发明名称 ZOOM LENS AND PHOTOGRAPHING DEVICE HAVING THE SAME
摘要 PURPOSE: A zoom lens and a photographing device having thereof are provided to offer a compact and low-priced zoom lens having high magnification. CONSTITUTION: A zoom lens(111) comprises a first lens group(G1), a second lens group(G2), and a third lens group(G3) which are sequentially arranged in a direction from an object side to an image side. The first lens group has a negative refractive power. The second lens group has a positive refractive power. The third lens group has a positive refractive power. During zooming from a wide angle position to a telephoto position, the interval between the first lens group and the second lens group decreases, and the interval between the second lens group and the third lens group increases. The first lens group comprises a first and a second lens which is a negative lens made of plastic, and a third positive lens which is a positive lens made of plastic. The second lens group comprises a fourth lens, a fifth lens, and a sixth lens made of plastic. The third lens group performs focusing by performing image plane movement and focus location correction during zooming. [Reference numerals] (AA) Wide angle position; (BB) Middle position; (CC) Telephoto position
