MD Minolta MC lens focal reducer speed booster adapter to Sony NEX 5 6 7 FS700 FS100 VG20 EA50

 

Focal reducer/Speed booster adapter

for/Minolta MD/MC bayonet lens to Sony NEX mount 5 6 7 camera FS700 FS100

All metal structure, with excellent opticals (4 elements/2 groups, super multi-coated)

what it does:

• reduce the focal length (by 0.72x wider)
   

• Ex. 50mm lens on NEX with the adpater, eff. focal length is 50mm x 1.5(crop) x 0.72 = 54mm

　

• 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).

this new version is made to overcome the a)blue spot b)slight green tint issues in the old version
 

the edge fall-off is still to be expected though, this is by nature, not a design issue
 

　 what it does not:

there is no electronic integration, no auto fucusing

　

　

　

　

(note that if your lens has extended protrusion on the rear, please be careful, as it might get in the way with the opticals inside)
