Nikon Speed Booster XL MB_SPNFG-M43-BM2
The Metabones Speed Booster XL 0.64x adapter concentrates full-frame Nikon G lens light onto Micro Four Thirds sensors, increasing brightness by over a stop while widening the angle of view. Its 50.9/100 portrait score reflects effective shallow depth-of-field results, despite lacking autofocus and stabilization. This adapter is best for portrait shooters adapting Nikon G glass to MFT, but its 15.3/100 macro score makes it unsuitable for close-up work.
