Anyone here have one, and if so have they had any issues with the focus wheel?, asking for a family member, the focus seems to take more than the normal turns to and from infinity. I found out that Land Sea & Sky works on them now, Swift has delegated service of their glass to them.
I tried them out, and the on-axis resolution was very good, the FOV is a bit slim at 6.4 degrees, but is is an easy glass to handle and seems to be well made.
