Originally posted by Blacknight659 Hello all,
I purchased a Pentax 16-50 DA* off the bay, and moving the zoom ring seems abnormally stiff from 28-45mm. The lens does zoom, and seems to be ok otherwise, but it isn't comparable to my other lenses or my DA* 50-135.
Should I be worried about this? Does your copy have a stiff action in the zoom range?
Mine does this to. The zoom will probably break.
I live in a country with basically nonexistent servicing, and I could manage to fix it by my own.(I do a lot of DIY repair in mine equip)
Like some already said, a very little and tiny and fragile plastic index tab connects the ring with the helicoids of the zoom group and are quite prone to break. A very fragile and bad engineering in my opinion.
I did relpace it with a custom made steel index tab and now are working good.
I recomend you to take it to service right away, because if it is already that stiff, it'll break soon. And mostly in a situation that will piss you off.
But if you could return it or make some sort of compensation, give it a try with the seller.
