Hello, I have a Canon T6i and I am looking to buy a new lens, I am mostly interested in product photography, sharpness and image quality is super important to me. I am currently using a kit lens which is Canon EFS 18-135mm and I am thinking about buying Sigma 24-105mm f/4 DG OS HSM Art and it's very expensive so I need to get some advice from an expert before buying it. Is it worth it or not? Am I ganna see a big difference in the quality? What is your advice to me?
