請問有冇ching用緊200mm f/2.8 USM呢支鏡?
對此鏡有咩評價??

小弟用550D, 想入, 用來影飛機及人像, 適合嗎??
請各ching指教, thanks

其實支200mm f/2.8 USM影飛機夠嗎?
因為屋企支龍仔18-270 vc 都唔夠。
如果唔夠, ching有冇其他建議?
請各ching指教, thanks

"屋企支龍仔18-270 vc 都唔夠"

想問下CHing係哪裡影? 唔知點先叫"夠"...
一定要好遠, 平平地都只有Sigma 150-500...

在赤鱲角南環路影

但我又想用原廠

[richardlee326]

順帶一問, C70-300 IS USM 用在550D上是否變成
<70*1.6-300*1.6=112-480> ?
咁是否長過支龍仔18-270 vc??

請各ching指教, thanks

係 apc-c 既機上面, 無論原廠 / 副廠鏡, 都會有1.6x 既 crop factor
龍仔 18-270 都會 x 1.6 = 28.8-432mm

所以...canon 200mm f2.8 唔會遠得過支龍仔 18-270....
中情原廠....就用c100-400..

唔該 cpkin ching, 又學多咗嘢!
