Finally got around to using them a full day, and I enjoyed them alot. Optically it leaves nothing to desire, mechanically there is one flay: the eyecup rotation. They have a few click stops, but the final position doesn't click in position. There is a little bit of play from fully retracted end position to first click "barrier", don't know how else to describe it. And between the click stops (and so from fully retracted end position to first stop) turning resistance is very low, so when using the eyecups tend to twist a bit inwards by head movements. In practice it is not a continuous nuisance, but I did encounter a few times I had a bit of kidney beaning (eye relief is júst right, eye positioning the same, can imagine for some a bit tight) and found the eyecups rotated inwards just a tiny fraction. It's really just 20-30 degrees play, but it's there and something to change in a next batch, I would say. End position should be full stop, in my opinion (and experience from other bins). But that's the only minus I could find. Light, bright, sharp, nice warm colour fidelity, handling and focus knob are perrrfect, it's really an awesome set of bins
