It looks like Yongnuo will soon be releasing a new manual focus macro lens, the YN60mm f/2 MF. (thanks Bali)
|Lens Construction||9 groups 10 blades|
|Aperture Blades||7 blades|
|Min. Focusing Distance||about 0.234 meters|
|Size (DxL)||about 76×115mm|
Although it’s not specifically stated in any documentation that I can find, it will at least be released in a Canon EF-mount version as the product pictures clearly show a Canon mount.
