Opteka recently announced the development of five new MFT lenses. The first MFT lens will be 6.5mm f/2 HD Multi-Coated Circular Fisheye Lens. Those are the specs:
6 elements in 5 groups
9 aperture blades
1.9” (0.05m) minimum focus distance
Opteka currently sells some lenses for the FT and MFT system on Amazon US, Amazon DE and Amazon UK. But those lenses were originally designed for DSLR and later adapted.
