我用50D +sigma 50/1.4 ,己作機內微調及收至F1.6 ,但仍然50%失焦,請指教,謝謝

继续缩小。

冇得攪,S50mm1.4的最大強項是(走焦)

後退幾十步.... ^^"

去sigma度cal鏡啦，好多人買呢支鏡第一時間唔係去影相，而係去排期cal鏡。

[米高phone]

咁攪笑,有準備買左支鏡第一時間就入廠,咁不如吾好買啦!人話神鏡你又信.

上星期我去肥花想買支死馬24.8
試左2支都走前1cm左右
個店員都話買死馬就要去cal
機身微調係幾mm
1cm幫我地唔到

viovanda Ching,

如果咁大問題點解唔攞去Sigma cal 嘅 ??

我用咗幾個月好彩暫時又唔覺有問題, 而且我買果時試第一支就OK, 咁我都要買六合彩啦~~~~~

查實我都想問下, "真正"買咗又用緊S 50.4 嘅Ching.......
有幾多個買咗冇問題??
有幾多係走焦要cal??
又有幾cal 極都仲係走??

等我知道係咪真係我咁好彩~~~~~~

my Sigma 1.4 is a very very sharp lens if using liveview, but suffer from front/back focus issue, even after extensive calibration. My solution: sell it.
Now only keep the EF50/1.4 & 50/1.8

* my S1.4 is very strange on my 5D2, if shooting horizontally, the front/back focus problem occurs frequently, but if shooting vertically, the problem is not that serious.

我之前用40D cal 左次,叫做少左,20%到 , 而家換50D,自己用微調tune 過,响屋企影報紙甘樣tune,冇問題,但一出街用就死,支鏡真係好正的尤奇ｄ背景柔到直迫Leica ,冇理由吾要佢買支c 50/1.4架??又冇其他可从楝

[look_yau]

我都係鍾意 C50.4 多啲 ^_^

[look_yau]

同埋你都係收至F1.6 -_-!!
試下 F2.2-2.8 個問題有冇好啲

我之前用sigma 50.4,cal了2次都走焦,於是喺哩樹同一位師兄交換(他補了幾百元給我)了支canon 50.4,支c用咗接近3個月(大約用了4次)發現原來都係有走焦,不過就無sigma哥支走得咁利害,想同大家講原廠都一樣會走焦嫁. >.<

[layer]

um.... 話時話,sigma雖然走焦利害,但支50mm又真係靚過canon 50.4(無論色水成像散景),有d後悔同人換左支鏡,但走焦關係唔換唔得.

[look_yau]

走焦影唔道支鏡更靚都無用
