我由2月開始收到KM消息話會出firmware去fix backfocus 都等在差唔多兩個月，但到呢一刻香港KM都仍未有確實日期比到我地幾時fix 到!

究竟:

1) 幾時先出新o既firmware?
2) KM係咪真係可以用firmware去fix backfocus?
3) 如果下一版既firmware 仍未fix 到 backfocus ，我們是否再等下一版?
4) 如果fix 唔到呢個問題有無得退錢?

講真我開始無耐性再第啦!

之前買了支Sigma 18-50 F2.8, 發覺18mm段 outfocus 嚴重(不論任何環境)，試過換了幾支鏡都唔得，好煩呀 :V ，都唔知係鏡事定機事! :-(

呢兩三個月不斷係sigma 及 KM 修理部來來回回! 而家對住部7D 都無晒心機影相呀! :(!

講真o係呢度問都唔會有答案, 似乎發洩多d~
會唔會係支鏡出事? 有冇試下用其他鏡都有BF問題?

KM有冇同你講部機實側有冇問題,有冇CAL過機??死馬又有乜嘢講?講泥大家分享吓,須然我唔係用KM都好想知乜事
我有二支死馬,都好準喎,反而原廠有D LENS唔準,一次拎二支鏡連部機番去CAL CAL完機D死馬鏡都係咁準

Have you used the original KM lens? is there any backfocus problem? Or is it related to other brand lens problem only?

失焦似乎唔關firmware事,主因係相機調焦部份!!

多謝大家的意見:

我的minolta 50mm F1.7 、minolta 舊鏡 28-80 F4-5.6 及 Tamron 舊鏡 18-200 F3.8-5.6 一般情況對焦好準(指在光環境加上對比度高)，而Sigma 18-50 F2.8, 18mm段 任何情況都outfocus 嚴重。

相機已換過一次，亦cal 過兩次都無問題(KM 話)

算啦，可能好似jammy_2002i 兄所講都係無乜答案！不過想知道下有7D 相機的師兄有無我同樣問題..

我用

SIGMA 18-125 + TOKINA 80-400
對焦好準未試過backfocus,outfocus

[jammy_2002i]

我用17-35 f/2.8-4D 同埋85 f/1.4GD都唔係太覺會出事...

I have BF always in low light environment with the lens I've - 35/1.4, 50/1.4, 85/1.4, 28-70/2.8.

I read some news which said that KM will reduce the investment on DC (not sure whether this includes DSLR) because of financial difficulty. I doubt they have resources to solve problem like this (they are hurry up to release 5D in order to get more earnings).
