My K-70 body was received in late December, with planned first real use the first week in January during a family trip on the North Shore of Lake Superior in Minnesota. Today was the first day the high temp reached above 0 degrees F. First day of use was near the Canadian border at 24 degrees below 0 F., without windchill factor. Though the K-70 was kept under my outer layer when hiking, it was out frequently. The K-70 performed flawlessly, faring much better than my fingers.
I used my DA 15mm almost exclusively mainly because it was too darn cold to switch to my DA 40mm! Seriously, I would have likely switched minimally anyway as the subject matter was scenery, usually frozen waterfalls and ice formations along Lake Superior.
The purpose of this post is to thank all on this forum that answered my many questions and provided pertinent opinions leading up to the purchase of my K-70 and 2 lenses.
I wish everyone a great 2018!
