I have been testing the Olympus Digital teleconverter lately. It can double your focal length on your M.Zuiko lens. That why it is very tempting. Wouldn’ t it be great to have extra reach on you trips if travelling only with one lens?
But since it is a digital teleconvetert, it will upscale the cropped image you see from the EVF or the LCD. How bad is the loss in image quality?
Check out this video and the images below to see for yourself.
As you can see the difference is not big, but the upscaled raw-filer is a bit better.
