1) Precautions
- Turn off optical correction functions, vibration reduction (VR) and focus aid assistance modes before using Kenko Teleplus DGX tele converter.
- Proper work and accuracy of AF mode only when the lens has a resulting aperture* of f/5.6 or faster. If the resulting aperture is greater than f/5.6 manual focus is strongly recommended. *resulting aperture = wide open aperture value of the master lens x magnification of the lens converter.

2) Better to know
Tele converters can provide plenty of advantages but, like other optical add-on accessories, tends to:
- Shallow the depth of field
