Canon 1D MKIII vs. Nikon D3
Sports Autofocus Showdown

Therehas been a lot written about the autofocus performance of these twoclass leading cameras. But, as far as we know, no scientific tests havebeen conducted comparing them head to head in the toughest autofocustest around.

Canon 1D MKIII
First, a little history, the Canon 1D MKIII has been plagued withautofocus issues throughout its release. We reported extensively onthese issues hereacross 5 months last year. In case you missed the whole episode,basically, Canon produced some bodies with hardware defects. Weproposed as much on July 16, 2007.

"The data strongly suggest:
There are bad focusing Canon 1D MKIII bodies in circulation and there are good focusing Canon 1D MKIII bodies in circulation.

We just finished putting a newer 1D MKIII body through the rigors ofthe running test, and it performed as well as the 1D MKII. "

These defects were repaired by Canon at no charge. But only after muchhand wringing and testing by independent photographers and websites.Canon has extended the warranty for those cameras needing thesub-mirror repair. There are still reports from a few sourcessuggesting that the hardware repair was not sufficient. We have loadedup the latest firmware v1.2.3 on the prior "good" body that has been through all Canon sub-mirror repairs.

Canon 1D MKIII Results
300mm f/2.8 lens at f/2.8, AI Servo, Center Point Only
latest firmware v1.2.3, sub-mirror fix performed

We ran a number of test trials with this newly refreshed camera. Here are the results across 5 test trials.

Running Test Trial #1:
21 out of 59 Out of Focus (36% Out of focus)

Running Test Trial #2:
17 out of 70 Out of Focus (24% Out of Focus)

Running Test Trial #3:
19 out of 48 Out of Focus (40% Out of Focus)

Running Test Trial #4:
16 out of 55 Out of Focus (29% Out of Focus)

Running Test Trial #5:
12 out of 46 Out of Focus (26% Out of Focus)

Canon 1D MKIII Overall Average:
31% Out of Focus

Running Test Trial #3:
17 out of 40 Out of Focus (43% Out of Focus)

Running Test Trial #4:
24 out of 36 Out of Focus (67% Out of Focus)

21 out of 41 Out of Focus (51% Out of Focus)

(43% Out of Focus)


And the winner is...

Canon 1D MKIII with only 31% Out of Focus

Conclusion
Aswe mentioned earlier, there has been a lot of talk about the Autofocusweaknesses of the Canon 1D MKIII. A lot of this talk is quite frankly,undeserved. We have never been able to replicate the seeminglyimpeccable performance of the Canon 1D MKII as observed by otherparties.

I highly doubt many current gear purchasers are willing to go back intime to purchase what is now an ancient camera, in terms of overalldesign and features.

Hence our test of the current crop of viable options. The Canon isagain the clear winner in this category. We also did this same testwith one generation earlier firmware and the results were very similar.This earlier report was never published, because we just did not havethe time.

Does this mean that the Canon 1D MKIII is the clear choice for overall autofocus?

No.  It simply means that it performs better under this rigorous test. 

Firmware improvements with Canon 1D MKIII?
Many will want to know if the firmware and sub-mirror fix improved themarks of the Canon 1D MKIII. Yes. But only somewhat. Overall we show animprovement of 9%. The prior average was 40% Out of Focus for thistest. A number that is still better than the Nikon D3 received undereither round of tests and firmware.

Does this mean that overall I like Canon 1D MKIII better than Nikon D3?
No. It simply means that Canon still outperforms Nikon in thisautofocus category. The Canon 1D MKIII is a great camera. However, mytime with the D3 has led me to seriously question whether I would stickwith Canon in the future. I really like the Nikon D3. Some advantagesof the Nikon D3 over the Canon 1D MKIII for my type of photography arethe increased iso range, the increased resolution of the lcd screen,and the ease of setting custom white balance.

原圖下載
CANON


NIKON


exif自己看

他在網頁作手腳......
這種伎倆
算了吧

一個是300MM
一個是384.4MM
怎麼比
C-Focus ???就是連續對焦(他瘋了)應該是用3d追焦吧

我看這歐洲佬不是CANON賣家
就是白癡
當然我不是說CANON不好
只是.......算了吧

世上最NB的D3对焦不是靠镜头的，是机身的马达，什么时候出的头都是没有关系的。而且人家只看对焦，又不看画质。VR也是手持才用得到，这种测试都是三脚架+线控，有没有VR,IS 都无关紧要。

我也没有一定要说谁就是比谁好的，发个东西给大家打发下时间

AFS 跟USM都是鏡身內置馬達
當然有關西,因被攝者跑步.就需要連續對焦
當然有鏡身馬達對焦快及準
不然你以為canon雄霸大砲試場那麼多年是假的.靠的就是鏡身馬達快
世上最NB的D3對焦在AFS鏡頭上是不用機身的馬達的
想想那麼大的砲靠機身拉,會快才有鬼

話說我20年前就是玩canon
canon砲一直是我的最愛
只是買不起
也沒有指責別人的意似
讓大家誤會抱歉
