Summary: In my Book It gets 5 stars all around , It up there too with the my Kenko 1/4 Tele converter from the first time I use it. It was awesome , I love having options available to me when I'm traveling and shooting Pix , I like to travel light and shoot a wide range of subjects , from close ups micro lens and Tele zoom and wide . Adding a tele converter doubles my options from near and far. This Teleplus pro 300 Dgx is right on for me.
Summary: Excellent Teleconverter, its pretty cheap with extra-good quality, compared to other more expensive brands, designed to be best for use with longer telephoto lenses. When using with over 100mm lenses, it improves the resolution at the peripheral corners skipping deterioration of light. On Canon EOS it works very good. If not using short lenses as 50mm or 28mm the AF works properly.
