Here is a photo of the War Memorial near Waikiki Beach. It's a war memorial built after World War One. It's actually an archway that leads into a salt-water diving pool. Apparently this was built long before the days of efficient swimming pool filters. It hasn't be used in years. There has been some talk about tearing it down which will make an additional 200 feet of beach. But they claim they will keep the archway as the memorial. The photo was taken with a Russian Jupiter-37A 3.5 / 135 MM lens. This is a very good lens to use with the Sigma SD10. All you need the an M-42
adapter.
