Hey Ron, How are you getting on with these screen protectors? had a chance to test them in different scenarios and find the best yet?
Im looking for a screen protector for my 503 (as a low mode monitor) and the descriptions by Small HD aren't very detailed;
"The Ultra Matte is flatter/less glossy screen then the Pro K, the Pro K is also slightly warmer than the Ultra Matte. The NuShield DayVue is a better option if you shoot in sunny outdoors, similar to an ND filter that is slightly warm as well."
