50 1.2 is with me anywhere i go! To me it is the perfect walkaround lens.
I have the 35 1.4 also but if i had to choose i would take the 50 everytime.
As you know anything below 50mm will create a bigger sense of space and most of the time i dont like the look.
And the 50 is a much better portrait lens.
To me the 50 is wide enough for a walkaround lens even with 1D IV 1.3 crop.
50 is weather sealed, the 35 is not.
I mostly use focal lenghts of 50&85 and for variety and special occasions i have tse 24, 35 and 135, but most the time the 50 is on my camera.
