This is the upcoming Zenit D1 mirrorless camera *UPDATE: fake picture*
The upcoming Zenit D1 mirrorless camera will have a 42.4MP BSI CMOS sensor without AA filter with 50-25,600 ISO range. The official announcement should be in the next few days. The camera design looks very similar to the Leica SL (update: I think this is a fake - I just found the original Leica SL product picture):
Stay tuned for updates.
