Overview

2. Usage Features
3. Maintenance Features

The Brinno Lens BCS 24-70 is a specialized accessory designed to enhance the capabilities of Brinno Time Lapse Cameras, particularly the TLC200 Pro. This lens allows users to capture time-lapse footage with greater flexibility in terms of focal length and aperture, providing more control over the field of view and depth of field in their recordings. It is engineered for straightforward installation and integration with compatible Brinno camera models, making it a practical addition for users looking to expand their time-lapse photography options.

Function Description

The primary function of the Brinno Lens BCS 24-70 is to serve as an interchangeable lens for Brinno Time Lapse Cameras. Unlike fixed lenses, this accessory offers a variable focal length ranging from 24mm to 70mm, enabling users to adjust the field of view from a wide angle to a more zoomed-in perspective. This versatility is crucial for various time-lapse scenarios, whether capturing expansive landscapes, construction projects, or more focused events. The lens also features an adjustable aperture, from F1.4 to F2.4, which allows for control over the amount of light entering the camera and the depth of field. A wider aperture (smaller f-number) is beneficial in low-light conditions and for creating a shallow depth of field, blurring the background and emphasizing the subject. Conversely, a narrower aperture (larger f-number) increases the depth of field, keeping more of the scene in focus.

The lens is designed with a focus adjustment mechanism, allowing users to manually fine-tune the focus to ensure sharp images of their intended subject. This manual focus capability is essential for achieving precise clarity, especially when dealing with subjects at varying distances or when specific elements within the scene need to be highlighted. The lens's construction includes a top cover and a bottom cover, which protect the optical elements when not in use or during storage. It also incorporates a zoom ring and an aperture ring, providing tactile control over these critical settings.

An integral part of the lens system is the IR Filter, which is specifically designed to work with the BCS 24-70, as well as other Brinno lenses like the BCS 019 and BCS 18-55. The IR Filter is crucial for optimizing image quality, particularly in outdoor or varying light conditions, by filtering out infrared light that can sometimes interfere with color accuracy and image clarity. Its recommended continuous use with the lens underscores its importance in maintaining consistent image performance.

Usage Features

Installing the Brinno Lens BCS 24-70 on a compatible Brinno Time Lapse Camera, such as the TLC200 Pro, is a user-friendly process. The installation begins with removing any existing lens kit, like the BCS 019, by rotating it counter-clockwise to unlock it. It is advised to turn the camera face down during this step to prevent dust from entering the sensor. Once the old lens is removed, the BCS 24-70 can be installed by removing its bottom lens cover and turning it clockwise onto the camera body until it is securely in place. Users are cautioned to handle the camera carefully, especially when using different lenses, as the shift in gravity center, particularly without batteries, might cause the camera to tip over.

The installation of the IR Filter is also straightforward. After rotating the lens upwards, the IR filter is placed horizontally and screwed in with fingers. For a tighter fit, a screwdriver (typically included with the TLC200 Pro) can be inserted into one of the driving holes and turned clockwise until tight. This ensures the IR filter is securely attached and properly aligned for optimal performance.

Once the lens and IR filter are installed, the focus adjustment is performed through the camera's menu. Users can navigate to the "Focus" menu on the TLC200 Pro, where an enlarged preview screen helps in adjusting the lens focus. By rotating the lens, users can achieve the desired sharpness for their subject. After setting the focus, aperture, and zoom, there is an option to tighten a screw to secure these settings, preventing accidental changes during long-term time-lapse recordings. This "Manually set up" feature provides an added layer of stability and precision for critical projects. The ability to adjust zoom and aperture manually directly on the lens offers a hands-on approach to framing and exposure control, giving users creative freedom over their time-lapse sequences.

Maintenance Features

Proper maintenance of the Brinno Lens BCS 24-70 is essential for ensuring its longevity and consistent performance. The lens comes with a top cover and a bottom cover, which should always be used when the lens is not attached to the camera or when it is being stored. These covers protect the delicate optical surfaces from dust, scratches, and other potential damage. Similarly, the IR Filter should be stored with its own case when not in use, preventing damage to its surface.

When removing an existing lens, such as the BCS 019, it is recommended to store it with its lens covers to protect the lens elements. This practice applies to all interchangeable lenses to maintain their optical integrity.

Environmental considerations are also crucial for maintenance. Users are advised to avoid storing the lens in locations with high temperatures or high humidity. Extreme conditions can potentially damage the lens coatings, internal components, or even foster mold growth, which can degrade image quality. Keeping the lens in a cool, dry environment is ideal for preserving its condition.

Regular cleaning of the lens surfaces is also important. While not explicitly detailed in the provided manual snippets, general lens care practices suggest using a soft, lint-free microfiber cloth specifically designed for optics, along with a lens cleaning solution if necessary, to remove dust, fingerprints, and smudges. Care should be taken to avoid touching the glass elements directly with fingers, as oils and dirt can leave residues that are difficult to remove and can affect image clarity. The manual highlights "DUST" and "FINGERPRINT" as factors to avoid, reinforcing the importance of keeping the lens surfaces clean.

In case of any questions or problems with the Brinno Time Lapse Camera Accessories, users are encouraged to contact the sales staff where they purchased the product or directly email Brinno Incorporated's customer service. This support system ensures that users can receive assistance with any operational or maintenance issues, contributing to a positive user experience and extending the lifespan of the product.
