So I have this speck of dust whenever I shoot videos at a small aperture e.g f14/f16 in broad daylight 100 ISO.
I googled it and it said it is sensor dust, but my sensor appears to be very clean. I set my shutter to 5 seconds took a photo without lens and saw it, it looks spotless. Theres also a big piece of **** in my lens so could this small black dot be dust from the lens?
Its not very apparent on the pictures but when watching video playback its very dark and noticeable especially when the picture is panning and the dot is just sitting there.
