2. 邊部sony機高ISO表現最好？

[FaithYeung]

1. Don't Know
2. For Sony alpha mount A580. For Sony NEX, I am not sure. Maybe NEX-6?

[小小生]

1.唔知
2.NEX-6和5R未試過,試過的最好係NEX-5N
而NEX-5N好過A57,A57好過A580

According to Dxomark, Sony 16MP sensor gets the highest score of low light performance. Of those, Pentax K-5 is the best:

http://www.dxomark.com/index.php/Publications/DxOMark-Reviews/DxOMark-review-for-the-Pentax-K5

Quote "The overall score of the K5 puts it in the lead with 82 points — more than 9 points better than the D90 or the Alpha 55, and 16 points ahead of the Canon 7D or 60D. The K5 is literally the best APS-C performer for each segment, even in low ISO."

Among Sony, because A580, Nex 5N/5R/6 are using the same generation 16MP sensor and without translucent mirror, so their noise level should be very close (just minor difference due to software/processor tweak

又谷像素,又半透明減光鏡,noise控制差係意料之內.

Fuji X > Nex 5n / Samsung NX > Nex 7 > Sigma
