I would like to know if anybody has used a plastic film protector on their DSLR LCD screens. I have read that some work and some don't work. That they are a pain to put on and trying to keep the bubbles out when applying. So who has used them and which brand did you like? Are there any that are anti-reflective? Have any of you scratched your unprotective LCD screens when using your cameras?
There are expensive film protectors, but in my experience, even the cheap stuff does the job just fine. You know... plastic film isn't going to help much if you smash your LCD into a rock, no matter how expensive it is... but the cheap stuff will protect against ordinary scratches just as well as the expensive stuff. And, frankly, you can by a whole package of sheets for a couple bucks... you can afford to replace them each month if you feel like it. The only difference, perhaps, between the cheaper brands and the custom, "made-for-your-camera" stuff is that you'll probably have to cut larger sheets of the cheap stuff down to size in order to get it to fit your LCD screen perfectly. It's pretty simple, really.
They aren't the most painless thing to put on properly... bubbles, as you mention, are the most prominent problem... closely followed by getting fingerprints on the inner side of the film. It's all in the application technique, which may take a few tries to get right. I wouldn't call it difficult, there's just a small learning curve.
I don't personally use them on my DSLR, since my D5000 has an articulated display that can actually be flipped around for protection. I have used them on various cell phones and iPods, though. I always make a valiant effort to put them on at least once when I first get an item, but I've never had the best of luck with them. They protect really well while they are applied... but it seems that no matter what I put them on, the film inevitably begins to peel off at the corners. At that point, if you don't replace them, the peeling will continue until they finally fall off or begin to detach enough that they are bothersome when trying to look at the display (in which case I just peel them off).
As far as anti-glare, I'm sure that there are plenty of options... just keep in mind that, more likely than not, they will eventually peel off no matter what you pay for them. It's much less disconcerting to have 50 cents worth of plastic peel off than $10 or $15 worth. I recently got a "custom cut" plastic film cover for my iPhone 4... cost me $15 or $20. It lasted about two weeks before I pulled it out one day to find that it had peeled on one corner when I put it in my pocket and lint had plastered itself all over the detached corner. That's $20 down the drain... I wish I hadn't bought it.
