Is anyone savvy on the new Swarovski SLC Binos, the new model # is 58310 for the 10x42. Some web sites show them as HD and the price is $1799. The previous price on the 58210 model was $2249. I was just checking to see if anyone knows the differences. The 58310 model was just released 10/13/13/ Sounds like a lot better price if the binos are HD and comparable. Any info is appreciated.
