I use a Leica SL3 for most of my architecture work and when travelling, and I am considering a smaller L-mount body for city walks. The Sigma BF interests me for its design and build quality, but I have read mixed opinions about the handling without a grip or viewfinder.
Has anyone here used one for a longer period, ideally alongside an SL body? I am mainly interested in how it feels after a full day, not the specifications.
