Interesting photo piotr , I bet you tried to do some macro images at home. I like the texture, seems that have been done in photoshop . By the way, you can leave a review on your lens here if you'd like .
A very light weight macro lens from Olympus brand. With weather sealed and high aperture to achieve nice bokeh effect. It is designed for olympus owners to shoot macro photography.
