想問c hing,

D700 + 24-85MM F2.8-4

點解會有黑角係四隻角........
24-85mm, F2.8-4 ....係"d" 鏡來架wor...not DX ......

24-120mm better in FX end end

係唔係遮光罩呀 ?? 裝唔裝正先 ?? 用FX鏡都唔一定冇暗角.....

[ssannwong]

舊式zoom鏡廣角端2.8光圈有暗角好平常, 一般做法係收細光圈兩級(2.8→5.6, 4.0→8.0), 就可以減少暗角

呢支鏡其實用在DX機先好, FX上24mm2.8光圈時, 暗角最大失光可以有46.75%都得, 所以先睇到有黑角係四隻角

唔係舊果d 鏡係FF 機可以用到曬架咩?!

你用細D既aperture﹐F5.6 - F8應該就無問題了。

full frame機係比較易有暗角﹐DX 有crop factor所以先見唔到暗角﹐因為crop左。

如果5.6以上唔夠快既話﹐就推高ISO

D700 ISO control好好的。

但係點解我有時用2.8 光圈,
一時時d 相先有黑角?

[fwan67]

better use lens like 24-70 f/2.8 and 70-200 f/2.8, otherwise, you better throw away your D700, wasting money and wasting time.

[Zeiss_T]

I don't think so

[snoopybee]

Agree with Zeiss. Though I have LB2 and LB3, my 18-35 works very well as well.

Common myths : 2.8 must produce high quality pictures.

本人覺得﹐其實FX機跟本唔需要24-70mm..
wide既﹕一支17-35 / 14-24 ﹐
telephoto既﹕一支70-200mm..
中間個空段用50mm.. 行前行後就全cover..又方便又夠快﹐成像又好。

用24-70既話﹐wide又唔夠﹐ zoom又唔夠。 中段又唔夠50mm好﹐我覺得浪費金錢。

[fwan67]

yes, agree, and for 50mm, you may consider Sigma 50mm f/1.4

Very true~ 提唔起買標準變焦既理由~ 碌鏡又重又貴
但係室內Function就好有用
