Imatest™ is the digital imaging industry's leading software package for measuring key image quality factors using inexpensive, widely-available targets.more...
...Measure device sharpness (MTF), perceptual sharpness (SQF), color response, noise, dynamic range, tonal response, lens flare (veiling glare), lens distortion, lens vignetting, sensor nonuniformity, and color moir with SFR, Colorcheck, Multicharts, Stepchart, Distortion, Light Falloff (Uniformity), and Rescharts.
Here are the Imatest Results for the Canon EOS 40D.

Understanding Sharpness (MTF) charts.
Imatest has been selected to perform certain contrast analysis (such as MTF and SQF) for the LCD MTF measurement system.
The original system is composed (R-to-L in the picture to the left) of a Canon EOS D30 Digital SLR camera, a Leica Z6 APO long-distance microscope zoom lens, an iris diaphragm to control the field of view, and an in-line integrating sphere with a 3-watt lamp as a uniform light source - all horizontally mounted on a vibration-free optics table.
