看了 1D4 要過$40k 定價，實在嚇呆了……
再看7D定價$13~14k 實在低用極了……

當38點十字對焦遇上19點十字對焦時，究竟贏到幾多呢？就像是千五萬像同千八像吧！

只是有感而發！！隨便發表

我用緊7D，單從spec睇真係吸引力不足，不過當然可能係我個人無試過真正好O野先至有咁嘅感覺。至於10幾萬ISO嘛...大家都係行Dual digit IV，從7D的減雜訊能力來看，係咪只係數字遊戲，其實係完全唔會用到的？

mickey兄，你用你7D ISO 25600 -2EV 影 然後於 DPP 推高兩級，可能就係咁上下的表現吧！

I can say keeper rate the same in most of the conditions

First, 1D series is using APS-H censor which is approx. 20% bigger than APS-C 7D censor. Therefore, PQ is sure better if you measure at the same resolution. Noise will appear more in APS-C sensor than in APS-H at high ISO situation.
I used to have 40D and now I am using 1D mark III for sporting shooting. Both 10 Mega Pixals. When I compare the similar photo which is shooted in RAW at ISO 800, the Diffferent is quite significant.
For the cross type sensor comparison, more cross type sensor sure did better in low light condition When you are using AI Servo mode for fast moving object and you are panning on them, you might get a higher possibility to capture a right focus pic.

This is my experience sharing. Let's discuss further !

The cmos of 1dm4 is larger than 7d 20% and the pixel is lower than 7d.
I can say the noise control must better than 7d.

起初以為 aps-c 同 FF noise 分別就好大，aps-同aps-h 分別無咁明顯，照咁睇， aps-c 18MP noise 會勁過 aps-h 16MP 頗多下！！

各師兄，請多分下對焦力添呀！

[seanlam1234]

對焦力除左點數多, 仲要夠快夠準
差少少就係少少, 唔係點做到一秒十張
反光板係咁升升趺趺, 對焦慢少少都唔得

1d除左對焦力, 仲有更大的電池
一體化的直倒, 更多的自選功能
更強的防塵防滴, 更好的組裝強度...etc

小小小小加起黎就係多ga la

反過黎講, 可能係
玩家7D, 用家1D
要跑記招, 影運動, 打雀仔的人
1D還是有需要的

[seanlam1234]

不過1D mk4還真貴...

差唔多可以買到5d mk2 加大三元
又或者7d 加 24L 35L 50L ...

[Marksman01]

Except the money different, in gear wise, 1D4 is much better than 7D, no need to think too much la.

[louis277]

1D price range is always like this....like a symbolic of status! :P

[wesleyyau]

唔好講1D4... 自己睇o下1D3 同7D 有咩分別... ISO3200 100%crop NR(Standard)...

1D3


7D


因為係用小畫家crop 相... 所以有degrade... 可以去
http://www.imaging-resource.com/IMCOMP/COMPS01.HTM
自己比較...

[wesleyyau]

送多張50D ISO 3200... 睇o下50D detail 多定係7D 多...

就會發現谷resolution o既結果... 有d 人唔會聞相... 又或者覺得pixel to pixel 比較唔公平... 其實呢樣o野o係40Dvs50D 已經係咁...

[Marksman01]

Personally I like to compare them in the same size because I always print out actual photos with size A4 to A3+.

[h0001244]

嘩！！
連D花紋都無埋，死火！
