noise from the XF 16mm f/1.4

[tokhee]

hello - i have an XT-2 and when i use the 16mm f/1.4 in manual focus mode. i switch the dial on the camera to M and when i rotate the focus ring, there's a slight resistance where it feels/sounds like the auto focus motor(?) is being turned. can anyone who's got this lens see if it does the same thing? thanks.

Think focus by wire!

thanks for the respond Mike G. but the kit lens, 18-55 doesn't do that when i focus manually. is it only with the prime lenses?

after doing some research it seems like the grinding noise i get when focusing manually is the norm. it's unfortunate because i purchased the XT-2 to shoot mostly video (4K) and the Rode VideoPro mic picks up the noise, making the footage unusable.

I could be wrong, but I'm pretty sure the quiet lenses are the ones with linear focus motors (they use magnets instead of a motor). So far it consists of the zooms and the 90mm IIRC. All the primes use traditional motors - they all vary in noise/volume, but the 16mm is one of the quieter ones. Out of the lenses I own, the 16mm and 56mm are the quietest, and the 18, 23, and 35 are all louder.
