One of the most popular and long-standing film camera systems, the Hasselblad V, is going to be discontinued, the company announced Monday.

Hasselblad chairman and CEO Larry Hansen cited a "substantial decline in demand for this camera over the past five years" as the main reason to end production on the line of cameras that was first introduced in 1948.

Many iconic images, easily identified by the square frames the camera produced, were made with the Hasselblad V. Perhaps the most iconic images, however, were those during the Apollo 11 mission, which landed the first men on the moon.

As a tribute to the Hasselblad V, here are a couple of those images taken on July 20, 1969.
