Free your Sony DSLR! With a 0.71x magnification rate, now you can use your EF-mount Canon full-frame glass to bring out the full potential of your E-mount Sony crop-frame DSLR.
Key Features:
- Increase maximum aperture by 1 stop.
- Increase MTF.
- Makes lens 0.71x wider.
- Full-frame lens required. EF-S/DX/DC/Di II lenses are NOT supported.
- Speed Booster ULTRA is designed to cover an APS-C image circle which is not big enough to cover a full-size 36mm x 24mm sensor. On a full frame camera body (A7 series, NEX-VG900) the camera needs to have "APS-C/Super 35mm" set to either "Auto" or "On".
- AF-C tracking during high-speed drive at up to 10fps on Sony A9, A7III and A7RIV.

- Supports 5-axis in-body image stabilization of A7RIV, A7III, A7RIII, A7II, A7RII and A7SII. (Distance information from lens required; 3-axis IBIS if the lens does not transmit distance information.)

- Efficient switched-mode power supply.
