The User's Review: LEC - Cherry Multi-Power Lens for Pentax K

Have  you heard of a LEC in photography? I know you will say no because LEC is a new word I created. A LEC is a multiple-function device of Lens, Extension tube and Converter.

At the mid-night of 12/18/2011, I found the LEC with a Ricoh body sold on ebay. The saller, Kevin J., described it as 'an unusual item that I have never seen before'.  Bought it and received today right after the Christmas of 2011. It's a four-piece device in a black container, made by Cherry in Japan. Guess that it was made during 1970s -1980s (?) since it is made of metal and no single piece of plastic. The four pieces are: a body tube, 2 lens cores (35mm lens and 2x converter) and a front cover.

To work as a lens, assemble the 35mm lens core and front cover onto the tube from both end. Cherry calls it as a wide angle f = 35mm, 1:5.6. Remember that there is no focusing and only one f-stop of 5.6.

To work as a extension tube, simply use the tube only without any others. It should be an 'auto' extension because the aperture blades are kept open except when shooting.

To work as a lens converter, take off the front cover and put in the 2x lens core.

It's a interesting device, my LEC. And later, I found that this kit was also made for different lens mounts and rebranded for Kitstar and Itorex.

  2. This is very cool and still relevant in 2021. Thank you for explaining how the lens works!
