A Camera for the Hard-Working Professional

Camera memos: image management made easy

Use the camera or a PC to create written or voice memos that can later be added to photos. Memos can contain up to 30 seconds of audio or up to 100 items with descriptions of up to 128 characters each.

Putting survey slates to good use with image clips

A previously-recorded image of a survey slate can be embedded as sub-image to a photo of the entire worksite, making it easier to take photos when your hands are too full, or the location too cramped or too dark, to place a slate. You can also choose the slate’s size (large, medium, or small) and location (up, down, left, or right).

Compare images with “Watermark Options”

Use existing pictures as a template when composing new photos. Template transparency can be selected from 20, 40, 60, and 80 percent. Templates can also be placed next to photos with the same composition for side-by-side comparisons. One way in which this feature can be used is for before and after shots on construction sites.

Adjustable six-LED Ring Light

Ring LightThe lens is surrounded by a six-LED Ring Light. You can choose which LEDs light and adjust their brightness to get clear shots showing fine details such as the model numbers on small parts or scratches in walls or floors.

Equipped with GPS and an electronic compass

Use the camera’s built-in GPS and electronic compass to record location data with photos and movies. Location data can be acquired via GPS, the Japanese Quasi-Zenith Satellite System (QZSS, also known as Michibiki), and GLONASS. The “GPS Lock” button can be used to record the location of a selected target.

4K resolution for sharper movies

Shoot movies in 4K (frame size 3840 × 2160 pixels, 30 fps) for high-resolution footage that gives you an overall view of a big construction site, for example, or helps you grasp the relative positions of various objects.

Internal memory with around 6.5 GB of image storage

The camera features internal memory with space enough for 856 maximum-quality images. Keep shooting secure in the knowledge that won’t run out of storage when the memory card is full.

Password protection restricts access to a variety of camera functions

Password-protect access to any or all camera features, including camera controls, menus access, internal memory viewing, and USB connection. Choose separate administrator and user passwords for greater control over security. Access can be granted by scanning a password barcode or entering the password using the camera’s onscreen keyboard.
