Hi, I have a Canon lens 28-105mm f/3.5-4.5 ultrasonic. When AF mode I hold the shuttle button to forces, the lens mechanism making noise. Ultrasonic lens should be quiet right?
Got fungus on top of lens, but not really serious.
Please advise if me, AF mechanism got problem.
If anyone willing to take a look would be better.
