新的測試用小光圈標準zoom鏡, 光圈小於2.8, 對焦測試的比試結果沒大意思。

去年用50mm/f1.4測試對焦比較才像樣！

看到Number5懷疑是否有用機頂輔助對焦

CAPA測試時，是用強光照射，使測試環境保持在EV9

所以機頂輔助對焦沒什麼意義!!

Let me tell you what I think of these test, while most of Japanese Magazine"s test are fairly informative. The test done by Capa, Digital Camera digest and alike are no where near anything usable, as the environment is not quite as controlled as they seems to be when you take note of how they test.

And regarding the exposure - 光圈固定F4，1/30秒，ISO100 - does that really matter, you are talkign AF accuracy - that part of the camera is indepndent of these. One major fault they have with these test is using the lens choosed. These are all middle ground Workhorse lens and thus are subject to various degree of Mfr tolerance and variations.

If you should eb reading these AF accuracy test and been there for some time, you can tell even between different magazines and issues of same magazines. They have diversed resultd on this test, making this test fairly unstable at best ...

The only reliable AF accuracy test that even seems to surface is the "Nippon Camera" Test report on individual cameras since it used controlled lab environment and special test use optics - so on & so forth - and it repot on its finding both usign the test optics and also on Mfr lens making it more meaningful.

To FTL :

雜誌上的測試，雖然"看看就好"，但怎麼樣也比網路一堆不嚴謹的個人流言要好太多了

這個測試可以還 Canon 一個清白

Canon 賣的多，當然發生 "案例"就多嘛!!

我說還 Canon 一個清白，是指網路現在一面倒

好像全世界只有Canon一家會偏移，其他廠牌都非常棒

我本來就不相信，現在這個雜誌的測試總算澄清一些事實

怎麼啦，講到你的 D7D 很爛就不行嗎

你知道你在多少討論區列為黑名單嗎...

nfish,
   那你可以建議站方砍掉我的帳號阿，你可以當Canon Fans,就不能有人當Minolta Fans嗎？
7D我也不是沒用過，7D一些性能沒有D7好也是不爭的事實，我可沒有一味地幫KM護短。

jun65,
   我看目前大概沒有一台數位單眼用任何一顆鏡頭拍出來每次都零偏移的，我認為最好標出該測試鏡頭的偏移程度是否在景深範圍內，這樣會更有參考價值，要追求零偏移現在大概是不太可能，但是要挑一款搭配多數鏡頭偏移量都在該焦段光圈全開的景深範圍內，應該比較容易，還有，我不姓余。

其他機種不熟, 但是20D來說....沒啥好意外的阿....20D雖然會偏...但是大部分時候...都是差不多的誤差,不會亂跑...只要熟用全時手動焦就可以解決.

唉....這讓我又在 20D 和 D7D 之間猶疑

根據以前出遊拍照的經驗
防手震+高 iso 是非常必要的
架腳架會被白眼..搞得氣氛很不好

可是說真的,除了篇焦問題
20D cmos 成像的結淨度很吸引人

另一個重點是...20D 比 d7d 便宜呀...
可是聽說 50F1.4 很容易掛點..

很猶豫說
