I have no prior or current affiliation with Expert Shield UK. ExpertShield UK approached me and offered to provide a review sample; I accepted this offer, and agreed to conduct both my original review and this follow-up.
This is a follow-up to my earlier review of the ExpertShield Screen Protector for the Olympus OM-D range of cameras. The test sample I am using has been fitted to the camera for over six months. I aim to concisely revisit my original comments, to see if they have changed in the time the screen protector has been fitted to the camera.
Fit, Finish and Touchscreen Operation
The fit and finish of the screen protector remains very good overall. The silicone-based adhesion system in use by ExpertShield has held the protector in position, and there does not appear to be any residue seeping out around the edges. Two small bubbles have appeared (at the top left edge and the lower left corner of the screen) under the screen protector. In practical terms, the bubbles are of no concern, as they lie outside the viewing area. These bubbles have not compromised the attachment of the protector to the screen, either, which is more than can be said for a number of other screen protectors I’ve encountered.
The “frosty” appearance I noticed under some lighting conditions when the screen was off, has disappeared entirely. The exact cause of this when the screen protector was new remains a mystery to me, though as I stated at the time, it made no difference to viewing when the screen was active. On the topic of viewing, the protector is still incredibly clear, with no negative effect on colour reproduction or viewing angles.
Touchscreen operation is still effective, with no lag or compromise in finger tracking ability. Accuracy when using the touch-to-focus function of the camera remains high.
Fingerprint, Water, Temperature and Scratch Resistance
While fingerprints accumulate as they always have, they are still as easily removed as they were when the protector was brand new. The protector has also maintained its water-shedding abilities; being subjected to several downpours, including a half-hour in monsoon rain, no negative effects have been experienced.
Since the first review, I have had the opportunity to test the screen protector in extremes of temperature, from below-freezing Central Otago to warm and humid Cambodia. In each case, the protector showed no signs of failing, and there was no compromise of function at either extreme of temperature. However, I believe the heat has potentially contributed to the appearance of bubbles on the periphery of the protector.
Before moving onto the scratch resistance proper, I would like to proffer my definition of scratch resistance. Scratch resistance implies a reduced likelihood of, or severity in the case of, scratching. This differs from being scratch proof, which implies a total inability to be scratched.
Bearing in mind my definition, the scratch resistance still appears to be there, though the surface of the protector is marked with a multitude of hairline scratches. This has been caused by the handling the camera was subjected to: being cradled around the screen in dusty and gritty conditions, and pelting up against the zipper of my waist pack and buckle of my belt. Given that the scratches are very shallow, and do not appear to have penetrated the protector to the underlying glass screen, the ExpertShield screen protector has performed its most fundamental task of protecting the screen.
When compared to the PEN Mini I was using without a screen protector, scratches are fewer in number with the ExpertShield, and of noticeably lesser severity. The same observations are made of the ExpertShield versus some other screen protectors; I am currently surveying a competing screen protector which is littered with deep scratches, pockmarks, and even a few gouges, which are deep enough to hit the screen that it is supposedly protecting.
After more than six months in my hands, the ExpertShield Screen Protector for Olympus OM-D still performs as advertised: it offers unobtrusive, durable screen protection. While bubbles have appeared beneath the screen protector, they have not had a compromising effect on the integrity of the screen protector. I anticipate that the screen protector currently fitted will last until my OM-D is upgraded (in three years).
Based on my experiences over the past six months, I maintain my original recommendation that the ExpertShield screen protector is an excellent means of protecting the investment you have made in your camera.
The Expert Shield for the OM-D is available at http://www.expertshielduk.com/olympus-om-d-e5-expert-shield.html. They are available in standard (as discussed here) or anti-glare types. Both types are available for a multitude of devices listed on their website.
Special thanks to Ed Tyson of ExpertShield UK for providing me with the opportunity to test this product.
