If you have much experience, any small difference in weight is not significant at all. The older Swarovski SLC models excel in optics and they were a little heavier than some others.
The Meopta does very we with their newest HD models, similar to the Zeiss Conquest HD, very good values.
Meopta’s Meostars are hard to beat for the money. Their only downside is the weight. Real glass, in this case fluoride glass, is heavier than coated polymers. This was discussed at length yesterday at their booth, which ranks as one this weeks best visits. They’re working on a second generation “B2” Meostar binocular, but are still a year or two out. Meopta’s folks aim to trim weight without sacrificing optical quality and durability. Great people.
The 12x50 Meopta is 2.4 ounces heavier than the 12x50 Swarovski, 37.4 and 35 ounces, respectively. I guess you could call that a downside.
You don't buy optics based on weight, the optics are similar, and the price is double with the Swaro. I suppose you should know that.
And by the way, I am a Swarovski fanboy...
