Yes, I'm in the USA, not UK.
The Roamer isn't bad at all. It's very similar to the Carson actually, and they're both good. It's just that the Pentax (both the UP and Papilio) are both better in contrast thanks to the improved coatings. The Carson and Roamer both have a more washed out hazier view next to the Pentax.
I'm a photographer and I've been around enough uncoated, coated, and multi-coated glass to spot the differences. The Carson also says right on the box "Fully coated lenses". You can see the difference in coatings pretty easily on the
eyepiece comparison photo above .
The focus wheel on the Carson does sort of bump into me, but a that point my eyelashes are already brushing the lenses so I think I'm close enough already....
