    • An optical image capturing system, from an object side to an image side, comprises a first, second, third, fourth, fifth, and sixth lens elements. The first lens element has refractive power, and an object-side surface of the first lens element is aspheric. The second through fifth lens elements have refractive power and both of an object-side surface and an image-side surface of the fifth lens elements are aspheric. The sixth lens with negative refractive power may have a concave object-side surface. The image-side surface and the object-side surface of the sixth lens element are aspheric and at least one of the two surfaces has inflection points. The second through fifth lens elements have refractive power. When specific conditions are satisfied, the optical image capturing system can have a large aperture value and a lower height of the optical image capturing system, and it can also improve imaging quality.
    • 从物体侧到像侧的光学图像拍摄系统包括第一,第二,第三,第四,第五和第六透镜元件。 第一透镜元件具有屈光力,并且第一透镜元件的物体侧表面是非球面的。 第二至第五透镜元件具有屈光力,并且第五透镜元件的物体侧表面和图像侧表面都是非球面的。 具有负屈光力的第六透镜可以具有凹入的物体侧表面。 第六透镜元件的像侧表面和物体侧表面是非球面的,并且两个表面中的至少一个具有拐点。 第二至第五透镜元件具有屈光力。 当满足特定条件时,光学图像捕获系统可以具有大的光圈值和较低的光学图像捕获系统的高度,并且还可以提高成像质量。
