I had an opportunity to try some out the other day. They were the 10x42's and though they were real nice, I was comparing them to the Cabelas Alaskan Guide binos and they were edged out in low light. The Alaskan Guides were a bit brighter at dusk. I also had with me a pair of Swarovski 10x50's, though not an apples to apples comparison on field of view, still there was no comparison as far as crisp and bright. The Swaro's were definitely better glass.
In my humble opinion, the Pentax were close enough to the Alaskan Guides that price would have made the call for me....but the Guides were not only a little better, but cheaper as well. Pentax compared to Euro glass.....well, in this case the extra bucks for the Euro's get's you better glass, no question about it.
I'd recommend that you do as I did. Find some friends and neighbors with all sorts of binoculars, lay them out on the hood of your truck (the bino's) and try them out in low light. See what YOUR eyes seem to like best.
Hope this helps!
