Message: <blockquote data-quote="John M Robinson" data-source="post: 1728522" data-attributes="member: 61814">I live in snow for at least four months of the year, and we have black horses in our pasture, so I have a pretty severe test of CA right in my backyard. Of the bin's I use regularly the worst are my 8x42 Ultravid BRs and the best are my 8x32 SEs, though still visible. I also have 20-10 vision and as I work in design, I am very tuned into colors, so CA does bug me. That said, in normal, no snow viewing against a background of foliage, my Ultravids seem exceedingly sharp to me, and in the rare instance I see CA out in the field, I can pretty much null it out by centering the object.BTW, my 10x42 SEs are much worse with CA than the 8x32s, about 60% toward the Ultravids from the 8x32 SEs.John</blockquote>
