I enjoy street photography and, when with them, shooting my grandsons sporting events so I thought a 70-200 would be my next lens. However, since I am shooting more street photo's I changed my plan. I wanted to move to a manual 35 mm lens so I started looking at the Loxia 35. Clearly, the Loxia lenses are excellent but very expensive. So, I started looking at alternatives and found the Voigtlander Nokton Classic 35mm f/1.4 Lens for Sony E-Mount (Voigtlander 35mm f/1.4). I've read several threads here and on Fred Miranda about the Voightlander 40 mm that seem to focus on the M mount. Should I choose a lens with an M mount that means I need an adaptor. From what I read, even with the adaptor, the M mount lens would be smaller and lighter on my A 7 II. What I don't understand is why selecting the M mount and adaptor would be more advantageous than going with the E mount version. My skills and knowledge are well below many on this site so I would value thoughts on purchasing this lens vs purchasing the M mount with adaptor version. Thanks in advance to all that reply.
