[yannisgoossens]

I hate that , that sound of a broken lense

[Kallasolle12]

[jclspedding]

oh dear...

[Revoltingsheeple]

My lens looks completely different, but regardless it's definitely not that loud! Have you been forcing the focus while it's in auto focus mode?

[MilosBencic]

if that sigma have a af motor is that what makes this sound broken...

[prmass1]

You have the older generation APO from sigma. Probably its been abused and used up. If you don't want it send it to me.

[Calrlito]

i want to buy one for my sony what do you think?

[anycall25]

man, it just happened to my yesterday! i should have listened to the other people in the forums..

[piapple]

my 70-300 sigma is worse! the noise is louder using AF mode. It sounds like it is scratching metal with a high pitch noise on top of the noise your lens is making.

Do you know what is the problem?

[mmatasic]

what's that noise???
