Some LTM and M Voigtlander lenses have the same formula. Those include the 12/5.6, 15/4.5, 21/4, 25/4, 35/2.5, 50/1.5, 50/2 LTM versions and the first versions of their M counterparts.
Some lenses were made in LTM only: 28/1.9, 28/1.9, 50/2.5, 50/3.5, 75/2.5, 90/3.5
Although they have their big fans today, all of these were discontinued due to relatively poor sales.
One was made in both LTM and M, both with completely different optical formulas: 35/1.7.
Some were made in M only: 35/1.4, 40/1.4
Recent M only versions have improved optical designs for digital sensors: 10/5.6 (not released yet), 12/5.6 III (not released yet), 15/4.5 III, 21/1.8 (M only), 35/1.2 (M only), 35/1.7 M (completely different optical formula compared to the LTM version).
