You're welcome! The Traveller ED is actually a roof, but Opticron sells a variety of porros, some of which have high ER. Opticron bins are made in Japan, others in China. The prices reflect that but so does the fact that porros are less expensive to manufacture.Brock, thank you very much for your research and for sharing this info. I will most definitely pick some up and test them, next time I'm at a retailer who stocks them. And who knows, it may be the beginning of a porro journey...🍻
Chinese optics are "Getting Better All the Time," but I've found that Japanese optics have tighter QC.
