Cosina has released a Canon version of its Ultron 40mm f2 SL II Aspherical “pancake” lens, which has hitherto only been available for Nikon and Pentax. The Ultron is a manual-focus lens made up of six elements in five groups, and has an angle of view of 57° on full-frame and film SLRs. The release of the Canon version makes it the most compact EF mount lens ever made. The lens can currently only be purchased in Japan, for the price of 53,000 yen. N.B.: The illustration above depicts the Nikon version.
