Are you wanting a really nice high end camera? We have a recomendation for you! The Canon 1Ds Mark III is the camera for you.
The EOS-1Ds Mark III is the seventh Canon professional EOS-1D series digital SLR, although only the third of the 's' suffix sub-category which indicates a full frame sensor. Three years since the last EOS-1Ds, the Mark II, the Mark III pushes digital SLR resolution over the twenty megapixel barrier with specifically twenty-one-point-one million pixels on its 36 x 24 mm sensor. Canon also claims to have increased the 'light gathering efficiency' of the sensor by reducing the amount of (wasted) space between micro lenses, hence despite the resolution increase the Mark III still provides sensitivity up to ISO 3200.
As well as increasing resolution Canon has pushed continuous shooting up a step with five frames per second over the Mark II's four frames per second. This means that at full speed the two DIGIC III image processors are dealing with an impressive 185 MB/sec. Other improvements include the larger screen, Live View, a fourteen-bit A/D converter and fourteen-bit RAW files, UDMA Compact Flash support and a whole range of features inherited from the EOS-1D Mark III.
From a build, function and usability point of view the EOS-1Ds Mark III is identical to the EOS-1D Mark III apart from the full frame sensor, larger viewfinder and UDMA support for Compact Flash cards.
