[QUOTE="azarcher10x, post: 1893098, member: 57286"] The 10x42 are smaller, but what you give up in size, you lose in gathering capabilities. Remember the human eye will dilate to approximately 5mm. If you do the math, the 10x42 only give you an exit pupil of 4.2mm. Your eye can handle more light than that size binos are capable of. In 10 power, you want at least 50mm objective lenses for best light gathering. 10x54's give you even more, which in low light, makes it easier on your eyes. It's also important to have the best quality glass and coatings. If you will be spending a lot of time behind them, I would rather have high quality 10x42's, than cheap 10x50's! The Zeiss 10x54 RF are the best glass you can get in binoculars, plus you get the rangefinder. Compare to straight binos, the rangefinder will technically lose a couple of percent of light transmission due to the rangefinder, I can't tell [/QUOTE]
