高像素 DC 降临：1610 万像 Sony W570 速测[44P]

从 2011 年 CES 中各大厂商所发表的新机之中，可见新一轮的「像素竞赛」正式展开，不少 DC 都将像素进一步推至更高的 1600 万。而作為最大的感光元件开发厂之一，Sony 当然亦不例外，率先登场的便有今次送测的 Cyber-shot W570，相机不只拥有 1610 万的高像素，亦设有一扫全景及 HD 高清拍片等功能，以轻便 DC 来说，规格与功能都有一定看头。

[b]1610 万解像、25mm 广角、一扫全景、HD 高清拍片：Sony Cyber-shot W570[/b]
作為一部轻便 DC，用家首要考虑当然是相机是否轻巧，而 W570 便首先满足大家这方面的要求。W570 在配备一支 5 倍变焦镜头之下，机身竟然只厚 19.1mm，而相比起 iPhone 4 一类智能手机（iPhone 4 重量為 137g），相机 116g 的重量亦要更為轻巧，绝对可成為一部称职的随身机。沿用 Cyber-shot 系列的风格，W570 同样採用简约的外观设计，相机并配以金属机身面版，令平价感一扫而空。
為了追求更高的解像，今次 W570 特别配备了一片全新的 1/2.3 吋 Super HAD CCD， 理论上足以应付更大尺寸的输出（以 150 dpi 计算，可印出 30 x 23 吋的相片）。利用较低感光拍摄，相机可谓充分发挥其画质上的优势，以一张拍摄糖果的相片為例，相片的色彩便不单层次丰富，解像亦有一定惊喜。要「尽用」相机的 1610 万解像，镜头亦是当中的关键。而一支 Carl Zeiss Vario-Tessa 25-125mm 镜头於解像上便满足了这方面的要求，镜头不只於中央提供锐利的成像，边缘解像亦未有明显的下降，估计是透过机身内置修正，镜头广角及远摄两端并未有发现任何变形，例如用於拍摄建筑等线条分明的题材，便不会出现一般广角拍摄的桶状变形。
虽然定位入门，不过 W570 於功能上亦未「将货就价」，除了支援 720p 高清拍片，相机亦内置有 Sweep Panorama 一扫全景功能。W570 的一扫全景除了过去的标準及广角模式，亦新增了水底全景模式（当然需配合防水机壳使用），用家只需根据设定好的拍摄方向（上、下、左、右）Pan 镜拍摄，相机即会高速连拍多张相片，自动接驳為一张全景相片。而要拍出理想的全景效果，除了 Pan 镜要够稳定，另外要注意的是拍摄期间相机的曝光亦会被锁定，要避免相片部份位置出现大黑大白，拍摄前，不妨先留意一下现场的光差。
