Broke mine today! Was stuck on 35mm and I tried pushing in through like I have had to do lately. Something broke in the focal length controller and it won't work anymore. I have to keep it on 55mm to shoot (pull it out if it is not already there.)
Have to send and pay for it to be repaired now. Would not recommend this lens based on it's poor build and obvious design flaw. Not fit for purpose, as described and built to last a reasonable amount of time.
