Posted this on another forum too but some thoughts on the lens.

Great for crop sensor users if you want a versatile portrait zoom.
You can essentially get the equivalent images to a FF and 70-200mm f2.8 zoom combo but there's very little weight saving if any and you give up lens stabilisation and some reach.
I can only speculate whether the addition of stabilisation may affect the lens design to adversely affect the bokeh characteristics. Ironically the only mounts that this lens is currently offered in doesn't have sensor based stabilisation.

On the up side, the combo should come in much cheaper than the FF counterparts. You also get close to complete AF frame coverage on crop sensors and the f1.8 aperture will enable the AF to work longer as you approach the lower limits of the AF EV working range.
It also remains to be seen what the actual image circle produced covers. The Sigma 18-35/1.8 is almost usable at 35mm on a FF sensors. Its possible that the 50-100/1.8 could be quite usable at some of its focal lengths with a modest crop or change of aspect ratio and not just a 1.5X crop.
Which raises the question, could one consider this crop zoom lens for a FF camera?
The D810 already has a very usable 16MP in DX crop and its successor might well have over 50MP producing a 20+MP DX crops, equalling the Nikon D500. So if much of the lens work with an APS-H crop for example, you could have something similar to a 65-130 f2.3 on FF.
Lots of questions to be answered.
But well done, Sigma.
 

I was hoping that Sigma will put Optical Stabilisation in this lens.
Gotta wait for the reviews on this non OS lens.... :D
 

Now available!! Just Saw MS Color fb post!!
