The lens has a 3x zoom range, covering a native 5-15mm angle, which translates into a 24-70mm field of view in terms of traditional 35mm photography when used with the Q7 thanks to its 1/1.7-inch image sensor. If you use it with the older Q or Q10 the field of view narrows to 27-83mm. The maximum aperture is f/2.8 at its widest setting, which dwindles to f/4.5 as you zoom all the way in, and it uses 40.5mm filters. The lens itself is 1.9 by 1.9 inches (HD) in size and weighs about 3.4 ounces. It can focus on objects as close as 11.8 inches at any focal range. The lens has a built-in neutral density filter, so you can shoot at lower shutter speeds in very bright light, and its leaf shutter can sync with an external flash at speeds of up to 1/2,000-second.
