My wife and I each have 10X42 Vortex Diamondback binoculars. I use to work for a big box outfitters store and spent a lot of time working with manufacturer reps and customers. We carried Vortex, Nikon, Zeiss, Swarovski, Steiner, Bushnell, Leica, Leopoldo etc. I spent a lot of time talking with customers about different features, manufacturing processes and clarity.
One of the most important point was talking about customer support and warranties. Many of the manufacturers have good customer service but the lifetime warranty from Vortex is huge. No warranty to send in. No questions asked. Lifetime warranty on things like waterproofing, anti fogging etc. I lost one of the lens caps for one of the objective lens. My fault, I should have been more careful but I could not find it anywhere.
I emailed Vortex and had a pair of lens covers for my specific model in my hands in less than a week. No questions asked and no cost, when I sent my original email, I offered to purchase the replacement (my fault) and they would not take payment.
The quality of the binoculars are top notch. Best value. No regrets. Go to a store where you can walk to a window and try different models and manufacturer’s product. And find a sales associate who knows the products.
Good luck
