I recently picked up the sigma 50mm f1.4 art lens for my Sony a 7iii. I must say the lens is great and sharp. I have a line up of 17-28mm and 70-180mm from tamron but I was missing everything in the middle. I was just browsing through Amazon and notice that sigma have a 24-70mm for E-mount lens. What should I do in this case? Return the 50mm f1.4 and get the 24-70mm f2.8 instead?? I know prime lenses are design for a specific task but don’t really know what to do here. Please help me decide.
