s you have used the Nikon 8x42LXL glasses for some months now, perhaps a more systematic review would help Birdforum readers. Could you set down your perception of the glasses on these counts:
i)Sharpness in the centre of the field and across the field(edge sharpness)
ii) Brightness and contrast: the luminosity of the image and the ability to distinguish between delicate differences in colour or shadow; picking out skulking birds in hedges or rushes at dawn or dusk;
iii) Lack of flare from angled sunlight or reflected sunlight;
iv) Perceived width of the field; ease of view and whether there is a perception of having moved closer to objects viewed without there being any intervening glass;
v) Lateral chromatic aberration and the extent to which it annoys you; does it prevent you from identifying a bird which you would otherwise have identified on colour alone?
vi) Ease of use: does it allow fast dioptre alignment with the moving right eyepiece? can you adjust dioptre, inter-pupillary distance and eye relief (by raisng of lowering the eyepieces)quickly?
vii) Do images, especially of moving birds, snap into focus; does the fast focus lead to focus on points beyond your target; do you have to adjust the focus wheel when shifting between objects which are relatively close to each other or do they remain in focus?
viii) Does rolling ball persist when scanning or does one get used to it over time?
Seems like a tall order but it might worth the time invested in writing the relevant paragraphs.
Best wishes,
