Ahh! That's what I wanted to see. Looks like it was designed to fit perfectly on the camera. I heard from some websites that the 52mm step ring's threads will cut its own threads into the Holga lensbody quite cleanly. That way, you can put filters on.
hey mark, the fish eye that eye use (excuse the joke) has a 52 mm adapter/macro lense on it for my cannon and it just so happens that the 52mm adapter/macro lense slips right over the lense on the holga, pretty much perfect, then a little tape so that I feel secure. I will take a pic with my digital and post it later, but it looks natural, believe it or not! thanks for looking
