This super-telephoto lens with a high zoom ratio covers a wide range of nearly 4.3x yet only 4.5". A steady and firm zooming mechanism with superb endurance reduces instability of the cam barrels, resulting in high picture quality throughout the range. The lens is ideal for capturing truly candid shots at 70mm or taking close-up photos of wild birds or animals while remaining at a non-intrusive distance at the 300mm super-telephoto end. A minimum focusing distance of 3' and a maximum magnification of 1:2 are powerful enough for good tele-macro photography of flowers and insects.
Macro Effect of 1:2 in Telephoto Zoom Range
Flipping a macro switch in the focal length range of 300mm allows entry into the macro range, for photography as close as 3' from the subject. In the macro range, one can take advantage of the telephoto effect and a maximum magnification ratio up to 1:2. n
