各位師兄，小弟買了2個月，支鏡在35mm焦段走焦，問過CS佢地話Cal鏡不需拆開，將鏡頭安落個座度用電腦調校，是嗎？請各位師兄解答，謝謝。

連cs 都唔信,咁你用canon 黎做咩呢

Cal 鏡即調較,與調較手錶和磅同理,為何要拆開?

I think they don't need to dismantle the cover at all......
from my experience, I take a sigma lens to cs for cal. That guy enter the lab for only 3 minutes and come out and tried to shoot on the sceney for cal. And then he ask me to try, I said the infinity seems not so good and he went back to lab for another 3 min
so I think in this 3 min, he can't open my lens that fast. They may use some contact to adjust the value.
