Compatibility chart



Compatiblity

  • SIGMA APO Tele Converter 1.4x and 2x are dedicated to Tele Converter lenses, which should be used with only listed lenses.
  • Cannot be attached to a camera and lens whose mount is different.
  • Cannot be used in combination with another APO TELE CONVERTER EX DG or other manufacturer’s converter. Only one tele converter can be used at one time.

Attaching the APO Tele Converter to the Lens

First, attach the APO Tele Converter EX to the master lens. Then, attach the lens and the Tele Converter to the camera body. If you attach the Tele Converter to the camera body first it may cause a malfunction.

Exposure

Using the APO Tele Converter EX decreases the effective aperture by one F-stop (with 1.4x Tele Converter) or by two F-stops (with 2x Tele Converter). Regardless of exposure mode, correct exposure can be obtained.
If using a lens which has in the list, the camera’s display will indicate the converted exposure information. If using a lens which does not have in the list while using a hand-held exposure meter, you should increase the exposure reading by 1-stop for the APO 1.4x Tele Converter EX or by 2-stops for the APO 2x Tele Converter EX.

Focusing

On the lists, the lenses marked “AF” will retain auto focus operation when used with a Tele Converter. The lenses marked “MF can only be used for manual focus.
Some lenses will be operated AF even the list of NIKON mentioned “MF”, however, be aware that these lenses cannot focus precisely by auto focusing. Therefore, please use such lenses in MF mode when teleconverter is attached.
