Variable filter
Use the 72mm version on a Sigma SD 14, fits perfectly and saves me many different darkening filters. A really great thing, I didn't even know that something like that existed. I used to have 4 different neutral density filters, which I could now put all of them out of my pocket. Sounds like a lot of money at first, but I only calculate the expenses of my 4 filters against it... oh oh I would have been much better off here. Now I can! infinitely variable! adapt to all lighting conditions, a dream come true.
