Some lenses will operated in AF even though the list of MINOLTA AF, NIKON AF, PENTAX AF mentioned "MF", however, be aware that these lenses cannot focus precisely by auto focusing. Therefore, please use such lenses in MF mode when a teleconverter is attached.

If using a lens which has "o" in the list, the camera's display will indicate the converted exposure information. If using a lens which does not have "o" 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.
