Extreme Telephoto Lenses

Extreme Telephoto Lenses

The lenses on this page are extremely rare, and are no longer manufactured. Each represents different milestone achievements in design of photographic optics. These lenses are "collectible" in that devotees of advanced photographic optics purchase them because they are rarely seen on the market and generally increase in value over time. Each of the lenses listed is in outstanding condition, almost like new. Please refer to the descriptions for details. The lenses, with the right adapters, can be used with digital still cameras or c-mount video cameras (please contact us for additional information).

The 1200mm Canon lens below is the longest primary lens ever manufactured. It is extremely rare, and in superb condition. When the included 3X converter is attached, a 3600mm focal length can be achieved (a 12" ruler shown below for scale - this lens is incredibly powerful). It has a built in filter holder for easy insertion of filters in the light path.

B.T.L  30 Inch Military Bore-sight Optical System

L1

This is a very unusual and rare military lens. With a focal length of 30 inches, the lens itself from hood to rear lens cap is about 35 inches long. All of the optics appear remarkably clear for a lens of this age, and the adjustments all work well. The white paint is worn off in some places, the there is no evidence of any damage to the lens. The objective lens glass is 3” in diameter (the lens body at the front is about 4.5”). The rear lens glass is 25mm and the threads appear to be 50mm. This appears to be a prime / objective lens of some sort. You will need to work out your own mounting system.

The lens has a built in switchable red and clear filter, manual focus and an additional adjustment that ranges from 0 to .9. There is also a right-angle viewing lens of some sort which threads onto the lens body. In addition to this antique lens, there is a modern set of 2 clamps and mounting rail with standard mounting holes. 

The itself lens weights about 15 pounds. The trunk is wooden, very heavy and sturdy with handles, and it is felt lined. The lens has a built-in desiccant chamber.
