E文的意思跟你的中文描述相差很大，西吹在抹黑对手方面，也是不遗余力啊，S1R的自动对焦，总体评价还是很高的，我印象中完全不低于当年给A9的评价，DPR当年给A9的自动对焦，有明显的讽刺意味，西吹要不自己去翻翻看？

估计卖不到1000台

对RAW来说，每个像素点就一个14bit的色，是马赛克结构RGGB中的一个，

哈哈，DPR的总结。我靠！动态范围，信噪比，自动对焦和竞品比均有明显差距。即便jpg输出上，其降噪算法也远不如此领域的绝对领先者Sony。唯一在画质上可吹一下的就是1.8亿合成摇摇乐。哈哈，看了这总结都笑死我了。

后面又说了：自动对焦性能的运动对焦根本就是灾难，视频对焦性能没啥可用度。

反正dpr的意思，这玩意儿作为一部相机来说，对焦，画质最重要的性能基本和渣没两样。后面唯一大片幅吹的只能是三防个坚固度了！看完这个总结，基本这就是一部干啥啥都不行的板砖，适合装bi，健身，锻炼腕力。顺便防身！

For starters, there's the image quality. The 47MP sensor in the S1R isn't class-leading in ultra high ISO performance, dynamic range or resolution, but it is a good sensor that puts out pleasing files. Panasonic also deserves praise for putting out some truly excellent (if large and expensive) lenses at launch, so you can get the full benefit of those 47MP using native lenses right away. The S1R's JPEG engine is up there with the best, trading just slightly clunkier noise reduction compared to Sony (the class leader in this respect) for great out-of-camera color rendering. And for those that need more resolution, the 187MP high-res mode is impressive, with some of the best motion correction on moving objects that you'll see this side of a modern smartphone (many modern phones stack over a dozen images with zero shutter lag).

This camera is meant to be a solid, reliable workhorse, and at that, it succeeds
And then there's the feel of the thing. In the hand, the S1R feels solid, reminiscent of pro-level sports DSLRs like Nikon's D5 or Canon's EOS-1D X II. The grip is fantastic for medium-and-larger-sized hands, and the abundance of external controls means you shouldn't find yourself diving into the menus too often. The weight, though, does mean your wrist will tire from longer shooting sessions. The collection of autofocus controls is a particular strong point, clustering together autofocus modes, areas, a joystick and AF-On functionality for easy right-thumb access while shooting.

But despite those excellent controls, when it comes to autofocus, it's not all good news. Panasonic's Depth from Defocus system drives compatible lenses very, very quickly, and gives a pretty good hit rate, but the focus 'wobbling' and drop-off in viewfinder resolution will be off-putting to some users and doesn't inspire confidence. Couple that with a lackluster burst speed with autofocus, and action shooters that also crave billboard-ready resolution may need to look elsewhere. The AF system can also prove problematic for video shooters, but we'd expect those users to be more tempted by less expensive options anyway. Video on the S1R is good for a high-res camera, but you can save some money and get better video quality by shopping around a bit.

如果不考虑JPEG的压缩，对单个像素来说，JPEG是24bit，RAW是14bit，多出10bit，JPEG压缩后才会比RAW小，

当噪点很多时，JPEG的压缩率大大降低，JPEG比RAW大就很正常，

好不好看疗效

就像日本车 防撞指标高 实际碰撞没美国车好

S1的感光器99.99999%是SONY的IMX 410。
