Teleconverter Compatibility chart Sigma APO Tele Converter 1.4x and 2x are dedicated to Tele Converter lenses, which should be used with only listed lenses. AF function of Pentax mounts cannot be used with SFX/SF7 cameras. Do not use the APO Tele Converter EX on top of another APO Tele Converter, or any other kinds of converters.
ATTACHING THE TELECONVERTER 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.
For Sony mount, when attaching the APO TELE CONVERTER with a serial number lower than 5000001 to the camera body, it will prevent the AF mechanism from working.
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 with a • 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.
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. In some cases, autofocus may work for some SONY AF, NIKON and PENTAX lenses noted as “MF”. Please be aware that precise focusing is not possible, so please use manual focusing when using a teleconverter with the lens.
