First time poster here. I have the opportunity to purchase either a NL 10X42 or a NL12X42 Swarovski binocular. I am a bird watcher and primarily a mountain hunter. I will get the Outdoorsman's stud for the tripod adapter capability and the Swarovski head rest. My question is for those that have had the opportunity to look at both models and it is this: does the artificially adjusted parallax view of the 12s which is more than the 10s outweigh the benefits of the sharper center sweetspot image of the 12s. I wear glasses and eye relief is similar in my view in both units. I do not use the stops on the eye pieces but almost go glass to glass as I prefer the corrected view of my glasses to adjusting the binoculars for my eyes. I do a lot of hiking and watching in the alpine so magnification is a plus. The 10s seem to produce nominally less eye strain. Both have because of the increased sharpness and increased level of hand shake but I am pretty steady with a decent resting heart rate of approximately 54bpm and I am 52 years old. This will probably the one unit to use for the rest of my life and I have many other binoculars: 10X42 SV FPs, 10X42 SLC HDs, 10X42R Leica Geovids, 18X56 Vortex UHDs, 12X50 Vortex UHDs, 10X42 FL*T Victory, 8X30 Swaro CLs, 10X25 Swaro CL Pockets, 8X30 Glantz, and 8X32 Conquest HDs. So what would you folks suggest. The 10s in my opinion are softer on the eyes but the 12s do have a striking image. Softness is a difficult to quantify element that certain binoculars like the SVFPs, the Leupold GRs, the Victory FLs and the old Zeiss 10X40 Dialytl binoculars have. It is kind of a curvature that allows the eyes to relax to a degree that allows them to use the binoculars for hours after hours.
