I am soon to buy a fast prime for my OM-D and have narrowed my choice to the Pany 25mm/1.4 and 20mm/1.7. Forgetting all the other nuances of choosing between the two, I am now at the point of choosing based upon the FOV. I have shot with my kit lens (12-50) at the 2 focal lengths but still cannot make up my mind. I probably lean towards 25mm for outdoors but am uncertain which I like better indoors. I am curious as to why others prefer on FOV over the other.
