Due to pretty drastic problems with my eyes earlier this this year I felt it was necessary to have a rethink on my optics. I was very happy with my little 8x32 Countryman roof bins but really needed something to let more light in and maybe up the magnification. I spent hours looking at test results on the web and received a lot of advice from a couple of regulars on this forum I ended up at my local Opticron dealer. After trying a big number of models and still being a porro fan at heart I opted for a pair of Imagic porro 10x50 despite them looking a bit dated in these days of roof prisms.These have served me well through the spring summer birding including a great few days watching Golden Eagles and Harriers on the Isle of Arran. On our last couple of outings in freezing conditions they have become very hard to focus. I presume this is probably due to lubrication getting very dense due to low temperatures but has any other user come across this problem ? I would not have thought the machining tolerances were so close that near zero temperatures affected the movement and to keep them tucked inside my jacket would not really work any advice welcome.
