Thank you all for the kind comments!
I forgot to mention, all the pics were taken with my A700 + Sony 18-250mm in RAW format and then processed with DxO. BTW, the A700 worked fine under heavy snowfall and rain; the only issue I went into was the second day after several hours of being wet and cold the inner part of the LCD screen fogged quite a bit, but at the next day it was OK and that didn't happen again for the rest of the trip
It was a long 21 day trip... mostly for trekking, some days we walked +30km and that wasn't really the best way to take photos... I make this trips to the south every year, but I'm thinking maybe the next year I'll be walking less and taking more photos

I wanted try low light photography, but unfortunately the weather didn't helped. It rained 17 of the 21 days, but it was a great experience anyway.
