Ok - the pricing on the Leica 10x42 Geovids has gotten me interested in combining my rangefinder and binos into one unit. I currently use a pair of Leupold Mesa 10x50s and get pretty good low light resolution, but a bit heavy. My ranger is a Lieca LRF 900 (big boxy thing). I will seriously reduce my weight and stuff carried if I switch to the Geovids. Question is, will I give up lots of capability on the bino side if I go from the Mesas to the Geovid? The obvious thing is that the Mesas have 50mm objectives and the Geovids are 42, but does anybody have any real experience with this move? Thanks!!
