There is also the Voigtlander 40/2 Ultron SL IIs, the one styled like a 1960s Nikkor. It's not a macro lens but it does focus a lot closer than most normal lenses - down to 0.25m, giving 1:4 magnification. It has a CPU so is fully compatible with modern cameras. It's a very nice little lens.
And if you don't need the fast aperture and can live without the CPU, the Nikon AIS 55/2.8 or AI 55/3.5 are also optically superb. Both get to 1:2 without accessories.
