I bought many close up lenses that are placed in front of the goal. Unfortunately the optical quality always brings an unpleasant distortion difficult to correct in post processing. I have a macro lens 105 2.8. the windscreen enlarges enormously the details of insects while minimizing distortion. I carried everywhere with me and as soon as I get the chance, I place at the end of my 50 1.8 for a superb ultra lightweight macro lens and easy to carry. Parcels received a few days after order. Bravo and thank you.
