我諗都好睇師兄究竟你有幾多budget，但為5N同7既價錢都差好遠，5N就淨機就唔駛五千，7 ...

多謝回覆, 咁睇黎都係敗左NEX5N先算啦...

買咗記住啲相放上嚟參吓喎

其實我睇D FORUM講NEX5N的NOISE REDUCTION已經處理得好好. 有D人重話希望NEX7可以用返NEX5N的CMOS添... 不過我諗既然佢係NEX7出得24M o既, 冇奶油會屎過NEX5N卦.... 始終個價差咁遠...

It depends on your need:
If you need high resolution, then wait for Nex7;
If you need better high  ...

都係BUDGET啦. 玩具嘅嘢, 平有平玩, 4-5X 二手又有,,
玩10万8万機嘅又大有人在,,但佢哋同樣都咁ENJOY,,
唔太喪志OK啦...

100% SURE, the noise level of NEX7 is worse than NEX5N.

Technically, S/N is the measurement unit of noise, where S=signal, N=noise.
If the signal is strong then mean a better S/N
If the area per each pixel is larger, then more photons can be capture, thus higher signal strength.

The sensor size of NEX5 and NEX7 is the same, then the 24MP NEX7 mean a smaller area per pixel thus weaker signal strength....

May be too technical.
In a simple way, higher pixel density mean worse ISO performance.

About noise reduction (NR), it is an software algorithm used to guess which pixel is noise and which pixel is normal pics data.
NR usually lead to lost of pics detail, worse dynamical range and worse color depth.
So, the perfect case is: no need to use NR
