[QUOTE="Nate Haler, post: 17944, member: 315"] exit pupil will affect your ability to see at high magnification. Divide the objective by the magnfication, or 56mm/42. The result is 1.33 mm, which is certainly on the real small size. Consider that the human eye can dilate to 7mm at night in a healthy youngish person. Explaining why one of the most popular and useful binocular version is 7x50. [img]images/icons/smile.gif[/img] High mag is going to give you a darker image than lower mag. Lots of 1,000y BR shooters like and use the 12-42x56 NF. But the sucker weighs more than two pounds, and certainly won't be a practical hunting scope for low light conditions. I'm with the other poster -- if you think you want to use this rig in the field, then you'd be better off with the 5.5-22 (which also has a LOT more internal elevation). Or, compromise and get the 8-32, which will get you excellent low light performance at lowest power, with a 7mm exit pupil. [/QUOTE]
