So, I returned the Composer for the Muse -- I missed the squeeze and bend from my 2.0. The one I got from B&H has clearly been out of the box before, but it looks in fine condition. However, there's a strange sound when squeezing to focus, like crinkling paper.
The 2.0 never did that — is it normal for the Muse?
Still getting used to the larger size; a bit disappointing but overall I think probably worth it for the interchangeable optics. (In retrospect I would have kept the 2.0 and added the Muse for the zone plate, but hindsight apparently has the largest in-focus sweet spot....)
