Hi,

Can you fill me in? When Sigma made their own camera bodies, was it a legal issue they did not choose to use existing mounts such as Canon and Nikon?

SA mounts lens are not exactly cheap and you are stuck with this mount. Would they have not sold more camera bodies using a Canon or Nikon mount?
So why are they making their new lens in Leica mount?

So their trend is to continue to make lenses with other mounts and ditch Sigma mount for future bodies?

Their lens conversion service is great but price is too steep.

Used Sigma 17-50mm going around $220-240. Sigma mount, no used, retail $369. So you end up paying more for pretty much same thing. Not very motivating. No incentive to buy Sigma other than their sensor.

Almost $400 for dedicated TTL flash and not even available?I’m sticking to manual flash, no choice anyway. I’m just scratching my head.

"Mechanically, the (inner) SA-mount is similar to the Pentax K-mount as well,[2] but with a flange focal distance of 44.00 mm, identical to that of the Canon EF-mount. Like the EF-mount, the SA-mount uses electrical communication between body and lens, and in fact uses the same signalling lines and protocol as the EF-mount, despite the physical incompatibility."
