I figured it would look like 5dm3 images, im glad to see that it really is. Could be a good lowlight sidekick if you can get past the sd card among other things.
Just noticed a serial number middle right directly above the sigma name. For an "Art Series lens that looks this good it seems odd to put it there.
The "Art" lineup is also based on focal lengths used for art and portraiture, most likely always Prime Lenses, 35/50/85/135Sports being fast/ weatherproofed/long focal lengthscontemporary line...
I don't think it is given it is an art series not a sports series. If it does that will mean several more buyers i would think.
