Like the 8x42 Yukon Point binocular, the 10x42 model makes for a good all-around, general purpose instrument, but this time rather than a wide field of view, the emphasis is most certainly on producing a more detailed image at longer distances. Therefore these will better suit outdoor enthusiasts, wildlife observers, hunters, and security personnel who mostly operate at mid to long range distances.
The 42mm lenses offer a good balance between light gathering ability and size and when combined with the 10x magnification produce a moderate 4.2mm exit pupil. Whilst perfectly adequate in daylight, it will hamper these in low light when the pupils in your eyes have fully dilated and thus it is not recommended to choose a 10x42 binocular if you are often going to be using your instrument under these conditions. Note: If you do require a good low light performance and a high magnification, the 10x56 Yukon Point will make a better choice.
At 16mm, the eye-relief is more than enough for most users and should still be just sufficient to ensure that you are able to achieve the full image whilst wearing glasses.
Whilst these Yukon binoculars are not specifically designed for ultra close range usage, their minimum close focusing distance of only 1.3 meters is excellent and thus makes them a good choice if you occasionally like to study things like butterflies or flowers.
