Unfortunately many of the lenses from &#8220;new&#8221; manufacturers struggle a lot in this category, so I am really delighted to be able to list flare resistance in the &#8220;good&#8221; column here, which only rarely happens. Maybe NiSi has an advantage here by using the knowledge on coatings and light baffles they gathered making filters and filter holders before.<\/p>\n<p>Now if you settled on the APS-C format to be able to use a smaller camera with smaller lenses you may very well be disappointed by the size of this lens, especially compared to the Laowa 9mm 2.8 APS-C. In terms of optical performance I do prefer the NiSi lens here though, especially because of its great flare resistance. So ultimately it is up to you, what is more important to you here.<\/p>\n<p>You see it from the table, the good list is long, the not good list is short and there aren&#8217;t really things on it that
