Variable filter
Use the 72mm version on a Sigma SD 14, fits perfectly and saves me many, many different darkening filters. A really great thing, didn't even know that such a thing existed. Previously had 4 pieces of different gray filters, which I could now do all out of the bag. Sounds like a lot of money at first, but I only calculate the expenses from my 4 filters...oh oh I would have gotten off much better here. Now I can !infinitely! adapt to all lighting conditions, a dream.
