As a Navy and Marine Corps veteran and lifetime outdoorsman, photographer and hunter, these are the best binoculars I've ever used. I own 8 Canon 'L' Series lenses for my 7D, and I have a pretty good idea of wha 'great glass' is and isn't. Leupold gave me 'Great Glass' in these 10x50 Olympics in Camo! After dusk, my 59 year old eyes couldn't see much, but with these glasses I spent an additional almost 10 minutes watching a Bald Eagle atop a tall Cypress tree across a field some 250 meters away surveying the lake behind us for a last meal tonight. H looked close enough to touch. I could see feathers in some detail! I could se ehim turn his head from side to side and could see his eyes as they paused on me and then went back to searching. Hand holding was doable with some elbow bracing on my body, but that was due to the magnification and not the weight. I wished I'd gotten the tripod mount I just ordered and I'd still be watching that bird! I'm not a 'birder', but I can see where a birder would love these too! In brushy shadows around the lake up to 300 yeards away, these really do make late dusk as bright as 30 minutes earlier, and allow some real detail for hunting early or late. I bought these as an upgrade to some Nikons for a trip in the Navion to the Grand Canyon next month, and WHAT an UPGRADE! I've used Leupold (and Nikon) scopes on guns and pistols before, so I expected a lot, .... and I got alot more than I expected. That being said, objective lens caps need upgrading, Leupold!
Pros: Clarity, Light gathering, Color, Lightweight, Strong....
Cons: None that I've seen.
