Sigma 'zoom creep'

[EdT]

I've just got a sigma 18-200mm lens of e-bay, for a reasonable price. I'm very happy with the lens apart from one thing.. when the lens points down the weight of the unit causes it to extend out (towards full zoom) I believe referred to as zoom creep. Should this unit do it? It does have a lock slider; but this operates only when zoom is fully retracted.

They all do that, sir!

Hi Ed


I'd be surprised if it didn't after a little use. I bought a fellow PHer's 70-300 and he commented that it didn't suffer from this - but after a reasonable amount of abuse from me, it's loosened up nicely Doesn't effect the image (well except if you're on a tripod pointing down I suppose) but is a right PITA.

I think it'd be a feat of engineering beyond "reasonably priced" zooms to expect otherwise?

Hello!

You're right.. it IS a bit of a PITA. I'd prefer the whole mechanism to be firmer, so by giving less creep; surely wouldn't be that hard for them to engineer?

Only thing is it'd then push the price of the lens up. Also you'd find the lens is consequently heavier and people would complain about the weight.
