Nikon Rangefinder 250/4 Manual Aperture
Nikon's 1st "Super Telephoto"
The 250/4 Nikkor was introduced in 1951, to work with the original Nikon reflex mirror housing on the Nikon S rangefinder. It was the first longer than 135 lens by Nippon Kogaku for their new 35mm camera line. The earlier manual aperture version with a production of about 600 is much harder to find than the later preset aperture version introduced in 1956 with a production of about 1700.
This lens # 271835 (most likely the 35th 250/4 Nikkor) is an early 1st 250/4 manual version NOT documented in any Nikon reference book I have been able to find. It has unusual features not found on the later and much more numerous and well known Type 2 250/4 manual aperture lenses.
Weighing 49oz without hood, the Type 1 is 9 oz heavier than the Type 2 250/4 manual Nikkor
The focusing ribs are evenly ribbed, without the more common fluting found on later 250/4's
The lens hood is about 30% than the later lens hood, measuring 85mm long.
The lens hood is only marked "Japan," not "f=25cm 1:4 NIPPON KOGAKU JAPAN"
Estimated production of Type 1? Perhaps 50? If it has taken this long to be documented, production figures for the Type 1 250/4 manual aperture Nikkor are obviously quite low. Number 271835 is the 3rd lowest serial 250/4 number reported to Bob Rotoloni. Bob knew of this early variation, but had not yet photographed it. This page will be a future article in the quarterly Journal of the Nikon Historical Society.
The tripod socket is fixed, not rotating. The 4th rear element is close to the rear of the lens, so handle carefully! The lens hood reverses for storage on the lens. While the lens hood separates to take Series 9 filters, the lens is also threaded for 68mm filters.
250/4 Nikkor Type 1 manual aperture Reflex Housing Nikkor mounted on the rare Orion Mirax mirror housing with 90 degree prism and black paint Leica M4. The Mirax was produced by the Orion Camera Company, manufacturer of the Miranda Orion camera. Even the cable release is Orion, as well as the Nikon reflex lens adapter mounting the 250/4 on the Orion Mirax Type A Reflex Housing.
