Sales Period

According to Nikon's corporate history, the EL Nikkor 210mm F5.6 lens was released in May 1968. Then when did it the sale end? I saw it listed in the Nikon price list dated April 1, 1984. According to the Nikon price list dated October 1, 1984, I saw the newly designed EL Nikkor 210mm F5.6A listed. Therefore, I estimate that the 210mm F5.6 was discontinued around mid-1984.

How to Use the Lens

The lens mount is a screw mount with a diameter of 72mm and P=1.0 mm. It has the same screw mount size as the Ultra Micro Nikkor 155mm F4 lens. I attached the Ultra Micro Nikkor 155mm F4 mount adapter and mounted the EL Nikkor 210mm F5.6 lens on the PB-4 bellows.
