new optics design Focal reducer/Speed booster adapter

for/Pentax PK(A) DA AF lenses to m4/3 (mft) mount cameras

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

 

with aperture adjusting ring on the adapter !


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 fucusing
