What A Find! Electra Zoom Prototype

What A Find! Steve Raymer at The Pavek Museum in the Minneapolis area has received some lens donations and this one is a real treasure. This is a very rare Walker Electra Zoom lens. Joe Walker worked with Frank Capra and made and designed special lenses to be used specifically on over 50 of Hollywood’s leading ladies. This is the first zoom lens. In the early 50s, Walker sold the company to RCA who continued manufacturing and improving this first electronic zoom lens, but kept the Electra Zoom name.
