I also own the Pentax DCF SP 10X43's. They are very nice and in my opinion, the best new bino for the money.
A friend and I were spotting an elk under a brush last fall - 4 point raghorn, I was using my Pentaxs and he had Swarovski SLC 10X42's. The bull was about 1 mile away sleeping under a big bush. We would look and swap binos back and forth and I personally could not tell any differerance in the view or amount of detail between the two binoculars.
I bought mine on a closeout deal at Sportsmans Warehouse for $450 a far cry from the $1150 for the Swarovskis.
