用在FF上，同支50 1.4比較過，50L在2.0-2.8焦外燈光都好似做到圓形而50 1.4唔得，在1.2到1.8都化好多，而50 1.4在1.4-1.8實好多，但50L開到1.2同1.4時燈光散景唔係圓形，會有一邊Cut咗，好似邊位明顯啲…有冇Ching知點解？點避免？

好似同光圈葉數量有關

I tried this with 85.8 before..........
I don't know exactly why this happened, but my shot included a fence in front just like your case.
Try another shot without the fence in front with same focus distance, the 一邊Cut咗 effect would disappear.

我在Showroom都玩過都差唔多…
