Secondly, with recording video, we virtually all the time apply stabilization utilizing Gyroflow or RockSteady, the picture will get cropped barely, which usually eliminates the darkish corners.
It’s a pity that the filter equipment doesn’t include a micro fibre fabric for cleansing the lens, perhaps I’m asking an excessive amount of at this worth level however it will be good it’s included.
