new optics design Focal reducer/Speed booster adapter

for/Canon EF lenses to m4/3 (mft) mount cameras

All metal structure, with excellent opticals (4 elements/2 groups)


Note: Canon EF-S lenses do not fit !

(it 's for the full-frame EF lenses only)




what it does:

  • reduce the focal length (by 0.72x wider)

　

  • effectively increases the maximum aperture of the lens by 1 stop

  • (in other words, under the same aperture, you can use faster shutter speed (by 1 stop).




　 what it does not:

there is no electronic integration, no auto focusing, no auto aperture

　

　

　note some customers reported the blue spot occurs if shooting in sunlight or in ambient with high contrast.  Please be aware of this.
