SF sent me a new head and the new one looks alittle different. I hope I can explain this clearly. The end of the new one looks like the KL heads with the "indentations" instead a solid strait piece of metal. If you look on page 36 at the picture of the KL5 head, the end piece that holds the lens in looks like what they sent me. It doesn't matter and the new one doesn't leak. Just wanted to know. Thanks
