A couple of weeks ago I “invested” in a new lens for my Sony camera. As is the way of these things the filter thread is different and much larger than those of my other lenses, so I decided to get a new neutral density filter.
A few minutes browsing on Amazon and I clicked to order one made by Gobe. Decent reviews, sensible price, seemed fine. The filter arrived yesterday.
Inside the box is a voucher saying the manufacturer will plant five trees in deforested areas as a consequence of my purchase. I clicked on the link and it seems this scheme has so far resulted in over 1.2M trees being planted. This does nice things to reduce CO2 etc plus provide employment for people in job sparse parts of the world. Great idea, more camera companies should do the same.
