谢谢老Joe, 可是很奇怪Sony 对镜头zoom是分开描述的:
# Digital Zoom : 160x
# Extended Zoom : 17x
# Filter Diameter : 30mm
# Focal Distance : f = 2.9mm - 34.8mm
# Lens Stabilization : Optical SteadyShot™ Image stabilization w/ Active mode (Wide to Tele)
# Lens Type : G Lens™
# Minimum Focus Distance : Approx. 1cm (Wide), Approx. 80cm (Tele), Approx. 25cm (Tele Macro)
# Optical Zoom : 12x
类似的Canon 对镜头zoom是这样描述的:
Zoom Ratio: 28x Advanced/20x Optical/400x Digital
Focal Length: f-3.0 - 60mm
35 mm Equivalent:
Optical Zoom: 41.2 -824mm (Standard IS/OFF), 49-980mm (Dymanic IS ON)
Advanced Zoom: 41.2 - 1154mm (Standard IS/OFF), 49 - 1176mm (Dynamic IS)
Filter Diameter: 34mm
便宜的后者Canon（$269）镜头口径还要大一些.
