the D800 isn't (or is) tempered glass also.
Never used a protector on my D3 and have never scratched it and so far the same goes for my D800E. However, if the latter doesn't have a tempered glass LCD then I may invest in one.
GGS all the way on all my DSLRs that I've had as well as my LX-3, LX-5, and now LX-7.
If it's scratchable I'll scratch it. My GGS protectors have taken some good hits and survived just fine. When applied to the LCD it's something I just don't have to worry about. Peels off pretty easily using a credit card or some other thin piece of plastic.
Yes the LCD on today's DSLRs (like my D800) is replaceable, but I'd rather replace a $9 part myself then have to send it into Nikon for $100+ replacement.

Zesto,
After checking into this, I can say that I don't know. Nikon doesn't advertise "tempered glass" monitors. Couldn't find any Nikon reference to tempered related on the D800 or D4. Check the D4 user manual and it doesn't mention tempered glass either. So, I don't know and therefore take my previous comment back. I'll probably put a GGS on the D4, since it is cheap and move on to other big problems.
I use the GGS III snap on screen on by D800 and it is quite good. You can see 100% of the image as it does not blank anything out. The beauty of the snap on screen is that it can easily be removed and sometimes you have to remove it to see critical image quality as it does compromise the IQ coming through the screen. For me it is only just better than the plastic screen protector supplied by Nikon.
To put it into context, if you said that the screen bare was 100% and the Nikon plastic cover was 85% as good, then the GGS screen falls somewhere in the middle between the two. I would not be without a screen protector and the GGS III is the best compromise, IMO. This is just my opinion.
Does this keep dust and sand from getting between the cover and the monitor? It looks very similar to the stock protector Nikon provides, except the black trim.
