Sample Images

Sensor: 1/3" Aptina MT9V024

In the image below the sugar cube was 346mm from the lens. This is the minimum distance that this lens will focus.

The sugar cube measures 16mm x 14mm.

In this next sample image the penny (d=20.3mm) was at a distance of 45cm from the lens.
This lens has a very large focal legnth and minimal distortion.

In these sample images the sensor used was a 1/4" Sony ICX618. The first image is focused at a distance of 218mm from the lens and the second at 234mm. This lens has a medium f number of f4.0 creating a reasonable depth of field while still allowing a good amount of light to reach the sensor.
