A small underwater subject can make a camera’s close-up mode sound like the only specification that matters. The TG-7 provides a useful reason to slow down: its microscope menu contains several different workflows, and none changes the camera’s water-protection conditions.
The current October 22, 2026 version of a TG-series guide revisits settings for the TG-7, TG-6 and TG-5. Treat this as updated discussion of established models, then consult the documentation for your own camera. It is not a new-camera announcement.
One close-up label covers several outputs
The TG-7 instruction manual separates Microscope, Focus Stacking, Focus Bracketing and Microscope Control. It describes close focusing from 1 cm in the microscope group. These functions do not all produce the same kind of photograph.
In Focus Stacking, the camera takes images at different focus positions and can combine them into a composite. The manual says it records the first frame and the combined image, and warns that camera movement may prevent a successful composite. Focus Bracketing records a sequence with changing focus positions. Microscope Control instead provides a magnified monitor view, with a warning about graininess at high magnification.
For a buyer, the useful distinction is the result you want to take home. A single frame, a camera-generated composite and a sequence for later work are separate choices. Ask to see the files associated with the feature instead of judging it only from a bright enlarged preview on the rear screen.
Water protection belongs on another line
The manufacturer’s TG-7 specifications list 15 m water resistance under the stated conditions. The manual explains the testing basis and the precautions for underwater use. A photographic mode is not an extension of that rating, and an accessory needs its own matching documentation.
Keep three things together when planning a camera setup: the exact camera, any housing or other accessory, and the instructions that apply to their combination. A review covering several generations is helpful context, but it should not quietly replace the current manual for the item you own.
Decide what the close-up is meant to show
Before buying more equipment, consider whether your goal is a shareable picture, a detailed record or a series you intend to process later. That answer helps determine which output matters and which questions to ask about the workflow. It also avoids treating a composite image as if it were necessarily a single exposure.
Our underwater technology checklist starts with matching a feature to the actual hardware and evidence. For close-up imaging, record the camera model, shooting method and water-protection conditions behind the picture.
Dates and scope: Current guide version: October 22, 2026; both its publication and modification metadata use that date, without establishing the page’s earliest history. Manufacturer specifications and the undated TG-7 manual checked October 25. TRIMIX has not tested these modes or measured underwater image quality.
