Reading the spec. sheet for the Leica SL, it seems clear that these three options are available. Using up to +/- EV 3 stops.
Having now twice handled this camera with the 24 - 90 mm lens, I can only see an option for 3 / 5 frames.
Has something changed with V-2 update ? Both cameras had this firmware installed.
Many thanks.
p.s. Did a search but no information found.
