My pair, despite being incredible robust for all types of fieldwork etc., do have a semi-sticky focus. It's caused by the rubber cover rubbing against the chassis and seems worse in warm and humid conditions - when the rubber expands the most I guess. Very minor for me and so variable that I don't notice most of the time.

Interesting. Semi-sticky sounds about right, except this is sticky enough to make it hard to focus properly. I did wonder about the rubber of the focussing wheel catching against something but if so it’s impossible to see where. The problem doesn’t seem to be related to temperature or extended hard use.
Glad you find yours so robust in the field; apart from this hassle I’d have said the same and optically they are close enough to alpha for my eyes. I still recommend them to students but it’s getting hard to justify if they have to be in for repair for six months in the four years since I bought them new.
