All teleconverters degrade the image to some extent, 2x more than 1.4x. In film & 6Mp days cropping wasn't really an option so they did give more reach without the expense of a longer lens. Long ago I had an M42 Vivitar 2x which made my SuperTak 55/2 a useful 110/4. Given a high quality TC and a fast host lens, good results are possible. However with the high Mp sensors now in common use, a cropped image without the TC may be just as good or even better so what is the point? Only perhaps cropping options of the TC image which starts with full Mp?
