The SIGMA
1.4x Teleconverter, is a dedicated APO teleconverter that can be mounted
between select lenses and the camera body to increase the focal length by the
power of 1.4.
The new multi layer coating reduces flare and ghost, which is a common problem
with digital cameras. They demonstrate best performance with DG series lenses.
They also offer maximum photography magnification by 1.4 x, without any
variation in the minimum focusing distance.
Compact and lightweight, these teleconverters convert your lenses into longer
focal-length lenses, so you don't have to do a lot of unnecessary footwork.

| Usable Lenses and Combinations |
- Sigma APO Tele Converter 1.4x and 2x are dedicated Tele Converter lenses, which should be used with listed lenses only.
- AF function of Pentax mounts cannot be used with SFX/SF7 cameras.

| 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.

|
| 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.
*Dimensions and weight include the Nikon mount.
**Appearance and specifications are subject to change without notice for improvement.
