Welcome to BirdForum, the internet's largest birding community with thousands of members from all over the world. Good coatings on the lenses and the prisms can in some cases double the amount of light that gets through the binocular, when compared to those that have none or poor quality coatings - As we have already discovered, these Carson 3D Series binoculars use good quality coatings and glass that help to transmit more light to your eyes and therefore produce a brighter image than inferior binoculars of the same design and configuration. To test for signs of color fringing, I focus on light coloured and white objects that contrast greatly with something in the background and look at the edges of the light objects.

Good light gathering ability is important because quite often you will find yourself in situations where the lighting is sub-optimal, especially in thickly wooded or forested areas, early in the morning just before or at sunrise or late afternoon when most birds and other animals are at their most active. The Carson Optical VP-250 12x50mm Compact Binocular has been designed to be the perfect binocular for any outdoor activity. these are up there with some of there lightest pairs of full sized binoculars that I have ever reviewed. But no matter how much light your binoculars gather, it is no good if that light is not passed onto your eyes ( transmittance) and this is where it is important to know that not all 10x42 binoculars are created equal as the performance of a pair of optics in poor light depends hugely on the quality of the glass and optical coatings and not just the exit pupil and twilight factor formula. All 3D Series binoculars are of a roof prism design featuring high quality components and optics including fully multi-coated optical elements and Phase corrected BaK-4 prisms that give a sharp and high-contrast image over the full field of view.

Get a pair of Nikon Monarchs or Vortex Diamondbacks if you want, I totally understand the temptation, but they won't outperform these.

Those who indicate that they could not fit the strap and camera into the case together just don't know how to wrap a strap around the middle of the barrels – then everything fits snugly into the case. These phase correction coatings counter this by keeping the light in the correct color phases and therefore produce images that have better contrast, a higher resolution and improved color reproduction.

The body on these Carson 10x42 3D binoculars are O-ring sealed to make them fully waterproof which obviously protects them from moisture, but also prevents dust and other tiny particles from getting inside them, which can lead to your view being spoilt.
