Pro Series 1.7X Telephoto Lens

The Beastgrip 1.7X Telephoto Lens provides true optical magnification, narrowing the field of view by approximately 1.7X. This allows you to capture tighter framing, compress perspective, and bring distant subjects closer without using digital zoom.

For example, when used on the main camera of iPhone Pro models, the lens produces an effective focal length equivalent of approximately 40mm. When combined with the iPhone’s 2X in-camera zoom, it can achieve an effective focal length of approximately 80mm, making it ideal for portraits, interviews, and cinematic close-ups.

The Beastgrip 1.7X Telephoto Lens provides true optical magnification that is applied across the full camera sensor resolution, without digital cropping. This means image detail, sharpness, and color accuracy are preserved at the native resolution of the camera.

Modern smartphones also offer a range of lossless or near-lossless in-camera zoom using high-resolution sensors. When combined with these camera systems, the 1.7X telephoto lens adds additional optical magnification on top of the phone’s native capabilities, extending usable focal lengths while maintaining high image quality.

The Beastgrip 1.7X Telephoto Lens works best when aligned with the main (wide) camera on modern smartphones. The main camera typically offers the largest sensor, widest aperture, and highest overall image quality, making it the ideal base for additional optical magnification.

The 1.7X Telephoto Lens can also be used with built-in telephoto cameras on smartphones. It delivers excellent optical results when used with tele cameras up to approximately 3X optical zoom.

On 4X and 5X telephoto cameras, the lens still produces very good results; however, depending on the scene and lighting conditions, some optical aberrations or edge softness may become visible toward the edges of the frame due to the combined optical magnification.

While many smartphones include built-in telephoto cameras, these cameras often use smaller sensors and slower apertures compared to the main camera. The Beastgrip 1.7X Telephoto Lens allows creators to extend the focal length of the main camera instead, preserving higher image quality, better low-light performance, and more natural color and detail.

Using an external optical lens also provides greater creative control, more consistent results, and the ability to combine optical magnification with modern lossless in-camera zoom for extended focal lengths.

The Beastgrip 1.7X Telephoto Lens can be used with both native and third-party camera apps. However, the recommended approach depends on the smartphone platform and available camera controls.

On iPhone, using a third-party camera app is recommended for the best experience and consistent results. In the native iPhone Camera app, particularly in Photo mode, the system may automatically switch between cameras based on lighting, zoom level, or scene conditions. Third-party camera apps allow manual camera selection and full control over focus, exposure, and zoom, ensuring consistent use of the intended camera.

On Android, many devices include a native Pro or Manual mode that allows users to manually select and control individual cameras. When such a mode is available, the native camera app can work very well with external lenses. The choice between native and third-party apps on Android depends on the specific device and the user’s preference for manual control.

Yes. The Beastgrip 1.7X Telephoto Lens is designed for use in both photography and video applications, delivering consistent optical performance for still images as well as cinematic video capture.

For video, the lens works especially well for interviews, narrative filmmaking, close-ups, and detail shots where tighter framing, perspective compression, and subject separation are desired. For photography, it is well suited for portraits, nature, sports, and close-up compositions.

As noted above, using a third-party camera app is recommended on iPhone to maintain manual control over camera selection and ensure consistent lens alignment during both photo and video capture. This provides more predictable results, particularly in professional video workflows.

The Beastgrip 1.7X Telephoto Lens is compatible with a wide range of smartphones when used with Beastgrip mounting systems such as Beastcage for iPhone or the Beastgrip Pro universal rig. Compatibility is determined by the mounting system and proper camera alignment, rather than the phone brand itself.

The lens can be used with modern iPhone and Android smartphones, including devices with single, dual, or multi-camera systems. For best optical performance, proper alignment with the intended camera, most commonly the main camera, is recommended.

The Beastgrip 1.7X Telephoto Lens is best used in situations where tighter framing and natural perspective compression are needed without relying on digital zoom. It is especially well suited for:

• Portraits with more natural facial proportions
• Interviews and talking-head shots
• Cinematic close-ups and detail shots
• Sports, wildlife, and outdoor scenes
  

When shooting close-up subjects, the increased focal length also results in a shallower depth of field compared to wider lenses, helping to further isolate the subject and create a more cinematic look while preserving image quality and detail.

Yes. The Beastgrip 1.7X Telephoto Lens features a standardized front filter mount, allowing the use of ND, polarizer, and creative filters for both photo and video applications.

The lens includes a 62mm filter thread and is supplied with a 77mm step-up ring, making it easy to integrate into professional filter workflows and share filters across different Beastgrip lenses.

The Beastgrip 1.7X Telephoto Lens is designed to be used as a standalone optical lens for optimal performance. Stacking the lens with additional lenses or adapters is generally not recommended, as combining multiple optical elements can introduce increased distortion, vignetting, or optical aberrations.

The only stacking configuration recommended by Beastgrip is the use of the Beastgrip 77mm Close-up Filter, which is purpose-built to work with the lens. The close-up filter reduces the minimum focus distance, allowing for closer focusing and shallower depth of field in close-up shots while maintaining controlled optical performance.

Other stacking combinations may be experimented with by advanced users, but image quality and edge performance will vary depending on the setup. For consistent, predictable results, using the lens on its own, or with the dedicated close-up filter, is recommended.

Proper mounting and precise alignment are critical for optimal performance. When the Beastgrip 1.7X Telephoto Lens is correctly aligned using a compatible Beastgrip mount, it produces no visible vignetting on the main camera of most modern iPhones (approximately 24mm equivalent) in standard 16:9 shooting modes.

On some Android devices with wider main cameras, a slight vignetting may be visible depending on the camera’s field of view. In many cases, in-camera image stabilization or digital stabilization introduces a small crop that effectively eliminates any visible vignetting.

When shooting in open-gate or 4:3 modes, such as open-gate recording on iPhone 17 Pro models, a very slight mechanical vignetting may appear in the extreme corners, especially when additional filters or adapters are used. Thick filters or stacked filter setups can increase the likelihood of edge darkening.

In all scenarios, correct mounting, careful alignment, and appropriate filter selection ensure excellent optical performance with minimal edge artifacts under normal shooting conditions.

Any optical system that introduces additional glass elements into the light path, including professional camera lenses, will introduce optical characteristics such as distortion, flare, or minor aberrations. This is a normal and expected part of optical design.

High-quality conversion lenses are engineered to minimize unwanted optical issues while intentionally enhancing others. The Beastgrip 1.7X Telephoto Lens introduces minimal pincushion distortion and may add additional flares or subtle aberrations depending on lighting conditions. These characteristics contribute to image compression, shallower depth of field in close-up shots, and a more cinematic rendering that differs from the typical smartphone camera look.

External lenses are a creative tool, just like lenses used on traditional cameras. The purpose is not only magnification, but also to introduce optical qualities, such as perspective compression, depth separation, and natural lens artifacts, that enhance the image and give creators greater control over the final look.
