Winner: Sigma 50mm f/1.2 DG DN Art Sony
Regarding weight: When it comes to the lens's weight, it's actually more important than many people think that the lens weighs as little as possible — it's simply a pain to lug around a lens that's too heavy when you're photographing or filming for several hours, and a few hundred grams can make a real difference.
Both lenses have the same minimum focusing distance and therefore one is not better than the other when it comes to how close the lens can focus.
Winner: Tied
Regarding minimum focusing distance: The lens's minimum focusing distance determines how close you can photograph your subject, such as a face or an animal. If the minimum focusing distance is 50 cm then you cannot get closer to your subject than 50 cm. Macro lenses often have a very low minimum focusing distance so that you can take close-up shots (macro photography).
