I have used the earliest version Nikon Venturer 10x42LX (part number 7346) and its factory refurbished replacement Nikon Premier 10x42 (part number 7536R).
Sharp across the entire field but as not as razor-sharp in the centre as the best porros and the European competition. You feel as if you have moved closer to the picture seen with the naked eye: this is the ultimate accolade for viewing comfort, even with spectacles. Colours in 7536 are more neutral than in 7346 which had the faintest reddish tinge. "Rolling ball" effect when panning. Reduces with extended use. Chromatic aberration is visible in high contrast situations, partially related to positioning of eye relative to oculars. Smoothest focussing wheel movement of any binocular, moving from minimum to maximum with the shortest of rotations. For older users with declining eye accommodation, this promotes focus overshoot and impression of narrow depth of field. Ergonomic body design with impression of great durability.
