Ok, I realize that's a wide open question and the answer is "it depends" but just looking to generate some thoughts for myself. My normal lens for this has been the Z 24-70/f4 which came with my Z7II but that was mostly supplanted by the 24-120/f4 unless weight was really important. However…at f4 neither of these is really good for street photography or low light or situations where shallow DoF is a nice thing to have. So…I'm considering adding a faster prime for this sort of situation. While f1.2 is better than f1.4 for DoF issues…the weight and size for me make the extra 1/3 of a stop not worth it. So…thinking of either the 35/1.4 or 50/1.4…and wondered which would be more useful for this sort of single lens/body walk around I'm OK with foot zooming if needed use. One thing I am going to do is try a couple outings and shoot just at 35 and 50 to see what seems to suit better but wondered what others might have concluded.
