7artisans Handheld Diopter Effect Filter (+1)

The +1 7artisans Handheld Diopter Effect Filter is recommended for 50-105mm focal lenses and can be easily controlled with one hand to achieve blur effects, tilt and shift effects, and special light spots. The larger the diopter, the more blurred the effect is achieved. In actual use, some photographers like to wear a hood so that the diopter is a certain distance from the lens. Because the diopter is far away from the lens, it is equivalent to a longer focal lens.
