i totally forgot i bought this like 4 days ago!!
so i obviously took a bunch of pictures of brock
i weighed the blur vs his face and his face won on this one.
with very little exposure adjustments, i think these came out kinda nice. i could see this mainly being useful during cons when you stop costumed folks to give more balanced light on them with out stopping down or jacking up the ISO to unreasonable levels. well worth $40 in my opinion.
