Pentax Q review

A tiny, but robust 12MP camera with interchangeable lenses

As part of our image quality testing for the Pentax Q, we've shot our resolution chart.

If you view our crops of the resolution chart's central section at 100% (or Actual Pixels) you will see that, for example, at ISO 125 the Pentax Q is capable of resolving up to around 22 (line widths per picture height x100) in its highest quality JPEG files.

Examining images of the chart taken at each sensitivity setting reveals the following resolution scores in line widths per picture height x100:

Marketing Information

The Pentax Q features the newly developed Q mount, with a mount diameter shortened to approximately two-thirds of that of the conventional K mount. This was made possible by reducing the flange back (the distance from the lens mount surface to the image sensor surface) to nearly one-fifth of that of the K mount, as well as by optimizing the size of image circle of its lenses to be proportioned to the size of the compact image sensor. The Q mount system also eliminates an optical finder, mirror box, focusing plate and AF sensor, making the Pentax Q's body the smallest and lightest in its class. The body has been made of magnesium-alloy, which gives an elegant, high-quality texture to the compact, lightweight camera body while improving its durability.
