I am interested in picking up this lens or a used EF 100mm macro, because I have a baby on the way in the fall and would like to be able to take some newborn detail shots (fingers, toes, ears, etc). I'm assuming 1:2 will be enough for that purpose, but I have no experience with macro photography. Can anyone enlighten me if a 1:2 lens would be limiting for this purpose? Hopefully, I'll also be able to hire a newborn photographer, but with COVID, not sure that will be a viable option right away, so I'm looking to get prepared.
