new optics design Focal reducer/Speed booster adapter
for/Canon
FD lenses to m4/3 (mft) mount cameras
All
metal structure, with excellent opticals (4 elements/2 groups)
Note: lenses with
extended rear protrusion might not fit !
It was brought to my attention that lenses with some type of breech lock might not fit in with the speed booster, please check my 2nd picture in the gallery !
Note the blut dot may still occur if shoot direct into the light or with high contrast
REGARDING THE REVIEWS:
apparently one of the reviewers did not attach the adapter firmly onto his camera, please check the more recent review.
And I'll be happy to offer another review from my another customer (see below)
what it does:
reduce the focal length (by 0.72x wider),
(in other words, under the same aperture, you can use faster shutter speed (by 1 stop).
effectively increases the
maximum aperture of the lens by 1 stop
what it does not:
there is no electronic
integration, no auto fucusing, no auto aperture
