I shot the photo below to test my 50mm F1.8 lens
Filter: Hoya UV-Guard (mono coated)
I saw that there are some reflection at the bottom right corner of the photo. Is this caused by flaring or something else? Please advise.
I was trying to test the flaring of the lens and filter thus i put the room lights at the upper corner. They are 4 energy saving warm light bulbs.
