Note: Designed for APS-C/Super 35 cameras (e.g. A6500, FS5, FS7 Mark II, NEX-7); on A7, A7R, A7S, A9 and Alpha 1 use "APS-C Size Capture" mode. Before mounting the lens, set the adapter ring to 7. Nikkor DX lenses and third-party APS-C lenses do not cover the frame with the Speed Booster; Nikkor 2.1cm f/4 and AI-S 20mm f/2.8 are not supported either. Nikkor E-series lenses with electromagnetic diaphragm are not supported (e.g. 105mm f/1.4E, AF-S 70-200mm f/2.8E FL ED VR, AF-S 24-70mm f/2.8E ED VR, PC-E). Aperture is set manually with the adapter ring: no electronic aperture control, autofocus or image stabilisation.
