Smartphone cameras have evolved into remarkably capable creative tools, yet capturing clean cinematic footage often requires attaching optical hardware like neutral density filters or wide-angle conversion glass. In the earlier days of mobile video production, creators relied on friction clamps such as an olloclip mobile photography lens box set for iphone x to secure extra optics over camera lenses. Today, mobile filmmakers favor precision mounts integrated directly into dedicated smartphone cages. The Neewer PA173 Lens Backplate addresses this exact need by providing a secure, threaded mounting plate tailored for modern high-end phones. If you are shopping for a creator or searching for a smartphone camera lens mount for beginners, understanding how modular camera plates interface with protective cases is the most critical first step before buying extra glass.
Designed specifically as an expansion component for mobile video creators, this silver aluminum adapter slides directly into a matching cage setup to accept standard threaded accessories. Our verdict is that this backplate is a well-engineered, lightweight solution for owners of the corresponding cage, offering rock-solid lens alignment without complicated tools, though its strict hardware compatibility means you must verify the existing phone setup before gifting or purchasing.
Neewer PA173 Lens Backplate Features Explained
Dedicated PA133 Case Slide-On Mechanism
One of the primary frustrations beginner creators face when mounting glass to a phone is alignment error. Universal lens clips frequently slip out of position, cutting off the frame or creating unwanted vignetting around the edges of your image. The Neewer PA173 avoids this issue entirely by utilizing a custom-fit slide-on design. Built to function exclusively as a Neewer PA133 phone case adapter, this plate slides along precision-machined grooves until it clicks securely into place over the camera module.
This tool-free design means you do not need tiny hex wrenches, thumbscrews, or complex hardware when preparing your phone for a shoot. For beginners or content creators working in fast-paced environments, being able to quickly attach or remove your lens mount in seconds keeps your creative flow uninterrupted. Once engaged, the mechanical slide mount ensures your external optics stay centered over the native camera glass without shifting during movement.
Standard 37mm Threading for Filters and External Lenses
The defining characteristic of this Neewer 37mm lens backplate is its standardized threaded mount. In video production and photography, a 37mm thread is an established standard that gives you direct access to a vast ecosystem of creative optical tools. By threading filters directly in front of the phone camera, creators can use circular polarizers to remove reflections from water and glass, or mount variable neutral density filters to control shutter speed in bright outdoor conditions.
Beyond flat glass filters, the 37mm thread also functions seamlessly as a Beastgrip 37mm lens adapter iPhone compatible solution. This threading standard allows creators to attach compatible Beastgrip wide-angle and anamorphic lenses, giving mobile videographers cinema-style flares, broader fields of view, and distinct optical character. Having standard threads turns a standard smartphone into a versatile cinematic rig that mimics professional mirrorless cameras.
Protective and Non-Slip Internal Padding
Attaching rigid metal accessories directly around delicate smartphone camera rings can understandably make any gear owner nervous. Neewer addresses this concern by outfitting the inner contact surfaces of the backplate with soft, non-slip protective pads. These miniature pads act as a physical buffer between the aluminum frame of the backplate and the camera components, absorbing friction during installation and everyday handling.
In addition to shielding against accidental scratches, the non-slip material plays a functional role in stabilizing attached glass. When heavy glass elements or larger polarizing filters are screwed into the front thread, the internal pads provide friction that resists micro-vibrations. This prevents the backplate from shifting or rattling against the housing, ensuring steady footage whether you are filming handheld b-roll or vlogging on location.
Lightweight Aluminum Alloy Construction
Mobile rigs need to remain agile and easy to hold for extended recording sessions. Built from rigid aluminum alloy, this backplate provides high structural rigidity while maintaining an astonishingly low weight of approximately 0.3 ounces (8 grams). The aluminum frame resists bending, thread stripping, and impacts, ensuring that repeated screw-in filter adjustments will not wear down the internal thread tracks over time.
Keeping your camera accessories lightweight is particularly critical if you plan to balance your smartphone on a motorized stabilizer such as a dji gimbal 7. Adding heavy front-loaded components can easily strain small gimbal motors and disrupt balancing calibration. Because this backplate adds virtually negligible bulk, using the Neewer PA173 for mobile video keeps your entire camera cage nimble, compact, and ready for long shooting days.

Think twice if
Before You Buy
The single most important factor to verify prior to ordering is Neewer PA173 iPhone 17 Pro compatibility. This backplate is engineered exclusively to mount onto the Neewer PA133 phone case and will not fit directly onto a bare smartphone or third-party protective cases. If the creator you are buying for does not already own the specific PA133 case, this backplate cannot be attached on its own. While universal clip-on lenses like an apexel 36x telephoto rely on spring tension clamps to grip various handsets, modular camera plates require their specific base cage to function.
Gift-givers and first-time buyers should also review the package contents carefully before placing an order. The listing includes one silver aluminum backplate, but it does not supply the PA133 case, external lenses, or optical filters in the box. The listing does not specify any carrying pouch or step-up adapter rings. Anyone purchasing this plate should plan on acquiring their desired 37mm threaded filters or compatible lenses separately to complete the camera setup.
Bottom Line
The Neewer PA173 provides a focused, high-quality hardware upgrade for content creators who have embraced mobile video on the iPhone 17 Pro platform. By transforming the PA133 case into a standardized optical mount, it grants immediate access to an extensive world of 37mm circular polarizers, neutral density filters, and specialized Beastgrip lenses. The tool-free slide-on mechanism makes swapping gear seamless, while the sturdy aluminum alloy and soft internal padding ensure your gear stays protected and properly aligned throughout demanding shoots.
For beginners who already own or plan to purchase the corresponding Neewer protective case, this backplate is a reliable, durable investment that dramatically elevates mobile video quality. As long as you confirm that your recipient has the matching case and understands that optical filters must be purchased separately, this compact accessory makes a practical and thoughtful addition to any aspiring creator’s production kit.
FAQ
Can the Neewer PA173 be attached directly to an iPhone without the PA133 case?
No, this backplate cannot attach directly to a bare iPhone or any standard third-party silicone or plastic case. It is engineered specifically with guide rails that slide exclusively into the Neewer PA133 phone case for the iPhone 17 Pro. Attempting to use it without the PA133 case will result in no attachment mechanism or lens alignment.
What camera accessories can be screwed into the 37mm thread?
Any photography or cinematography filter with standard 37mm male threading can be mounted onto this backplate. Common options include neutral density (ND) filters to control exposure in bright lighting, circular polarizers (CPL) to cut unwanted reflections, and diffusion mist filters to soften digital sharpness for a film-like aesthetic.
Does the backplate scratch the iPhone 17 Pro camera bump?
The backplate features soft, non-slip internal protective pads designed specifically to prevent surface scratches during attachment and use. These pads create a protective barrier between the rigid aluminum alloy frame and your phone hardware, ensuring the camera lenses and housing remain shielded from metal-on-metal contact.
Can this setup be used alongside mobile wireless microphones and audio rigs?
Yes, because this backplate mounts cleanly onto the rear camera window of the PA133 case, the base charging port and rig handles remain completely unobstructed. This allows mobile filmmakers to plug in compact wireless audio receivers like the dji mic mini (2 tx + 1 mobile rx), wireless lavalier microphone for iphone 17/16/15 & android/pc/tab simultaneously without interference.
Is any special tool or screwdriver required to install or remove the plate?
No tools are needed to attach or detach the backplate. It features a quick-release slide-on mounting system that glides smoothly into the matching receiver slots on the phone case until it locks into place. You can install it or remove it by hand in just a couple of seconds whenever you want to switch setups.
