If I have 10k budget for upgrade to shot small bird (smaller than 40cm),
which is the best choice?

1. 400mm 5.6L
2. 300mm f4 IS

My current setup is
350D
kit len
28-135
70-200f/4
1.4X
420ex

已有1.4X，300IS足矣。
400+1.4=f8+MF，相當難用也。

300 x 1.4 足夠嗎? 和現在我的70-200f4 x1.4 會唔會分別不大呀?

多謝回覆

don't for get 350d is not FF, so need x1.6 first ...
if 300mm * 1.6 *1.4 .... !!!!!

要打雀.....幾長都唔夠.....
不過我以前用300mm + 1.4x已經可以打到NSW既雀.
300mm我覺得平時都可以用得到.
stage / sport / gal~

500 mm la.

[joe chow]

10k budget only :)
so, only consider 300mm 4L IS and 400mm 5.6

40cm long is a large bird!!!!!not small!!

[joe chow]

no money, so only can treat 40cm bird as small bird la!!

靈活性,我一定投300mm F4L IS一票.
我之前都係擁有呢一支鏡,好好用.
對焦快,IS好有幫助,
加上1.4X都已經有420MM,有IS...
不過就對焦速度減小小....

300/4IS, 400/5.6

最後我揀左400/5.6 ^_^

What is your feeling of using400 f5.6?
Is it difficult to use and only be used in very good weather?

Anyone know the quality between these two lens?

[spchik]

我用俄仔500,f8. 好處係輕同平.

但要全手動.睇相的話可比 send你,因我未識 post D相.

我朋友就用300/4IS & 大白
雖然400 光圈係5.6 但係鏡片數目少, 個viewfinder 好明顯光D, 對焦速度比起300/4 + 1.4x 同 大白快. 次次打雀我都係用呢支鏡, 天氣好壞都係佢 ^_^
