50MM F1.8D 光圈2.0就利到不像話了.......看來您應該是根本沒想用過這顆唷。

大光圈的鏡頭好像都難逃這種命運 雖然我也都是大多用到F2.8在拍 因為F2.8時 真的是超棒的

雖然它發色淡很多,但是也是不錯用 可惜心裡的小惡魔 一直想換50MM F1.4D......
這一顆 50F1.8 和C家的一樣 是很利 不過 也立體不起來...就是這個原因

目前有打算脫手30 1.4來換人像鏡
目前考慮 sigma 50 F1.4 或 50-150 F2.8

幫您過濾一下...
sigma 50-150我也哈很久了,打電話問過幾間店,也跟恆伸也接洽過幾次,結論是:
已經缺貨好幾個月,日本原廠方面最近3各月內也無排定生產,所以若要這支也許只能考慮二手的...

50mm F1.8D的利好像很出名吧,我前面是說它很利呀...

50mm F1.8 @F1.8 , "立體不起來?" 是說3D嗎...

會不會是移焦了

很多鏡頭大家怪光圈全開的照片鬆散,最後問題往往是移焦(特別是輕微的),

所以縮光圈會"銳"...那是因為在景深內了...

Hahaha, me too.

I have been searching for a all purpose portrit lens for a while. After checking out hundreds of photos from FLICKR.COM I found Sigma 50-150mm F2.8 is my ideal lens for mid to long range portrait lens.

Overall speaking, other than Sigma 50-150mm is designed for APSC bodies which you can not use it on FF bodies. I really think this is a good lens for me.

The other day I went to Sigma Taiwan in Taichung to cali my Sigma 50mmF1.4 and saw this Nikon guy with D90 and 50-150mmF2.8. He was nice enough to let me try his Sigma 50-150mm on his D90 body. Boy, am I shocked at how this 50-150mm performs. Amazing bokeh and color is excellent. Even at aperture swide open at F2.8 the lens performs so well on his D90. Man, I looked at my Canon 550D and I know the Sigma 50-150mm is my next general all-purpose portrait lens for me.

I tried Sigma 50-150mm at 50mm, 100mm, and 150mm inside Sigma Taiwan office 1st floor and found focus is quite accurate and if Sigma 50-150mm performs this well on Nikon D90 then I believe Sigma will perform as good as on my Canon 550D.

I don't know why Sigma 50-150mmF2.8 is not popular in Taiwan, however, I do see a lot of people choose this lens in Japan, US, and UK and some part of east Europe. Check Flickr and search this lens and you will see.

By the way, my local camara shop does not have in this len in stock. I called Sigma Taiwan and no luck too. Sigma Taiwan does not have this lens for Canon in stock too...... I guess Sigma Taiwan only wants to stock popular lenses. To them, Sigma 50-150mm is not popular and maybe that is why there are so limited quantities available in Taiwan.

My friends ask me why I want Sigma 50-150mmF2.8 when I already have S50F1.4 and C85F1.8 and Tamron A09? Well, I guess the flexibility of having 50-150mm at F2.8 is my top reason.

Cheers and have a nice day.

50MM1.8跟1.4
我手邊都有
實際使用上1.4大概要到1.8才有銳度
1.8的實際大概2就相當銳利
所以常常我覺得
買1.4跟買1.8好像差不了多少

立體的問題你可以分兩個層次來看
全幅或者光線與角度
都會造成較立體的呈現

實際建議錢多1.4爽錢少1.8也沒有不爽
這兩天買了SIGMA 85MM 1.4
剛測試幾張
用在D700上面
真的還蠻爽的
^^

人像鏡未必是定焦
長鏡頭也是可以呀

剛入手D7000,對焦用AF-A模示,Nikkor 85mm F1.4D,照人像。我很滿意!

大大對焦點在耳朵上方, 眼睛已在景深外了。

這張真的是對焦在耳朵,因為側面,我貼這張只是想看看1.哪邊不銳? 2.哪邊立不立體?

倒不是在測移焦^^ 不過感謝你說,那我換一張對眼睛的50mm F1.8D @F1.8的
