Canon have released their best mirrorless yet, we now have very good bodies from Leica, Sony, Panasonic, Fuji, Olympus and Canon are slowly getting there. Note a major manufacture missing, yep Nikon, come on Nikon get your act together.
If I had no cameras at all then I would likely buy the Leica S for my medium format solution, Leica M for my full frame mirrorless and I am hoping that the new Leica TL will be a cropped sensor sensation. If I had to buy a mirrorless now it would be between Panasonic and Olympus.
On the Leica front we have rumours of a new zoom for the SL and new primes bringing the range to 35mm, 50mm, 75mm and 90mm so a good range of primes and zooms of 16-35mm, 24-90mm and 90-280mm. With adapters for Nikon and Canon SLR cameras plus the ability to shoot with any Leica lens made its now quite a system.
