Pentax Q review

A tiny, but robust 12MP camera with interchangeable lenses

These graphs were produced using data generated by DXO Analyzer.

We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software.

Signal to noise ratio

A high signal to noise ratio (SNR) indicates a cleaner and better quality image.

Pentax Q: JPEG signal to noise ratio

Pentax q jpeg snr

Although the signal to noise ratio of the Pentax Q JPEG images is a little lower between ISO 200 and ISO 800, it is generally on a par with that from the Canon Powershot G12 and Panasonic Lumix GF3

There is little to separate the Q's results from the GF3 and Sony NEX-C3 from ISO 1600 and above.

Pentax Q: Raw file signal to noise ratio

Raw images from the Pentax Q compare well with those from the Canon Powershot G12. The Panasonic Lumix GF3 performs a little better up to around ISO 1600, from which point the Q has a higher signal to noise ratio.

Pentax Q: JPEG Dynamic range

This chart indicates that the Pentax Q's JPEGs have a at least a 1EV higher dynamic range than the Panasonic Lumix GF3 and compare well with the Canon Powershot G12. The Sony NEX-C3 rules the roost though.

This chart indicates that the Pentax Q's raw files have at least a 1EV higher dynamic range than the Panasonic Lumix GF3 and Canon Powershot G12, and are a pretty close match for the files from the Sony NEX-C3.

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.
