The F2.8-3.5 brightness of this wide zoom lens is really attractive. This high-performance lens covers the zoom range of 22-44mm on a 35mm camera, and the closest focusing distance is 28cm in the entire zoom area. It can create a desirable tension in your photographs by exaggerated perspective effect. Two glass aspherical lens elements create a high image quality with high-resolution and excellent contrast.
