我想知點解加wide angle後中間好清楚，但邊位好矇，請問點解呢？係咪因為角度同距離唔同？有冇方法可以解決？

[hkhei]

多數係因為鏡頭質素問題....
差唔多所有鏡頭都係中間o既質素好過四邊..

是不是加了 Converter? 多有此現象的. 收細光圈會好d...

我用Nikon 995 + E63 Wide Angle。

收細光圈會否令相片唔夠光？

if u use 光圈先決, 不會令相片唔夠光的 (coz 快門會自動變慢)； 除非你用手動,咁你就要自已較番慢個快門喇。

想問高手門一些相似問題

DC加左wide鏡後, 影遠景個距離反而要set做macro
何解?

想問下影wide 遠景的心得, 如光圈, 或其他要注意的地方.

先謝

我試過用唔同光圈影，F2.6, F5.3 and F7.5，發現用F5.3比F2.6 D邊位清楚得多，請問光圈用幾多先至係最好？

pitshing,

i think F 5.3 is ok.

Thank you very much!

yea, i have this promble either, when i use wide angle lens to take 遠景, but that would be 較矇, or i have to set it to Marco Mode?

[dogu]

on my very little experience, when a DC apply a wide angle lens to it.
The fact is that the real image object is built by the wide angle lens (not the real distance between the DC and the object) which is very close to the DC

So the distince now of the image object is extremely shorter and DC need to use Macro mode to focus this very closely object (image)

If further using the macro mode and still not obtain image well. The problem may be the two reasons:

1) distance between wide len and DC is not FAR enough. you have either to add some step up step down ring between DC and lens (but it may bring out black corner problem)

2) wide angle len quality problem but most of time using wide angle len will greatly decrease the resolution of the image (if not focus problem) anyway.

So, my suggestion is: if you really no need to use wide angle under DC(only), don't try to buy one for playing or it may give u bad expectation. :)

Thank you very much dogu, thx for those informations, it's very useful, now i understand how comes it can't frocus very well la , thx x 9999 to dogu !!!
