>>3772955>Can you use a teleconverter to adapt a crop lens to full frame?thats actually an interesting question unlike most itt. i unfortunately only have a single crop lens, the Sigma 18-35, and unfortunately the 1.4X TC isnt compatible with it, as it protrudes in to the lens a little bit, and the 18-35 has a element at the very rear. instead have a sigma 14mm f/1.8 with a 0.7 speed booster.
