Nikon 20mm 2.8D Noisy AF

[captvizcenzo]

I just got my copy of Nikon 20mm 2.8D today. I was surprised when I mounted it on my D90, the AF sounds annoyingly noisy. The video below will show the problem more clearly.



I want to know if this is normal for all Nikon 20mm lens, or it's just me having a bad copy.

Mine is noisy too. I don't let it bother me.

Does yours have the same noise like mine?

Awe it sounds like a Sigma. Lol. Never mind how it sounds I want to see pictures.

The pictures it produces are totally fine I guess. I'm just wondering if all Nikon 20mm behave like this though.

Pretty much the same. I went and tested it before my first response.

I really hope this is normal.

As the previous contributors have stated, let the sharpness of the images speak for themselves. Mine is the same, I'm not too concerned.

It sounds like some half-arsed night club singer doing a cover version of MY 20mm/2.8 AF'D's focusing song...of course, your lens has been run through Auto-Tune, so it's perfectly on pitch with mine...but the styling of mine is more polished.

Is it me or does it sound a bit rougher pointed down?

I've owned three copies of the 20mm. One like new, one EX, and one beater. All with varying degrees of friction noise.

But, the friction noise I remember was from the focus assembly being overly loose. Your copy seems like there might be a small bind.

Yeah, its sharpness never let me down!

Yes, it sounds a bit rougher pointed down. Anyway, what do you mean by a "small bind"?

all my AF-D sounds like that. screw driven autofocus isn't really pleasant but the lenses are amazing nonetheless but i will agree with the previous statement that when pointed downwards it does sound a bit rough...it shouldn't sound differently (at least none of mine do)...

That's what bothering me, it sounds differently when pointed downwards. Anyway, it is still working great up to this date.
