我的裂像對焦很有問題:
用其中2 枝鏡時就十分準
用另外兩枝卻有些偏差:
上下影像如果沒有裂開, 卻會失焦, 需要輕微裂開, 才準,
其中一枝是c/z50mm f1.4, 所以現在對焦有困難.

請問大家有何意見?

大家研究下

1) 自動鏡準焦嗎
2) 烈像換左幾耐呢
3) 烈像中部有否偏移
4) C/Y 接環係邊種, 在那買
5) 烈像型號

方便推測

1) 自動鏡準焦嗎-- 我4 枝鏡, 3枝是af, 都準
2) 烈像換左幾耐呢-- 不到半年
3) 烈像中部有否偏移-- 意思是不是中間的圓圈有否偏向左或右? 基本沒有, 但有些小些小偏上
4) C/Y 接環係邊種, 在那買-- 未買
5) 烈像型號-- Nikon F3

Thankyou!

有 D 亂
咁問世間兄邊兩支鏡有偏差呢?
c/z50mm f1.4 係指 Carl Zeiss 50mm f1.4?
咁咪要 C/Y to EOS 接環咯.......... But U said 未買????
Nikon F3 or K3 呢?

[問世間]

那兩枝是:
Tmaron 28-75 F2.8
用AF 對準時, 上下影張是輕微裂開的, 才會中焦; 我試過用MF, 調到上下影像沒有裂開, 卻失焦了.

另一枝是 Contax C/Z 50MM f1.4 是, 要接環, 但我還未有錢, 所以未買.
我照試用o個枝鏡, 出來就是, 上下影張要輕微裂開, 才會中焦.

而另外2 枝AF lenses 都完全沒有問題.

Nikon F3 or K3 呢?
是F3, 一定是


多謝cow_size兄!

F3 係機 Body, K3 係烈像 Model..Right?

[問世間]

但係, 你睇下:

係唔係唔係o個個呢?
個F3 唔係 個screen model呢?

問世間,

It is possible for Nikon split screen lost focus on Canon EOS system.
Without knowing which camera you are using - 10D, 20D, 300D, 350D?? can only share my experience here.

Contax FU-3 - works on 10D, 20D & 300D
Contax FU-4 - works on 10D & 300D

Since the thickness of each model is not the same, you could try different makes of split screen to try.
Equally important is practice, you need to know which point your eye can make the judgement correctly - i.e. to train your eyes and yourself. Remember AF is by the micro chips inside the camera and MF is all up to your self and the longer the focal length the easier.

Currently, I use FU-3 on 20D (without the brass bracket) and AF works fine with Canon lens, MF equally fine on Zeiss, Rollei lens.

May the above can help you a bit.

唉, 要換過塊

[問世間]

今日就大發現
我睇完gt2002講係厚度ge 問題, 咁我就試下加返塊銅片, 銅片我有 塊的, 一塊厚, 一塊簿, 我加簿的, 放在prism 同 裂像之間, 再試下, 點知由原本的上右下左, 變到上左下右, 好失望咁攞返塊銅片, 整返好部機之後, 循例都要試下影, 點知竟然正常, 冇事, 真係奇蹟

qt2002兄,

請問那裡有 Contax Fu-3 賣 ?

搵咗許多個地方都沒有。

謝謝.

可能係位置的問題，我今日都換左裂像，我問幫我換o個位大大，佢話塊銅片係用黎調校塊對焦屏的厚度。

nm168,

Try at the Camera Repair Shop at Champagne Building, TST. And ask for the thicker one.
