Former m43 shooter - this is my ultra-compact EDC kit
X-E4 with the 13-33mm that I use for landscapes
SG-Image 25mm f1.8 pancake and TT Artisan 35mm II.
Have my eye out for the 7 Artisan 18mm f2, and also maybe a Viltrox 75mm f1.8 EVO
I love the X-E4 for how light it is, only 360g, plus all these small lenses, even m43 equivalents would be larger!
