Image capture device and converter lens assembly thereof
First Claim
1. A converter lens assembly comprising a first lens, a second lens, a third lens, a fourth lens and a fifth lens, all of which are arranged in sequence from an object side to an image side along an optical axis, wherein:
- the first lens is with positive refractive power;
the fourth lens is with positive refractive power; and
the converter lens assembly satisfies;
1<
f1/f2|<
2 and 1<
f345/f2|<
2 wherein f1 is an effective focal length of the first lens, f2 is an effective focal length of the second lens, and f345 is an effective focal length of the combination of the third lens, the fourth lens and the fifth lens.

Abstract
An image capture device and a converter lens assembly thereof are provided. The image capture device includes a mobile phone and the converter lens assembly wherein the converter lens assembly is connected to the mobile phone. The converter lens assembly includes a first lens, a second lens, a third lens, a fourth lens and a fifth lens, all of which are arranged in sequence from an object side to an image side along an optical axis. The first lens is with positive refractive power. The fourth lens is with positive refractive power. The converter lens assembly satisfies the condition: 1<|f1/f2|<2 and/or the condition: 1<|f345/f2|<2, wherein f1 is the effective focal length of the first lens, f2 is the effective focal length of the second lens, f345 is the effective focal length of the combination of the third lens, the fourth lens and the fifth lens.
