Thanks for the replies, everyone; it was the aperture blades making noises.. is it normal with your experiences? I have the 35mm (Thank you Randy) and the 18-55 zoom... Both makes the same noises when focusing, while the zoom is a bit quieter...

Will you consider this to be a defective or just normal for the X range lenses?



Hi James,

This is quite normal since all lenses make noises when the aperture blades stop down. They close down to your selected aperture for DOF preview during focusing so it's quite noticeable.

Have a look at the size of the diaphragm between the 35mm and the zoom and take note of the amount of travel the blades have between the two - this will explain the difference in noise.
