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!

In short yes, but see if you can hire one for a day and try it out. The sharpness and focal length might make the hand/feet shots a bit too clinical, great for eyes though. You probably won't need IS if you are using flashes/strobes in a studio environment so there might be some cheaper options.

The perspective will of course change because of the focal length change, and that will affect the rendition of the background. Other than that, if you are stopping down to f/11 or 16, the sharpness will probably be about the same.

Is the quality you are getting now not satisfactory?

No, not at all unhappy with my Sigma Art 50mm. I just have 5 newborn sessions booked in the next 2 weeks, (at a discounted rate, since I’m venturing into doing newborns now, from my regular family sessions). So I’m just wondering if a 100mm is worth the investment or if the 50mm will provide almost the same quality photos.

If the 100mm will give much better quality photos for these specific shots (feet, hands, ears, etc), then I’d be happy to make the investment. But if I’d get almost the same quality with my 50mm then I won’t bother :)

You don't need a $800 USD lens to photograph a baby's feet. The lens you have will work just fine. In addition if you do decide to get into life size photography lenses in the 100mm range are a poor choice. The working distance might not be long enough for natural light work, and for flash based macro the working distance will work against you (lenses in the 60mm range are better).

Forget about absolute image sharpness as a metric for judging lenses. They are all pretty sharp, and the only one looking at your photos at 100% pixels is you...
