SIGMA做不出光圈1.2的鏡頭嗎？

SIGMA做不出光圈1.2的鏡頭嗎？

號稱擁有外星科技加持的SIGMA在出品ART系列35mm跟50mm都挑選了光圈1.4來製作

為什麼不能挑戰1.2？就連SIGMA的85mm都一樣光圈只做到1.4而已........

難道有什麼不為人知的內幕？

既然要電原廠鏡，為什麼規格不做一樣光圈1.2呢？

另外，即便是CANON原廠在35mm、24mm最大光圈也一樣只出到1.4

為什麼沒有35mm 1.2L 或 24mm 1.2L？

反而50mm 85mm都能做到1.2大光圈

焦段再往上100mm 135mm光圈都是2.0起跳

是因為光學設計的關係所以才沒辦法突破嗎？

做出來太大太重也許是個考量，不過50L 1.2 仍然能保持輕巧600g以內與1.2大光圈
85L 1.2也差不多1000g

BIGMA最拿手的就是將重量升級提昇畫質，怎麼不勇於嘗試製作多顆1.2甚至更大光圈的定焦鏡呢？
相信即使重一點，版上眾多大力神人也一樣會買單的！
