p.1 #1 · p.1 #1 · Noisy AF for Canon EF 70-200mm f/4L IS?


Just bought this used off the forum and the AF is snappy but a little noisy. Is that normal? The noise doesn't seem like it's grinding or anything crazy like that, more like the AF is moving. Just wondering if it should be silent.

Also, it's crazy how light this lens is compared to the f2.8 IS version. Like night and day. Glad to shed some weight on my travel tele now!

Your description sounds about right, to me. I have the 70-200/4L IS and 70-200/2.8L IS II, and the f/4 makes a brief, "skritz" sound when it kicks in.

Yes it's quite noisy compared to any other L lenses. I think it's the IS that was making most of all the noises. So I think it's normal. Mine is quite audible immediately after the AF button is pressed.

Thanks for the replies!!

My back and legs are gonna feel much better after bringing this lens on vacation, as opposed to the f2.8 IS

IS did make the "skritz" noise when you half press the shutter, however no noise if you turn the IS off.

Relatively speaking it's a bit on the noisy side compared to the newer IS systems in the current lenses which are pretty much close to silent.

This is normal, the 70-200 f/4 IS stabilizer hum is louder than any of Canon lenses I have used.
