I was taking a few shots with my new lens(Sigma 17-50 2.8 OS HSM) and am very happy with the results so far, I was taking a few shots of Ollie and Banjo in the late afternoon the other day and noticed a light area in the bottom left hand corner.
I was shooting with the sun behind and to the right of Ollie so the lens flare was expected but am wondering if this effect at the bottom left of the images was caused by the cheap Inca UV filter I was using at the time? If this is the case can anyone recommend some reasonable filters to protect my lenses?
