我有支canon 50mm f1.8, 值唔值得去換支50mm f1.4, 雖然唔多用到大光圈, 光學質素會唔會再好d ?

其實兩支鏡都係光圈收到2.8左右先至靚

The 50/1.8 at f2 beats 50/1.4 at f2!!!!

錢多就無所謂, 但講質素就制唔過~

Go & check清楚d...

明顯支1.4成像實過支1.8
而且1.4光d(阻光少d),
散景亦係1.4靚好多.

值唔值lee個問題就好見人見智喇...

並唔覺1.4的散景會靚好多....
加上開到1.4光圈的質素真係好鬆, 光圈係大左但質素都低左.
支1.4收到5.6就會見到色散勁過支1.8

兩支我都有,主要分別係
50mm f1.4-用USM motor,光圈葉較多,色水較好,f2.0打後很sharp
但缺點唔係無,當然較貴及變形略大於50 f1.8

50mm f1.8-平,輕,f2.5 打後光圈已很sharp,但f2.5前光圈反差及銳度很低

I have owned two 50 F1.4 before, they are obvious difference in optical quality. So, to compare with 50 F1.4 and F1.8, I think many comparision on Internat may not be objective enough.

50mm 1.8II 都改左用8塊葉，光圈葉片係一樣，唔再係六角形o既散景∼

最吾客觀o既都係人家講o既所謂靚野，好主觀同好多情意結，
依家上網越來越多人搞測試，自己睇過Ｄ測試再決定最好∼

係wor, 50mm f1.8 幾時轉左8塊葉片, 我果支都係5塊 bor
