I just wanted to share my experience with the SL so far:
For someone owning various Leica lenses from other systems (M, T, S) it is really nice to be able to combine those on one body.
It seems to achieve pretty good focus accurancy with the M lenses on the SL without using magnification, pretty good means nearly nail focus but not 100% nail focus.
I still hope and wish there will also come some smaller a littler slower AF lenses. Like the 1.8 series from Nikon for example.
I do like the 24-90 when shooting outside, but for indoor family shooting it is too big for my taste.
A 35/2.0 and a 50/2.0 would be great.
And also a 70-200/4.0 smaller than the 90-280 would be great for my taste. Or a 180/2.8 prime.
It is ok to use the SL with M lenses and its also ok to use it with T lenses, but in the end I would like to take advantage of that fast AF when owning a body (SL) that can do it. Overall the build, viewfinder and handling of the camera is fun to use.
