Upon popular request, SLR Magic has decided to redesign the exterior of their HyperPrime CINE 12mm T1.6 lens for Micro Four Thirds, adding fixed gears around the focus and aperture rings (the previous CINE version of the lens had optional gears.) This way, the lens can be easily used with a follow-focus system in videography applications. For still photography, the added gears provide extra grip when operating the focus and aperture rings. Existing users of the HyperPrime 12mm f1.6 (non-CINE version) can have their lens upgraded to the current version with gears for US-$ 250.
