52mm FADER ND Neutral Density Filter Grey ND2 ND4 ND8 VARIABLE ND16 ND32 to ND400 DSLR Camera (Electronics)
the filter works on small NA value but as soon as one goes up a bit value is formed purple halo on the picture. necessarily at this price I did not expect a miracle, but I will at least be able to exceed 2 seconds installation time
