سلام به دوستان و اساتید عزیز
این قسمت از کتاب David Busch’s Nikon D7000 Guide to Digital SLR Photography در مورد لنز AF اینگونه نوشته :
WARNING
Do not use a lens marked AF (rather than AF-S) when the focus mode switch on the lens
is set to M and the switch on the camera is set to AF. As you’ll learn in Chapter 11, non-
AF-S lenses do not have a built-in focus motor, and are focused by a motor in the camera
body instead. When you set up the lens/camera in this conflicting configuration, it’s possible
the camera’s internal motor may try to focus the lens (which has been set for manual
focus only) and, with some lenses, damage can occur to the camera’s focus motor. With
AF-S lenses, the lens and body switches should agree, but no damage should occur if you
have a mismatch; if either switch is set to M, then manual focus is what you will get.
دوستان و اساتید محترم ، لطفا کمی توضیح بدن ، آیا واقعا میتونه به موتور فکوس دوربین صدمه بزنه ؟
