Do not use the APO Tele Converter EX on top of another APO Tele Converter, or any other kinds of converters.
 
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.
If using a lens with a MINOLTA AF and attaching the APO Tele Converter EX to the camera body first, it may cause the AF mechanism to run idle.
 
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 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.
*1 With 1.4x APO Tele Converter, AF can operate between infinity and 1.2m. If the subject is closer than 1.2m, only MF is available.
*2 With 1.4x APO Tele Converter, AF can operate between infinity and 0.52m. If the subject is closer than 0.52m, only MF is available.
*3 When the Tele Converter is attached, the zoom range will be restricted to between 100mm to 500mm.
 
 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 "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.
