I want to get one of these 3 lenses for the future on a portable setup, either pair with my Canon DSLR or my Player One OSC ideally shoot wide open. I am currently using a Canon 200mm F/2,8 L II but its too close of a FOV to my Esprit 100 so im trying to get rid of it and get one of these 3.
My current top pick is the 40mm just because its so versatile in terms of the wide focal lenght can be used for MW mosaics (https://www.astrobin.com/h4h5ws/) and untracked work in case of traveling (and overall its the sharpest of the bunch wide open), the 105 is a nice focal lenght and its big, tough to do untracked with it in case of travel (downside from other images it needs to be stopped down a stop or 2 which imo defeats the whole purpose in getting a 1,4 lens for that price if I need to stop it down to 2,8 for it to be sharp) (https://www.astrobin.com/v2noq8/?q=sigma%20105), finally the 135 is sharp (not as sharp as the 40) but a nice variation to the bunch (worst for MW untracked but could be best overall also probably needs a stop down to work best) .
