I was wondering if anyone has attached a teleconverter on their 500mm? Im looking at the Sigma 150-500mm, in the product description it reads:
- Can be used with optional Sigma 1.4X EX DG APO or 2X EX DG APO teleconverters to produce a 210-700mm F6.3-8 manual focus ultra telephoto zoom lens or a 300-1000mm manual focus ultra telephoto zoom lens respectively
- My question, is the image quality still the same or does it lower the quality of your image by adding a teleconverter?
