>>4150210If you want one excellent prime to walk around with all day and it turns out 23 mm is your focal length, then get the f/1.4
If you like to change from time to time and bring along other options like the 50 mm f/2, then I'd take the f/2
>>4150219I got the 18 mm f/1.4 and was more than happy with it (until it stopped working and had to send it in for repair) but I can see where you're coming from
Sony doesn't have clinically perfect lenses for APS-C though
