Regular readers know that I've looked at a lot of mirrorless cameras, always looking to see if this is a space to expand into.  I've liked many of them, and hoped for more from others.  I guess I'm already a mirrorless user, as I've been shooting Leicas for many years, starting with film, then a substantial gap in time to the M9 and now the M (240).  They are wonderful cameras but different from the "standard" mirrorless in that they are manual focus rangefinders.  The SL however, is something very different indeed.
