Review
1．Overview
The 04 Toy Wide Lens for the Pentax Q has a focal length of 6.3mm, equivalent to a 35mm wide-angle lens for the Q and Q10, and 33mm for the Q7 and Q-S1.
The 35mm equivalent values for the Q7 and Q-S1 differ from those calculated based on the sensor size, but this lens was released during the Q era and its image circle does not cover a 1/1.7 sensor, so it is cropped to a usable area on the camera. Raw images generated by the Q10 are 12 megapixels at 4000×3000, while raw images generated by the Q7 are cropped to a resolution of 3629×2722, approximately 10% smaller. However, JPG images from the Q7 are saved at 4000×3000, confirming that the resolution is compensated for by in-camera image processing.
The Unique Lens was released to supplement a company’s limited lens lineup and is designed to be affordable. This lens is no exception, with a simple design, including a plastic mount, a fixed F7.1 aperture, and no mechanical shutter, but the lens configuration is three groups and four elements, so it is thought to be an advanced version of a triplet with a Tessar configuration.
2．Usability
Like the other three unique lenses, the 04 Toy Lens Wide for Pentax Q has near and far focus positions, with the far position being over-infinity rather than infinity.
If you’re shooting landscapes and thinking that far focus is fine, shooting at the far position will result in a blurry photo.
At f/7.1, it’s not narrow enough to be called pan focus, so you need to focus on the intended subject. Despite its relaxed lens concept, this lens is somewhat contradictory in that it requires precise focusing.
When the focus is properly achieved, it produces a reasonably sharp image.
This lens also does not perform any internal processing when capturing JPGs, recording uncorrected images in both Raw and JPG.
Because the Pentax Q series does not have a mechanical shutter, this and other unique lenses in the series use the sensor’s shutter.
3．Summary
In conclusion, to sum up the 04 Toy Lens Wide for Pentax Q, it is a relatively inexpensive lens among the Toy Lens series as of 2025, and it is worth purchasing for the list price of around 5,000 yen.
