Canon EOS-1Ds Mark II Review
Resolution Chart Comparison
Shots here are of the PIMA/ISO 12233 standard resolution test chart (more of which are available in our comparison database). This resolution chart allows us to measure the actual performance of the lens and sensor system. Studio light (continuous), cameras set to auto, all settings factory default. Aperture selected for optimum sharpness. Exposure compensation +0.7 EV to +1.3 EV.
Beyond our chart, but not beyond our means
The standard PIMA/ISO resolution chart is capable of measuring the resolution of standard Bayer sensor digital cameras up to approximately ten megapixels, beyond that we must be a little more creative. To compare the resolution of the D2X and EOS-1Ds Mark II we shoot the resolution chart from twice the normal distance and end up with a chart exactly half it's normal size. This allows us to measure resolution up to 4000 LPH. When reading the crops below values on the chart now represent 1/200 lines per picture height. So a value of 15 equates to 3000 lines per picture height. It's worth noting that the EOS-1Ds Mark II resolution chart was shot with a sharpening setting of 0 (default).

Crops from half-size chart (double distance)
Important: the crops below are taken from a standard resolution chart shot from twice the standard distance, hence measured resolution is double that indicated (10= 2000 LPH).

Measurable findings (three measurements taken for each camera):
|Canon EOS-1Ds Mark II||Horiz LPH||2800||3000|
|Nikon D2X||Horiz LPH||2400||2800|
|Kodak DCS Pro SLR/c||Horiz LPH||2400||* 2700|
|Vert LPH||2200||* 2700|
|Canon EOS 20D||Horiz LPH||1850||2000|
|*||Moiré is visible|
|LPH||Lines per Picture Height (to allow for different aspect ratios the measurement is the same for horizontal and vertical)|
|Absolute res.||Point at which all lines of a resolution bar are still visible and defined, beyond this resolution loss of detail occurs (below Nyquist frequency).|
|Extinction res.||Detail beyond camera's definition (becomes aliased)|
|n/a||Not Available (above the capability of the test chart)|
|n/v||Not Visible (not visible on test results)|
* Nyquist frequency defined as the
highest spatial frequency where the sensor can
still faithfully record image detail. Beyond the Nyquist frequency aliasing occurs
As we had expected the EOS-1Ds Mark II delivered the highest resolution we've measured on our charts to date. It delivers 50% more horizontal resolution than the EOS 20D and 16% more horizontal resolution than the Nikon D2X. These values are almost exactly the same as the difference in pixel count.
