本人用 f100 很難做到景深淺. 如用 menu - f2.8 , 只能不zoom 近, 不沒有景深淺效果. 如zoom 過去, 只能f4.5. 如何可拍攝到大光圈, 景深淺...
如用f4.5 拍攝花或人像. 是否也可景深淺.

謝謝

Use max zoom is your only choice ! Set F2.8 is useless !

Thanks. But i have tried to Zoom in (f4.5) but still can't get it...

Not all photo can have this effect ! Last time I try 10 and only 2 of them works !

用macro去影大頭相就得
不過dc都係不能做到淺景深效果

真實焦距廿幾mm, f/4.5, 景深可以由3呎去到無限遠, 除左微距之外, 玩淺景深是不可能的, 放棄吧啦, 如果小型DC都可以做到專業效果, 萬幾蚊淨得個BODY的入門級DSLR冇人買了!

Consumer Digital Camera is not good at shallow depth of fied.

The only things that we can do is :
1. Arrange the object far away background.
2. Get colse to the subject as much as possible.
3. Set the largest aperture say F2.8
4. The most effective way is to use software to blur the background.

Note :
When you zoom in the aperture become smaller and the depth of field would increase. (FZ1 is an exception.)

INTERESTING NOTE :
If the size of the subject in the frame is the same and the aperture are the same, zoom at 35mm and zoom at 140mm provide the same depth of field.
If you don't believe it try it out, digital shots cost you just fun time.

Happy shooting !

請問邊部DC有 140mm 焦距鏡頭咁勁? 我真係未見過! 頂班的PROSUMER也只得七十幾MM咁大把! DC所說的幾百mm, 留意前面有「equiv.」字樣的, 是和135菲林機鏡頭的涵蓋角度比較而矣。

景深與以下三個因素有關:
(1) 鏡頭焦距: 焦距越長景深越淺
(2) 光圈大小: 光圈越大景深越淺
(3) 對焦距離: 距離越近景深越淺

如果影像佔感光面的比例相同, 光圈也相同, 長焦距拍攝的那張, 景深較淺。
