同感。。。虽然我是苹果粉丝。
但是看到sony的z1有20mp。
苹果的相机是不是那么不给力
你有看发布会是如何介绍新的 iSight 手机的吗？
你去看一看，noise 会更低，颜色更漂亮
不是 MEga pixel 越高越好，而是 Pixel Size 越大越好
其他厂商的pixel size才 1.0-1.2 micro
苹果的是 1.5 micro
Bigger Pixel = Better Picture
Pixel Size
Higher megapixels increase the resolution of the images but equally imporatnt is the quality of the individual pixels. At the moment quality pixel equal bigger pixel size but this may change as new technology and new material for sensor chips are discovered in the future.
A bigger pixel size result in better sensitivity to light and produces stronger image signal. Stronger image signal improve image quality, better colour fidelity and less noise due to improvement in signal to noise ratio.
Increasing megapixels count on a given size sensor chip can havenegative impact on image quality. Pushing more pixels on a given sensor chip results in smaller individual pixel size. This means lower quality sensor resulting toincreased noise level, lower dynamic range, reduced colour fidelity and finally poor image quality.
