Optical/Mechanical

  • Increase maximum aperture by 1 stop.
  • Increase MTF.
  • Makes lens 0.71x wider.
  • Felt material flocked inside to reduce internal reflection.

Electronic

  • Fast contrast-detection AF on all E-mount cameras (except AF-S/DMF with Sony A9).
  • Pure phase-detection autofocus support on A9, A7RII, A7II, A6500 and A6300 (the fastest).
  • Supports 5-axis in-body image stabilization of A7II, A7RII and A7SII. (Distance information from lens required; 3-axis IBIS if lens does not transmit distance information.)
  • Powered by camera body. No external power source required.
  • Efficient switched-mode power supply.
  • Supports image stabilization (IS) lenses.
  • Supports electronic manual focusing (e.g. EF 85/1.2L II and discontinued EF 50/1.0L)
  • EXIF support (focal length, aperture, lens name)
  • Distance and zoom display on VG and FS series camcorders, A9, A7 series, A6500 and A6300 (lens with distance information support required).
  • Auto magnify (lens with distance information support required)
  • Auto "APS-C Size Capture" on full-frame cameras.

Limitations

  • 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".
