Kipon Baveyes EF-FX AF ”Speedbooster” Review

The Kipon Baveyes EF-FX ”Speedbooster” with Auto Focus works better than many of its competitors at its price point, but still has some typical lockup issues that require you to restart the camera. You can also experience some vignetting on the Fujifilm X-H1 because there is no lens correction for the IBS. Kipon makes a series of AF adapters below that all perform very similarly. If you do not want the Baveyes focal reducer there is a standard smart adapter and there is also one for the Fujifilm GFX. A beta firmware was also used in the review above.

Pros

  • 1.05x Crop instead of 1.5
  • AF and Aperture Control on Canon Adapters
  • Not Very Expensive
  • All metal build that is very sturdy
  • Firmware updates
  • Results are similar to other adapters, but a little less buggy than Viltrox
  • Works great for video with manual focus
  • Pretty good AF
  • Good for portraiture, landscapes, architecture, family, travel, etc…

Cons

  • Swirly Bokeh when used with some lenses that some might not like
  • Video sometimes has vignetting when recording on the X-H1 due to IBIS
  • ND sometimes creeps into the frame due to IBIS
  • Not as reliable as native lens
  • Not great for street shooting or sports
  • Video AF isn’t great
