What better way for a professional photographer to be unique than to use lens nobody else uses (in a good way). Artist Sharad Haksar provided this answer with his calendar lens. The material uses is aluminium it looks pretty good. The question that floats around is whether it will be automatic or will require some kind of manual operation to change the date… Also, be aware of the fact that the calendar can only display dates up to 2032, but until then many new things will certainly appear. You can order them from the artist’s website and they are said to be shipping in approximately two weeks after the order has been made.
