Quick MTF is high-performance software designed for measuring the most important image quality factors. Whenever you are buying a new lens, a camera, or a scanner, Quick MTF can help you make an informed decision. All you need for assessing a device's quality parameters is a picture of a simple object (see the Testing procedure) taken with that device.

Why should you use Quick MTF?

• You can save all the time that you would otherwise spend on reading multiple reviews and user opinions.
• As different samples of the same device model usually have somewhat different parameters, sometimes you have to check a few devices to select exactly what you need. Quick MTF lets you do that much more quickly and easily.
• Image quality strongly depends on such factors as the shooting mode, the distance from the image center, the additional equipment used, and so on. Quick MTF can help you find out how exactly those factors affect the image quality.
• The method implemented in Quick MTF is based on the ISO 12233 standard, so that you can test (as many Quick MTF users already do) not only camera lenses but also other imaging equipment, such as scanners, night vision systems, medical imaging devices, microscopes, and so on.

Quick MTF measures:

• Resolution, including spatial frequency response (SFR), also known as modulation transfer function (MTF); edge spread function (ESF); and line spread function (LSF).
• Chromatic aberration (CA), including area CA in pixels, CA as a percentage of the image height, and CA as a percentage of the distance from the image center.
• Color noise as variance of high-frequency noise component in shadows and highlights.

Quick MTF uses the slanted-edge measurement technique for discrete sampled systems, described in ISO 12233. You can view the measurements in graphical and numerical form, and you can export them into the Excel XML and HTML formats.

Quick MTF combines an intuitive user interface and a powerful, high-precision computing engine. It is an all-in-one solution, so you needn't install any external components or libraries.

The evaluation version of Quick MTF lets you analyze up to 50 edge profiles. Even after the evaluation period is over, you can use Quick MTF to view and analyze your old measurements (see Save and Open Workspace).

All updates and upgrades (except major ones, such as an update from version 1.x to 2.x) can be downloaded for free.

System requirements: Win2000/XP/Vista/XP64/Vista64/Windows7/Linux(Wine), 2.7Mb disk space for installation.
