Lenses 35/21 Gears 46/20
What about 15, 21, 24 and 28mm? Not so many moons ago, zoom lenses had a bad reputation but lens technology has evolved. I now often use a Fuji 2.8/16-55mm lens and it gives me whatever wide-angle option I fancy for whatever moment.
16*1.5=24.
I'm happy with 20mm 3.8 under 100$ Vivitar F mount lens. Planning to get LTM adapter for it. I also have two 28mm F mount lenses. My two Nikon SLRs kit is 50 free. I'm not considering 35mm for it at this moment.
But on Leica 35mm is my main choice.
