A piece of PDA screen protector film cut to size does the job perfectly adequately and is much cheaper and easier to obtain. You are not looking at the screen on the back of the D40 you are looking at the built in screen protector which, if the D50 is anything to go by is very robust and abrasion resistant. The actual LCD screen is well protected out of the box.
Macnut, I've bought and tried perhaps 8 or 9 different screen protectors in my quest for the perfect unit for my D40. Here are my observations. Keep in mind that what I was looking for was a product that would enhance LCD viewability with physical protection as only a secondary requirement. Your requirements may vary.
Target Performance Characteristics: 1. Antireflective properties roughly equivalent to that found on prescription eyeglasses or high quality lens filters. 2. Scratch resistance at a level high enough to resist scraping contact with fingernails, plastic zippers, hard plastic parts, wood. Some resistance to metals and minerals is preferred. 3. Application method that robustly prevents the ready inclusion of air bubbles, wrinkles, etc. during installation.
Obseravations from testing commercially available products: 1. None of the products I've come across offer effective coatings-based AR 2. Many products targeted at the PDA, celphone, portable game console market have adhesive coatings that are less than what I'd consider "optical quality" exhibiting streaks, bumps or other artifacts that negatively affect image quality 3. The thinner the plastic film that is used as the substrate, the more likely the user is to encounter problems with application such as bubbles and creases 4. Water repellent performance is a red herring as most hardcoatings are silicone-based and thus by nature will cause water to bead 5. Hard coatings will protect from low angle scratching but not from direct impact (which is determined by the hardness of the substrate film 6. Products that use adhesive tape around the periphery of the screen eliminate bubbles but require a much more precise application technique.
The best protective product I've encountered is the DaProducts. These are thick, tough and not terribly difficult to apply.
The best "AR" product is one made by Pelican for the Sony PSP portable game console. Like others which offer genuinely effective glare reduction, it is not coatings-based. These units offer a texturally matte front surface which effectively reduces specular reflection, which is what is perceived as glare.
The best "feelgood" product is the Giotto's Aegis series. Even the generic sizes look and feel professional grade. Sadly, AR performance is poor.
The Screen Patronus product is actually a pretty darn good compromise across all properties. And it's cheap too.
I hope this helps more than it confuses.
Disclaimer: I have not tried every possible product out there so my information is necessarily incomplete.
I too have the da Products LCD protector for my D50. Just got it a couple of weeks ago and put it on in ~5 minutes. I had my D50 for over a year and never scratched it, but thought I should do something just to ensure it would remain scratch-free!
I bought the DA Screen Protector but I found that the orange peel-off strips were a problem. The orange transparent strips would either peel off without the white backing, or the white backing would not separate from its adhesive part. I may be mishandling the strips but frankly, I find the procedure unnecessarily fussy.
The EXIM SPUC screen protectors are the best I have ever found. They are difficult to find, but a quick search on eBay found several specifically pre-cut for the D40/D40x.
I have one on my D50 and love it. It provides no color shift, is very clear (EXIM claims 99%), and it feels smooth. I also love the way it is installed . . . there is no adhesive involved. You just put it on and it stays. Really impressive is that you can easily take it off for cleaning (I haven't needed to in a year), and reinstall it.
Oh, and the EXIM SPUC comes with a pre-cut protector for all screens on the camera. Of course, for the D40, there is only one, but for the D50, I received 2. Very nice.
I recently bought a multi-coated glass LCD protector on eBay. It went on in an instant and looks just great. I just searched for Nikon D40 LCD protector. The store name is John's Camera. Paid $15.00 w/free shipping from Hong Kong. Shipping takes about a week. This is a quality product. It uses a 3M adhesive. Glare is reduced as a secondary benefit.
