I recently bought a 40D with sigma 17-70 but for some reason output seems out of focus and not sharp at all. my G7 is much much sharper i thought it was hand shake problem so went and buy a sigma 18-200 OS but output is the same. Now wanted to cry and dont know what to do.....can C hing all give some advice. can be in chinese also i just want to type fast in Eng.....

駛乜買支is 鏡黎試呀?=,=
買腳架咪得囉~

在天朗氣清下拍攝看看結果怎樣?1/200秒或以上跟本不會手震.
或者閣下的鏡頭跟機身不配合.
不如找支原廠canon鏡試一試,如情況一樣即相機有問題.

相關問題已講過多次，綜合各影友/大師經驗如下：

1) DC 的色彩比較討好；

2) DSLR 的出廠設定比較色淡，較方便後制；

3) 細的感光片 (CCD/CMOS) 景深較大，使照片看來清楚一些。

樓主o既問題，可以在機內改一下相關設定：如反差、色彩、焦點(sharp/soft)，甚至加減曝光值，找出自己滿意的心水畫面。

為左試手震去買支鏡

樓主你都幾有錢

唔使cry?撻d相黎睇下!

G7用 Ｆ2.8 影出黎ge大景深

40D要用Ｆ8先影到

Your EOS 40D is too bad.

乜唔係係話佢部 G7 is so good 咩？

post相黎睇下先. 冇相冇得講

相片好多時都有個人主觀思想．用機都係自己滿意那一種就用囉．為了少許點位去追求，有錢的例外．

多謝各位師兄
小弟安靜後再看一編所有相片包括這一兩天拍出和沒看的,發覺一部份單目標如花可拍出非常好解像,但在家拍像用DC snapshot 般的全影要所有物件清楚對焦就有困難,請指導。
相信是技巧及調校問題，但例如在家相拍出如dc snapshot什麼都清楚,前後景清之白痴相應什樣倣呢？ 好多時覺得對焦不夠清又是什麼原因呢？ 謝謝大家鼓勵！

DC 全sharp 的效果, DSLR是不能做到的。簡單D講，DSLR的CMOS 是大過G7 的CCD. 越大的CMOS sharp的範圍越小(景深淺)


可買支 Sigma 10-20mm 試試，應該可以sharp 多D

haha

收f16光圈都得架

Use small apeture can provide a longer depth of field (f 11, 16 and above) but too small apeture will reduce the resolution ability of the lens.

One of the reason people prefer DSLR over DC is short depth of field for portrait.
