沒技術的人只好買器材之菜頭到我家

前一陣子才買了Voigtlander Notkon SLII 58/1.4 .
一來用起來顏色太淡雅, 不是非常喜歡, 二來姊夫也搶了一隻, 又失去了用冷門玩具的樂趣.於是我又把目標轉回原來絕得太貴的Zeiss ZF 50/1.4
哪知馬上看到一隻二手的菜頭, 遮光罩前後蓋都在, 還附B+W MRC保護鏡.
馬上電話一打, 家裡就多了一隻"蘿蔔"了

馬上借用老婆的D700...沒有裂像對焦屏果然容易失焦阿...
不過, 一來色澤回到我比較喜歡的色調
二來, 為人詬病的邊緣成像不銳利, 正好投我喜愛凝視感的怪僻
只能說, 鏡頭好不好, 還是看相機後面的大頭...
比一下色澤的差異, 同樣光圈2.0, ISO400, on D700
ZF 50/1.4

SLII 58/1.4

難題: 出門帶哪一支好啊?

OH...抗氧化劑別吃太多阿: VITAL TRIAL

Long-term Use of β-Carotene, Retinol, Lycopene, and Lutein Supplements and Lung Cancer Risk: Results from the VITamins And Lifestyle (VITAL) Study

又來了, 一個針對beta胡蘿蔔素等抗氧化劑與預防肺癌的研究. CARET trial證實吃太多這些東西會增加抽癌者得肺癌的機會. 對於不抽菸的人呢?

Longer duration of use of individual β-carotene, retinol, and lutein supplements (but not total 10-year average dose) was associated with statistically significantly elevated risk of total lung cancer and histologic cell types; for example, hazard ratio = 2.02, 95% confidence interval: 1.28, 3.17 for individual supplemental lutein with total lung cancer and hazard ratio = 3.22, 95% confidence interval: 1.29, 8.07 for individual β-carotene with small-cell lung cancer for > 4 years versus no use.

簡單來說危險性是增加的.

Long-term use of individual β-carotene, retinol, and lutein supplements should not be recommended for lung cancer prevention, particularly among smokers.

結論是沒事不要多吃~~~
