400应该比900S在同样放大倍数(如五十倍)下画质更好。虽然两者SENSOR都是1/2.3寸大,但因为前者ISO最低可到80,噪点会比900S的100更少。另外400的快门最长可到30秒,拍无光照夜景时效果远好于900S可怜的15秒。这也是为何我选H400(最低ISO及最长快门同HX400,但光变倍数多出13,价格也便宜了六七百)而非900S的两大原因。 Today was good. Today was fun. Tomorrow is another one.
当然,400的像素也高出900S好几百万,同等情形下画质也会比后者更好,加上价格比后者低了约一千大洋,这也是我选H400而非900S的另两原因。所以,除非你需要83倍光变胜过上述各因素,否则HX400或H400会更适合你。 Today was good. Today was fun. Tomorrow is another one.
