I’m also thinking of using the 75. My camera is not pocketable so it needs to be bagged anyway. It’s certainly an interesting focal length to use for a month.Actually, I might go m43. Must be over a year since I've used it (donated to my son who refuses to take the PL20mm off it). If I use the Oly 75mm F1.8, then it won't be too hard to get something of a certain quality each day.
