If you’re a Micro Four Thirds camera user, your ecosystem of accessories just got a tad larger. ZY Optics is today announcing their new Lens turbo adapters for M42, Canon FD and Minolta MD lenses to Micro Four Thirds cameras. The Turbo adapters not only let you adapt the lenses but also widen the field of view in addition to making the aperture shallower by one stop–just like the Metabones SpeedBoosters.
As far as tech specs go, the adapters have 4 lens elements in 4 groups, including 1 extra-low dispersion element which helps in reducing the chromatic aberrations on the image–according to the company’s claims. The angle of view of the camera lenses will be increased by 0.726x. So that means that a 50mm f2 lens will become 50mm x 0.726 = 36.3 x 2 (Micro Four Thirds crop factor) = 72.6mm at f1.4.
When they hit retailers, they’ll sell for $149.
