I am a new comer and cannot decide which one to buy. I note that the resolution of C5050Z is only 72 dpi but the Coolpix5000 is over 300 dpi. Does it mean that Coolpix5000 is much better? I also don't understand when both DCs are 5M Pixels, why there is still resolution different?

Please help.

[hi-hi-]

me too......
質素如何??
有何優點及缺點??

[小春]

ha~~兩部都好難取捨呀
唔知你地有冇睇今期digi數碼双周呀
重點比試兩部機的功能~~

上面提及的dpi 問題, 完全是概念上的錯誤, 72dpi 是在電腦上看時的解像, 大家都是 5MP, 2560 x 1920, 在電腦看全都是72dpi, 至於300dpi, 是一個output 相片時的最佳數值 (dpi = dot per inch), 越接近300dpi, 相片質數越好, 8R 相片的高度為 8吋, 1920 / 8 = 240dpi, 所以 5MP output 8R 相是很好質數, 當超過 300dpi 時, 根本肉眼觀看已無大分別.............

兩部機性能相近, 當然亦互有長短, 個人來說傾向CP5000, 因為C5050 在影高反差環境時, 紫邊真的很勁, 即使影室內, 如有強光石英燈, 一樣會冇問題...
但如能避開這些環境的話, C5050 又真的很出色, 因其色彩還原比CP5000 做得更好..............

其餘像 手感, 操作速度, 按制是否方便就手又易用等等.......真的要親身試機才可以............

而買得呢d 高級機, 相信亦要考慮各種配件如 Flash, Wide / Tele Lens 方面, 是否足夠....

Thank you JackNgai. Very useful information.
Then some reviews posted by others are wrong because they said 72dpi is bad for C5050Z. I also read the DC magazine comparing the two DCs but found that they are very general and cannot help me to make a decision.

I like coolpix 5000 too. However, I have one more question. Is the 5000 very difficult in focusing correctly at night?

Thanks for your reply and Happy New Year!

夜間對焦不難, 在k房都可影到, 我在自己房間, 全黑的情況下, 都得, (AF綠燈閃)

[jackngai]

上面我打錯字 應該係 " 一樣會有問題" 先真............

ronald兄, 唔係要綠燈長亮先叫對焦正確咩??

不過, wl 你唔需要太過在意呢個問題, 因為除左Canon 有數款型號有對焦燈, 可以在短距離內, 能在無光下對焦外..............其餘DC 全部都係黑夜對焦困難 (DSLR 除外)...........

C700 / 720 / 730 都一樣暗位對焦困難, C5050 一樣冇對焦燈所以都未必會有驚喜................

除了影燈飾外, 我們都會準備一支強力小電筒, 射住主體令其反光, 咁就實對到啦.....

點解唔選g3呢?
c5050真的很型,黑色,大光圈,
我現在在g3同c5050兩部機中煩惱中...

[jackngai]

級數唔同.............G3 係 4mp, 應該同cp4500 / c4040 比較.......

[louisho]

5050有暗紅色對焦燈，好黑都對到焦。

[onechan]

但係g3既功能都好過呢兩部喎
c5000得2.8光圈><
c5050有1.8
g3就有2.0
\其實邊部好?

[jackngai]

louisho 兄資料正確, 我看錯了, c5050 是有對焦燈的...


onechan,
F2.8, 其實已經唔細架啦, F1.8, F2.0 係大, 在一些光源稍差情況下, 能夠用高速一點的快門, 這是好處, 但唔代表一定贏...........仲有好多因數, 最好就親身試機先決定...............不過 c5050 的色散問題, 下下要就住唔可以向光源影, 我覺得綁手綁腳咁..........所以我唔揀.............而CP5000 性能好夠用, 又係 5mp ,曬相執相都比G3 多彈性...........

千祈唔好話 像素唔重要, 係的話, 你不如買S602z , 因為無論光圈的最大最小範圍 (F2.8-3.1), 光圈級數 (13段), 快門range (1/10000sec - 15sec), 各ISO值的平均質數, 6x zoom..................以上三部機全部都輸晒.............而呢d 全部都係性能中好重要o既部份.........但點解唔係個個要s602丫??? Pixel 問題囉, 好多人唔接受 SuperCCD 的 6MP 嘛.............

4mp 機, 我個人覺得半天吊, 要曬 5R, 3MP 機都得, (1536 / 5 = 307dpi), 但8R 呢?? 5MP 都係剛剛好 (1920 / 8 =240dpi), 再細d, 已經唔夠清.......

[hkhei]

我想提一提o既係，其實cp 5000都有色散o既問題...
而且都算嚴重(不過及不上5050)
不過cp5000最wide係28mm..比5050的35mm實用...
而且個lcd可以扭...

[jackngai]

講真就三部機都有, 但c5050 叫做勁得好明顯囉....

[patwong]

C5050Z 色散 problem really quite serious.
CP5000 f/2.8 is enough. with its 28mm wide angle. ^O^ I also like its rotational LCD. Not many camera have such function.
G3 although have f/2.0 with rotational LCD and 4x zoom, it just have 4MP, still not enough I think.
S602Z really function and quality very good. But its pixel just 3MP .... (I do like this machine most, except its 3MP CCD.... if having 6MP CCD can interpolate to 12MP, really a perfect machine)
