Imatest is shaping up to be an interesting development for the photographer who likes to know everything about their equipment. It is a suite of programs for testing the sharpness and image quality of lenses, digital cameras, and digitized film images using inexpensive, widely available targets. Imatest has now been released - you can now download an evaluation version that allows up to 20 runs of the individual modules (SFR, Colorcheck, or Q-13). Online purchase and registration is available. The introductory price is $59 US.

“With Imatest you can:
 
- test lens performance at different focal lengths and apertures to learn where each lens works best; 
- examine the effects of camera and post-processing settings, such as mirror lock, ISO speed, white balance, RAW converter, and sharpening; 
- compare the performance of different cameras, even if they have different amounts of built-in sharpening; 
- compare your camera and lenses with results derived from websites such as imaging-resource.com, dpreview.com and others. This is important because quality control is far from perfect. Even premium lenses from reputable manufacturers may fail to meet expectations. With Imatest you can find out fast and return them if they are substandard. “
