Gemini. The Latin word for "twins" was the name given to NASA's second manned space flight program. It was fitting for two reasons: 1) the two-man crew that crewed the primary spacecraft, and 2) one of the primary objectives of the project was to successfully rendezvous and dock/undock two spacecraft. The program successfully completed all of its objectives by the end of 1966 and laid the foundation for the Apollo missions to the moon. Coincidentally, 1966 also brought twin model introductions from Minolta that would lay the foundation for their next decade of rangefinder cameras. The nearly identical Hi-Matic 7s and 9. Both featured Minolta's new CLC (Contrast Light Compensator) metering, which would serve as the top-of-the-line exposure measurement system for Minolta SLR and rangefinder cameras until the introduction of the AE-S Finder (1976) for the professional XK/XM SLR followed by the introduction of the amateur-oriented XD in 1977. Let's take a closer look at the Hi-Matics and the 7s in particular...
In 1962, Nikon decided to take the plunge into the amateur enthusiast SLR market with a new model, the Nikkorex F. From 1959 to this point, they only had the solitary, professional-oriented, Nikon F in their SLR lineup. The price of the F put it out of reach of the average 35mm photo enthusiast. In the meantime, Minolta and Pentax were cleaning up in the sales department in the amateur market, with Pentax having approximately four times and Minolta ten times the overall sales of Nikon in the whole interchangeable lens SLR market in 1962. This would prove to be a very consequential decision by Nikon, one that would impact their growth for decades to come. And not just in camera body sales. However, the Nikkorex F would fail to achieve Nikon's goal of successfully breaking into the enthusiast market. So it was back to the old drawing board...

With the longest-lived current 35mm SLR bayonet-mount (introduced in 1959), Nikon has a vast catalog of manual focus lenses in a sometimes dizzying array of variations. This can make choosing the right one for you seem daunting. Hopefully, we can help you to find the most suitable candidates for your Nikon lens (Nikkor) arsenal. In our first Nikkor article, we looked at the best bargains in single focal length (prime) lenses. In this follow-up we will attempt to peruse the bargain bin for zoom lenses. "Bargain" is relative in this case to other Nikkors in the same general focal length range ;-). Nikkors generally have higher prices than other Japanese brands of vintage glass because the mount is still current and because of Nikon's reputation as the "choice of pros" over a period of many decades.
Suffers from a two-decade and counting film and manual focus SLR addiction. Has recently expanded into 1980's AF point and shoots, and (gack!) '90s SLRs. He even mixes in some digital. Definitely a sick man.
