42MP比一般20MP也就2倍，算线性resolution也就根号2，才1.4。那个35mm镜头最多也
就相当于50mm镜头装在6D上。当然前提还是你镜头能resolve那么多细节喂饱sensor的
情况下，这个50mm是上限。我听说那个35mm 2.8轻巧很锐，但是能喂饱42mp我还只听说
过otus这种。
当然，我还是可以理解每个人都喜欢自己的相机。尤其是买了这么好的相机。不过也用
太夸大了。 |

and wedding
感觉canon研发搞了太多的 cinema eos，市场也不是很好，不知道是什么策略。
干脆把那个42mp的sensor买过来算了 |

A7rii 给我的感觉很像d800升级到d810，responsive了很多，没什么lag，操作比较
smooth，对焦快了不少。高感有一点提高不过还没有仔细比较，low iso 和a7r 差不多
。
fe35 1.4在a7rii上略大，front heavy， 55 1.8应该好很多。随便拍了一些，除了有
些distortion（拍建筑会看到），FE 35 还是很不错的。锐但bokeh transition 非常
自然，色彩我觉的有些浓郁，和 sigma art 的超锐利，清新偏淡不一样的风格。最近
长焦用多了，用35mm不是很有感觉，总觉的太宽了。好处是42mp可以使劲crop, 快赶上
微距了。
还有几张 Nikon d7200 and 300MM PF with 1.4x 拍的花草，希望nikon to FE AF
adapter 早点出来，可以转接试试。 |

It’s highly likely the camera will feature a Sony FF sensor although it’s
not clear if it will use the 36MP or the new 42MP sensor from the A7rII. A
very interesting info is that the camera will feature a High Resolution
shooting mode according to the reliable source Thistanaka." |

发帖数: 3190 | 15 "Winner: Sony Alpha 7R II
The Sony's combination of image quality, video capability and autofocus
performance come together to make it our camera of the year. The camera's
sheer capability: a 42MP sensor that performs well in high contrast or low
light situations, built-in image stabilization, 4K video with internal
recording, is hugely impressive. But add to this the ability to sensibly use
other brands' lenses and the a7R II becomes a significant camera far beyond
the market for this particula... 阅读全帖 |

II. They have tested RAW dynamic range performance as well as ISO to give
you an idea just how good the new 20.2mp Canon sensor is.
Dyanmic Range
The Canon EOS-1D X Mark II shows very similar amounts of noise to the
excellent sensor in the Sony a7R II up until a 3EV push, with the Canon
dropping behind after a 4EV push. It’s a similar story against the likes of
the Nikon D750 or D810. This means that the darker shadows in... 阅读全帖 |

到20MP这些噪声基本就不明显了。更何况如今软件后期降噪已经非常厉害。 |

不是内存的问题。主要看cpu性能。somehow 24mp到42mp慢了不少。不光是我，网上不
少人高配电脑也有抱怨的。LR主要用单核cpu，近几年cpu速度也没有涨太多。 |

发帖数: 774 | 20 爱因斯坦还是爱迪生的错误。
我买了一个sony a7r2，又买了一个清仓大降价佳能70d。
我的想法sony拍风景，70d打鸟
但是有人说为什么不用sony打鸟，虽然crop sensor有1.6 factor，600mm就是960mm，
但是索尼42mp，70d只有20mp，所以还是索尼a7r2打鸟好。
但是我想问问，sony是不是只有tamron 150-600 + la-ea4，才能全程autofocus，
sigma+ mbiv只能autofocus到250mm？ sony加了la-ea4是不是对焦比较慢。
我是否犯了大狗走大洞小狗走小洞错误。现在还没开盒子，要不要把70d退掉呢。
有没有大师说说 |
