>>3780556>An a7iii with a 35mm f/2.8 is exceedingly tiny.It doesn't allow you to snap from a distance with usable results though.
Also you can go even smaller if you go with the Samyang AF 35mm f/2.8 FE.
Here's the equivalent 90D setup with the EF-S 24mm f/2.8 STM. Gets the advantage of a deeper DoF, something usually desirable in street photography. Not all that much bulkier than the Sony.
