I dont know about the 60mm macro as it is an EFs lens so I have no interest in it, as it is usless for FF or film bodies

The 16-35mm hoever is an L lens and has excllent optics

More recent Sigma lenses have very good optics, especially the DX range like any lens make the more ££/$$ the better the optic generally. (with a few exceptions)

They wouldn’t have made the cane if you weren’t meant to break the rules
