The Yongnuo Y100mm F2 on the left, and Canon's EF 100mm F2 USM on the right

Chinese photo equipment manufacturer Yongnuo is set to launch a new 100mm F2 lens that not only uses a Canon EF mount but which also looks just like Canon's own 100m F2. According to websites Photo Rumours and Photo Gear News the full-frame lens will be priced at around $170/€160.

The lens has been made to resemble the Canon version inside and out it seems, as both feature eight elements, have a maximum magnification of 0.14x and an aperture range of F2 to F22. The Yongnuo lens arranges its elements in five groups though while Canon’s own model used eight in six. Canon’s EF 100mm F2 USM also has eight blades in its iris, against the nine in the Yongnuo version.

Price is also a significant differentiator as the Canon lens costs $500. Nikon Rumours expects the lens to also become available in a Nikon mount.

Yongnuo already sells 35mm F2 and 50mm F1.8 lenses in Canon and Nikon mounts with each mount having a corresponding barrel design to match of the camera brand’s own.
