The E O S-1Ds Mark III is the seventh Canon professional E O S-1D seriesdigital SLR, although only the third of the 's' suffix sub-categorywhich indicates a full frame sensor. Three years since the lastE O S-1Ds, the Mark II, the Mark III pushes digital SLR resolution overthe twenty megapixel barrier with specifically twenty-one-point-onemillion pixels (5616 x 3744) on its 36 x 24 mm (full 35 mm frame)sensor. Canon also claims to have increased the 'light gatheringefficiency' of the sensor by reducing the amount of (wasted) spacebetween micro lenses, hence despite the resolution increase the MarkIII still provides sensitivity up to ISO 3200 (with boost enabled).
