Pentax D FA 15-30mm/f2.8 Zoom Failure

Can anyone advise incidences of the zoom control knob completely locking up on this lens? I just rented this lens from LensRental and the copy I received the zoom controls completely locked up after less than 5 minutes of initial testing. The nice folks at LensRental did immediately sent out another copy next day FedEx (shout to LensRental, thanks!). I am considering the Pentax 15-30mm/f2.8 or the Venus Laowa 12mm/f2.8. I have already tested the Venus 12mm as a rental and was not at all impressed with it's edge performance on the lower edges from my particular lens rental copy. I suspect the lens was mounted off center. I have not eliminated the Venus, if I find a decent copy. My initial testing with the Pentax is that its edge performance is very nice with some edge CA wide open with the CA virtually gone by f8. BTW: The Pentax 15-30mm front lens is an impressive work of glass and I just wanted to hear anyone who can report similar locking zoom issues. Comments about the Venus 12mm would also be appreciated. These are being mounted on the K-1. Other zooms I have include the D FA 24-70 and the D FA* 70-200 and a multitude of FA and FA* primes.

It’s very possible that the previous renter(s) of that lens damaged it. That would be my guess before assuming any quality issues with the lens.

Faulty lock switch perhaps?
