點影都係好夢幻
請各師兄幫幫手

- 支鏡係Sigma 17-70
- 部機個Sharpness已經set 左Standard sharpness+2
- 對焦正常
- ISO快門光圈等 setting 同我用細機差不多

感激不盡 !!

盡可能使用較小的光圈吧
很多鏡頭在光圈全開時未必有太好的效成像
籍此提升四角甚至整體的分析力
如果效果仍不如理想的話最經濟的做法就是以軟件作後期加工
甚至以RAW形式紀錄以增加調整的彈性
雖不是Canon的User
但小第都試過以朋友借來的400D配以KIT Lens收細光圈後
再加以RAW後期以PS Camera RAW 推高一點銳利度
都能得出不錯的效果

映raw,再用canon那給software推高sharpless,一定做到你要.

1. test with FLASH *to minimize the handshake problem
2. test backfocus problem
http://photo.net/learn/focustest/

if u can get 1. sharp => try to shoot with f8/11 ON A TRIPOD
if u cannot get 1 sharp, u will discover that u may have backfocus problem

if u can get 1 sharp & no back focus problem, that may be your own problem

please see

唔駛試啦, 一於拎部機去返canon 整啦. 我識人用呢部機嘅個個都係咁.........都係呢個問題....最後都係要拎返去整...整完就sharp 番......都唔明canon 每次出機都有呢個問題..但又唔去改善......

[cy001]

是不是只在副廠才出現這問題,是要回廠CAL鏡,是不是?

[orabuln]

我覺得400d 唔係太差...
photoshop cs3 resize / 100% crop 直出...
機無(專登) set sharpness....

no need to return canon cs to check

becasue normally canon people use raw
it is far away sharp than jpeg


if you are using kid lens you can try at f5.6 ~f8 is better
normaly if the aperture set to big like f2.8 you have to sure than you focus to some big flat area than is ok

and also the picture look soft becasue the disign for support the canon
printer

but you can see the follow picture this is direct photo jpeg

is it sharp enough ??

[hanny]

it is shoot by 50mm f1.4 and flash 580ex 400d

Are you sure it's direct jpeg output? No post processed by Photoshop?

[steve yan]

I have read almost all Canon reviews at dpreview.com and had not noticed the sharpness issue for jpeg image. I also have read a lot of messages from Canon fans, and almost all praised Canon images both jpeg and raw, but quite a few of above messages suggested that one should shoot raw and PP for sharper images. Or, Canon users always shoot raw and PP for better sharpness etc. Does this imply that Canon produced not very good jpeg images without PP??? Quite strange to me. I would believe a more reasonable answer: the camera in question needs to be checked by Canon since no one can quarantee 100% satisfactory QC, including Canon.

但點解拎返CANON 調教過之後又sharp 番? 點解釋?
如果吓吓要用f/8 - 11先sharp...點解要買單鏡機, 點解要買canon機? 唔通貪佢d相大光圈時夠夢幻.....可能唔係部部有呢個問題, 但有呢個問題嘅機都幾多.....如果成日諗住佢有冇問題, 不如趁仲係保修期內, 點解唔拎返去check check 呢?
