Alex Barrera's comparo of the SImera 50mm and the 2023 Summilux CF below (which gained a 0.45m MFD and 11 aperture blades over the older version). It's hard to know the habits of others using fast lenses, but I very frequently use a 50mm at f2-f2.8-f3.5 so the aperture blade count and behaviour is very important to my photography. Alex shows the apertre shapes of the Simera 50/1.4 at 2:00 and the Summilux at 3:05.
