Sorry to dig up an old and seemingly resolved thread. I've ben following this (and others, perhaps) because I've never had a loupe that really satisfied all my needs. Smaller 4x loupes worked with some cameras but gave me fits with cameras that had hoods. Yes, I could always remove the hood but like them for GG protection when not in use. So looking for a vintage loupe and frustrated because of cost and that most are in Japan. So opted to try a new made-in-china loupe, eTone 6x. For under $100 received a really well made loupe that really works great for my applications. Adjustable focus; rubber ends; metal construction; clear glass... and a neck strap too. There are several eBay vendors (who I think really might be the same organization using different names) - some shipping from China; others shipping from Kentucky. Delivery time was about 7 days from order.
