Nah, no need to order, 'cause I already have. The reviews on this one (not above) have been pretty depressing. That said, of course, it's not for most with no manual shutter, no viewfinder, no flippy screen, and not video focused (as someone who makes a living in video, hybrid video specs discussions are the worst) or an "only body". I'm already in the M/L-mount space so worth a try. With them reportedly only milling 7-9 a day, if interested best to jump now and pull out later. We'll see, especially on that electronic shutter. My experiences have been poor, though with older and larger size/slower readout sensors. I'm curious how many will be released before they kill the model. Sony/Nikon/Canon are probably not under threat. And yes, I almost bought a Leica TL2 at one point too.
Sigma is my favorite failed cameras company (still have two Foveons).
