>>387358016-80 f/4 which I enjoy the versatility of but have a hard time taking nice shots with. F/4 is very slow for a minimum aperture. 6 stops of OIS is helpful too, but it's no replacement for a wide aperture obviously.
I also have the 35mm f/1.4 which is fun to use and versatile, but limiting for landscapes.
And recently I got samyang's 12mm f/2 which I used for a couple of shots ITT. it has no electronics so the exif will show as f/1.0 I think.
I didn't intend for that pedestrian to be in my photo, but there she was when I took it. My main objective was to walk that evening, so I wasn't patient.
