Actually my 27mm isn't too bad by comparison.Outside of the Fujicrons, most Fuji glass is relatively noisy. Some lenses more than others - 18mm, 27mm, 35mm being the worst cultprits.
Especially when comparing to my Sony FE glass (28mm/35mm/55mm/85mm), which is all near silent. Have to put the lens right up to my ear to hear anything.
Debating what's next, maybe the 50mm. I got the 18mm and 27mm because I like the focal length. I know the 23mm and 35mm are newer with faster and quieter AF, I'm not just sure they're for me.This brings me back to my first Nikon 85mm 1.8. It was a beater non-d. Sounded like a rattle snake. An angry one too.
I have the 18 and 35 and am used to the noise.
On a side note the 23 F2 is pretty silent and a little wider than 23. Could be a nice alternative.
