兩支都係有macro1:2, 都係低色散..請問邊支成像好d?

[kingkonghk]

要去到300mm先可以1:2架, 但去到300mm時好易手震, 我試過要用1/250先克服到, 要注意呢樣

thanks kingkonghk! 其實用得macro 我都預在要落腳架 (雖然我用7D), 請問你用緊sigma 定tamron? 成像ok 嗎? 我見個價千鬆d有macro 真係好抵.

[kingkonghk]

我用sigma, 成象幾好架, 不過光圈收dd仲好, 影快o既野變左唔係好夠光, 賣左, 換左sigma180

i buy tamron 70-300 already , but their focus speed too slow .
compare with kit lens d70 (18-70) and 50 (1.8).

[Rol]

I am using tamron 70-300 for my istds, the quality is so far so good with this cheap len $12xx only , and the quality is close to my kit len, but don't have too much expectation on the macro, it can't compare the macro with fixed focal len.

thanks neville_sitou 及 Rol, 似乎兩支鏡成像都不差, 以這個價位, 我都知Macro 已是bonus. 如果講對焦速度唔知Sigma 個支會唔會快d?

[neville_sitou]

in this price range , the speed is same .
even nikon 70-300 ED ,

[kingkonghk]

macro AF時好慢, 唔macro AF時ok架

含苞待放 這是我用Sigma APO 70-300 F4-5.6拍的
不過是用手動marco的,不過要夠光先好用!

呢2支鏡, 打下雀ok唔ok呢? ...當然要求唔會太高~
因為見人地用300mm f/4黎打雀,
sigma 同 Tamron...zoom盡得番f5.6,
唔知同定焦f4的光度係米相差好多^_^
...只知價錢相差勁多..XDDD

[neville_sitou]
