I would advice to get 1.4 first, for not to regret of a slower aperture of the 35/2. And then after some time to get 35/2 and compare your feelings. For me, I prefer 35/2 because of its bokeh tracery first. 35/1.4 has a nervous, little suicidal bokeh (for my eye), and 35/2 has a joy, festive bokeh. Other advantages are AF speed, better retro-look, WR, light eight and significally smaller size. That's it
