I'm starting to use the digital teleconverter on my E-P5; mainly with my 35-100 f/2.8 so it gives me a 70-200 f/2.8 equivalent I think at 2x and I set it up so I can access it with a press of a function button. I like it the flexibility of it when shooting sports, because I can quickly switch between 1x and 2x. How does this work in regards to image quality and what level of pixels am I looking at quantity wise? 16MP or less? Any help on this would be greatly appreciated!
