That's "expanded ISO", which is pretty worthless in reality. Pentax K-5ii: Manual: 100-12800 (1, 1/2, 1/3 steps), expandable to ISO 80-51200, Bulb mode up to ISO 1600 Pentax K-3: Auto: ISO 100-51200 (1, 1/2, 1/3 steps), Auto ISO range selectable, Bulb mode: Auto ISO n/a; Manual: 100-51200 (1, 1/2, 1/3 steps) Nikon DF: ISO 100 to 12800 in steps of 1/3 EV; can also be set to approx. 0.3, 0.7 or 1 EV (ISO 50 equivalent) below ISO 100 or to approx. 0.3, 0.7, 1, 2, 3 or 4 EV (ISO 204800 equivalent) above ISO 12800;
Here's what Nikon engineers say about "expanded ISO": http://joefaraceblogs.com/expanded-iso-settings-why-i-dont-likeem/ And here is Fuji's explanation of their "extended ISO": http://www.fujirumors.com/how-to-use-extended-iso/ The manual ISO numbers are all that matter.
