• basic adapters do not allow control of AF, optical IS or aperture from the camera, nor do they record lens information in the image EXIF data
• adapters with an AF-confirm CPU chip may allow:
  • manual focus confirmation on dSLRs using the camera's AF sensors to detect when a subject is in focus
  • some may allow recording of a pre-set focal length and aperture into the EXIF data of an image - this needs to be programmed.
• some adapters are fully electronic and allow AF, optical IS and aperture control
• some adapters are special purpose such as tilt-shift adapters

• these allow dSLRs (but not mirrorless cameras) to display when subject is in focus during manual focus using phase contrast AF sensors
• AF-confirm does not work in Live View mode and thus does not work on mirrorless camera systems
• these will cause an error if directly connected to a Panasonic camera - use basic adapters instead.
• the most common chip used is a Dandelion programmable chip which you can buy separately and glue to a basic adapter.
• search Ebay for cheaper Chinese versions

• mainly for use with lenses without aperture rings - eg. Nikon G, Minolta AF, Pentax K, Canon EOS
• if you use an adapter without aperture control on these lenses, the aperture will be fixed wide open unless you stopped it down on a dSLR of the same brand by holding down the DOF preview button as you removed the lens - the aprture will then be fixed at the aperture set prior to removal of the lens.

• search Ebay for cheaper Chinese versions:
  • Big-is brand is preferable, nice aperture ring, less play, flange distance more accurate and less paint flakig=ng internally than the Fotga brand

• RedRock Micro LiveLens EOS-MFT powered adapter
  • uses a 9V battery via cable to power an aperture-control device as part of the adapter.

    • 2016 as of firmware v2.2 on Olympus OM-D cameras:
      • relatively fast PDAF support for E-M1 with certain lenses BUT NOT Canon EF 135mm f/2.0L lens which will not AF with the E-M1 but will do via CDAF on other cameras
        • this quirk arises as the E-M1 defaults to PDAF mode only (and no CDAF) is the attached lens is not recognised as having CDAF compatibility - unfortunately user cannot force the E-M1 to use CDAF mode
      • relatively fast CDAF on cameras excluding E-M1, including face detect AF
      • multi-pt area AF, C-AF and AF tracking modes do NOT work well
      • OIS works if lens OIS is ON but no dual IS support at this stage

• these adapters allow a filter to be “dropped in” to the adapter thereby allowing the same filter to be used irrespective of which lens is being used
• this is very handy when using lens with very large filter threads or no filter threads such as ultra-wide angle lenses or fisheye lenses
  • if only they would make one for Four Thirds to Micro Four Thirds - be very handy for use with the Olympus ZD 7-14mm f/4 lens with a ND400 filter for long exposure bright sun shots of blurred water
• having a filter in place also allows changing lenses without risk of dust entering the camera body and landing on the sensor
• examples:
  • OWL drop-in filter
    • eg. Canon EOS or Nikon F to Micro Four Thirds or Sony NEX

• these are adapters which allow a variable neutral density filter within the adapter to change the light transmission without affecting aperture which is highly desirable in videography in particular
• variable neutral density filters tend to give weird artefacts on wide angle lenses
• Holy Manta VND
  • no ability to change aperture
  • Canon EF lens to Sony NEX or MicroFourThirds
