我是一個學生 想買一部2手 D50
想知道有冇走焦 點樣可以睇到
唔該!

[yatsugiri]

首先準備一枝準確無比既鏡頭去試機.

quick test, 帶把間尺, 放平, 再45度係上面影落去.. 你對果到一定清.. 如果最清果點前移或後移, 就可能有 問題.

最好都係搵focus chart, 但出街試好麻煩.

撞過跌過 或者 機械組件wear off都會引起走焦問題

d2C:

your bird is "Out-focus" (<---- problem of photographer)
NOT
"back focus" (<---- problem of lens/camera combination)

突然飛埋黎無通知聲好正常.
好多前輩打雀 影 雀既飛行動態或者捕食. 唔見得有預先講聲 "我搵到野食而家落水喇"

呢個係攝影者同器材對焦速度唔及既結果. 點可以怪隻雀.

大陸就係怪動物, 所以係咁殺狗.
人有錯唔認, 走去怪動物, 悲哀.

d2c:

Please don't blame the poor bird.

D80 should have the necessary focusing speed to focus the bird, may be u were not using D80.

I guess u were USING THE D50 while shooting.

o... 原來 你同 obi有過節 =.=

不過佢話 走焦同 失焦係兩回事, 又係真既..

小黑5 有機會 focus 得切, 快得好過癮 :)

[老叟]

有過節/牙齒印無所為,因為現代人係無隔夜仇既,係咪????

[Obi-Wan]

d2c,

I don't know u, u don't know me. This is internet, how come I have to make trouble with u? If anything that I said annoying u, please ignore it.

I just pin pointed a fact to help people including u, "BACK FOCUS" IS NOT THE SAME AS "OUT-FOCUS"


The link

is a good place to test your D50 or other DC about back focus.

Enjoy photography.

"如何容易地看到走焦"

1. 調準接目鏡的屈光度
2. 清潔眼鏡
3. 沒有疲態時
4. 拍一張手動對焦、一張自動
4. 放大主體，比較兩張相片
