The SL will have it's own native lens but it can take on other Leica mount lenses with adapters. With the 24-90mm f/2.8-4 on, it's a pretty hefty 1.987kg (Body 847gm and lens 1,140gm) and for me personally, carrying it for a while and shooting with it, I know it's not for me. I'm probably in the camp waiting for the next M, dreaming of the ultimate digital rangefinder with in body evf so you can rangefinder focus and evf focus (with peaking and magnification). the SL from a cost standpoint, is lower priced than the medium format S system and is slightly smaller and lighter so comments of it being a S lite kinda sounds right. It comes in at S$17,850k [Body at S$11k and lens at S$6,850] with the native 24-90mm.
- Native L Mount Lens Line Up: Vario-Elmarit 24-90mm f/2.8-4 ASPH for now but 50mm Summilux f/1.4 ASPH and 90-280mm f/2.8-4 APO to follow in 2016
- T lenses can be mounted without adapter but will come with a crop factor [i believe 1.5x]
- Other lens via available adapters but no AF and IS: M, R, S and cine lenses (PL adapter).

we got to have a feel of it for ourselves
