Dodger,
I have used Steiner's for about 15 years now. I have the 10X50 Military style. I've enjoyed them over the years and they are certainly better than the 10X50's I was using prior (Bushnell) but they do have some problems.
As Bull said, the smaller objective lense will fail sooner in low light than the 50. I hunted with a guy who had the 12X56 Steiners. One day we saw some deer in the shadows at dusk. I could see them but couldnt tell if there was a buck or not. With his bino's you could clearly tell that one was a buck. His had more magnification, but it was the better performance in low light that helped the most.
As for the individual eye focus, I prefer that because not every ones eyes are the same, particularily if you wear glasses. One eye might be 20-20, the other 20-15, for example. The way Steiners are designed is once you get each eye piece focused, they are set and good for 20 yards to infinity. Thats why there is no center focus knob.
Again, Bull's friend is correct. Steiner just doesn't seem to think people will want to use their binos with a tripod. Finding an adapter is a pain. Everything you get will have to be an 'after market' item. But I mentioned this before.
Just one Steiner owner's thoughts....
