我剛入咗43AM，
但發覺如果用AUTO＋＠A77，
對焦距離少過1．2 M時，
個SCREEN就閃話叫用“WIDE”，
如果我唔拉下塊 WIDE 光，
個閃就好噪，跟著個ZOOM RING 轉動時有聲。
請問各高手指敎下，
係唔係正常現象呢？
58AM 又有冇類似問題？
我係新手用電子SLR。
唔該。

問咗SONY, ,原本 43AM 同 58AM 都有內置MOTOR, 所以同步A77有機會有聲.

HVL - F43AM is auto flash with auto zoom function, which will zoom in and out when you do the same for your lens. It's normal and can give you the right flash power.

Yes, now I got it.
It seems like I need to pick up more knowledge of DSLR nowadays .
Somehow I feel the technology is too advance for me
Thanks, Clarence Ching.
