I researched these from various sites and concluded that they were the one to buy for my wife's camera. Bless her, she's a nightmare with cameras. Always carries it, but in the deep dark myseries of her handbag, along with all the other sharp and unfriendly items that wreak havoc with her camera. The new camera replaced a previous Sony that looked like it had done two tours of duty in a war zone!
With this in mind an 'industrial strength' screen protector was on the shopping list.
These screen protectors are not easy to buy...only available on Amazon and frequently out of stock. A tribute to their popularity and effectiveness.
Having got hold of one I was a bit wary because of reviews saying it was difficult to fit. Now, either I'm either very skilled (unlikely), or very lucky (not usually), but I found this a doddle to fix. It just seemed to float on in one go....wow! Difficult to see that it was there and a significant reduction in reflections without dulling the image.
The camera has started it's first tour of duty in the 'bag zone' and after a few weeks seems to be unmarked.
