had as one of my first a 50mm fixed focal length and was already excited for indoor photography without flash. Through a good telephoto, I have that 50's no longer so often had it, but because it is often too close. 35mm is perfect and the little less light intensity (the 50 is a 1.4) can be more than verknusten with today's jumps in the software sector. Very strong buy recommendation, not only for purists.
