The Pioneer DJM-850 mixer follows up on the DJM-800 and is targetted at the semi-pro or mobile DJ, it inherits a lot of the DJM-800 like the basic layout, BPM synced effects and the Filters (Color FX).

In Silver : Pioneer DJ DJM-850-S
In White : Pioneer DJ DJM-850-W

The biggest differences are the addition of Reverb, Spiral and Slip Roll (same as on DJM-900nxs) to the BPM Effects, slghtly modified Level/Depth rotary, 4 soundcards with DVS (and Traktor) support, and all new Beat Color FX. In fact the DJM-850 combines the most appriciated features of the DJM-800 and has the same footprint, but has in addition to that the same build quality as a DJM-900 and adds some new effects/filters.
