子,据说gapless play 接近完成了,当然PSA 跳票了也不要奇怪. PSA 自己说因为bridge 是有256mb buffer 来播
放,gapless play 实现比较麻烦.
cue 是不支持的.CEO 自己说根本不知道cue sheet 是啥. |

据说这是sony第一次应用gapless microlens，只用在A7r上。
以前同款sensor，sony dxomark得分总比nikokn低一点儿，估计gapless是因素之一 |

掂。再借问一声，支持cue文件不？ |

主要看上了有gapless playback的能力
用来听音乐推bs41+subwoofer不算太差吧 |

发帖数: 587 | 5 估计有以下几个特征(因为技术在7D,550D上都达到了):
1.高清摄像:至少达到550D的Video,应该各种功能都有了
2.对焦:7D的对焦
3.感光芯片:估计是一个新的全幅芯片,用了microlense+gapless
所以估计是个十全十美的机器了 |

flash control估计也没戏
30MP是要上的，microlens一直就有，gapless应该会用 |

* Higher resolution 18MP CMOS with gapless micro lenses
* ISO 6400 no longer in 'expanded' range (12,800 max remains the same)
* Redesigned buttons and new movie/live view button
* Customizable auto ISO ranges
* Improved 63 zone metering (iFCL)
* 3:2 format screen with more pixels
* Improved movie functionality
* Slightly higher burst shooting rate (though buffer holds fewer shots)
* HDMI control (CEC)
* SDHX Compatible |

发帖数: 587 | 8 再说几句,7D芯片的gapless microlense以及高像素,很可能是带来下一次革新的前奏.
只是现在各方面还跟不上.所以7D可能就是一个超前于它的时代的机器.但凡超前于时代
的事物,往往都是杯具... |

发帖数: 41892 | 9 从D300跟D7000一比能看出来
51AF缩水，可以放到D9000
全金属机身缩水，
连拍缩水，才6fps，还能提高至少到10fps
再用上gapless microlens，这个D7k没有吧
还有啥D300比D7k强的？ |

发帖数: 41892 | 10 这个设计进光量应该少了。
但是如果本来就没有gapless microlens之类的话，本来有些光就是要浪费掉的 |

发帖数: 33224 | 11 Combining both high-resolution performance and a wide
ISO sensitivity range has finally become a reality. Nikon
engineers have developed intelligent new methods to
manipulate light transmission to the sensor’s photodiodes:
from the optical low-pass filter and on-chip gapless micro
lenses to the image sensor’s internal design, every measure
has been taken to maximize and improve light transmission
in order to deliver crisp, brilliant images with significantly
less noise. All this is possible unde... 阅读全帖 |

发帖数: 396 | 22 这要看像素大小。现在sensor都用gapless microlens， 500nm 工艺对全副per area
performance基本没影响。对APS-C有些影响，对1英寸sensor 500nm就该out了。 |

发帖数: 396 | 23 全副bsi就是个hype。越大的pixel bsi效果越弱。手机sensor bsi提高很大，因为
transistor占pixel面积太大。比一下中灰信噪比就知道全副bsi sensor信噪比增加很
小。特别是现在的全副sensor大多用gapless microlens，bsi的意义不大。Canon落后的
是动态范围，不是中灰信噪比。 |

Of interest is an analysis of Raw noise vs the a7R II – we took a look at
Raw files at ISO 25.6k files of the same scene run through dcraw. They
indicate only a slight advantage (possibly within the margin of our error)
to the a9 compared to the a7R II when viewed at common output size (SNR of 3
.4 vs 3.7 between the a7R II and a9, respectively, for a similar patch).
Physics predicts this: for two sensors of similar technology, it’s sensor
size that matters (especially with gapless mi... 阅读全帖 |

发帖数: 8 | 26 not exactly. what he meant was that, if the symmetry in the original Lagrang
ian is exact, then the symmetry breaking state has gapless excitations with
exactly zero energy gap.
However, if the symmetry in the original Lagrangian is not exact, but broken
by a very small term, then rigorously speaking there is only one phase, but
the crossover is very steep, therefore you can still sort of talk about "sy
mmetry breaking". In this case, the Goldstone mode will aquire a very small
mass gap.
