Hi, I’m somewhat new-ish to photography and looking to expand to doing newborn photography. I currently have a 50mm Sigma Art lens for my Canon 5D mark iv. My question is this: if I were to invest in a 100mm Macro Canon L series lens to take photos of tiny newborn feet (for example), not the whole newborn baby, would I get better quality or more tack sharp images vs the 50mm sigma for these specific shots? My photos are done in a studio if it matters.
Thanks everyone for your advice!
