The Canon RF 16mm f/2.8 STM lens is a compact, ultra-wide prime lens beloved by landscape photographers, vloggers, architecture enthusiasts, and creators seeking high-quality performance at an affordable price. Despite its advantages, like many ultra-wide lenses, it is prone to lens flare, glare, and light reflections, especially under bright lighting conditions.
Although Canon doesn’t officially offer a lens hood for this model, a 3d-printed lens hood offers an efficient, cost-effective, and customizable solution. It helps improve image quality and protects the lens’s front element. This guide covers everything you need to know to design, print, and use a custom DIY lens hood for your Canon RF 16mm f/2.8 lens.
Why Use a 3d-Printed Lens Hood?
There are multiple advantages to 3D printing your lens hood:
- Perfect Custom Fit: Unlike universal lens hoods, a 3d-printed version can be tailored to the exact diameter and angle of view of the Canon RF 16mm.
- Enhanced Light Management: Reduces lens flare, ghosting, and stray light, particularly useful for shooting outdoors.
- Affordability: 3D printing is significantly more economical than buying branded or third-party accessories.
- Lightweight but Durable: Designed with strong, lightweight materials that won’t burden your camera setup.
- Personalisation: Add your name, brand, or custom design to the hood for a professional look.
Best Materials for 3D-Printed Lens Hoods
Selecting the right filament is critical for optimal function, longevity, and strength:
1. PLA (Polylactic Acid)
- Pros: Easy to print, biodegradable, rigid finish
- Cons: Not heat-resistant; may warp under direct sunlight
- Best For: Studio or indoor photography
2. PETG (Polyethene Terephthalate Glycol)
- Pros: High durability and moderate flexibility; UV resistance
- Cons: Can be stringy during printing
- Best For: Outdoor shoots and moderate environments
3. ABS (Acrylonitrile Butadiene Styrene)
- Pros: Tough and heat-resistant
- Cons: Produces fumes while printing; needs a heated bed
- Best For: Harsh conditions or professional use
4. TPU (Thermoplastic Polyurethane)
- Pros: Flexible, impact-resistant
- Cons: More challenging to print, slow speeds needed
- Best For: Impact-prone environments or experimental builds
Designing the Ideal Lens Hood
Creating a lens hood tailored for the RF 16mm f/2.8 requires attention to fit and functionality:
Step 1: Accurate Measurement
- Measure the outer diameter and angle of view to avoid vignetting.
Step 2: Choose a Hood Style
- Petal Hoods: Ideal for minimising shading in ultra-wide shots
- Round Hoods: Easier to print and more protective
Step 3: Print Settings
- Layer Height: 0.2mm for a balance between speed and quality
- Infill: 20–30% for solid structure without weight
- Print Speed: 40–60mm/s to ensure accuracy
- Supports: May be needed for petal shapes
Step 4: Post-Processing
- Sanding: Smooth edges for clean attachment
- Painting: Use matte black spray paint to reduce internal reflections
- Test Fit: Ensure a snug and secure connection to the lens ring
Additional Design Tips
- Add internal grooves or friction locks for improved grip
- Consider a bayonet mount replica if you’re modelling it after Canon’s locking system
- Use anti-reflective coatings on the inside to reduce any micro-reflections from the plastic
Common Problems and How to Solve Them
- Loose Fit: Adjust tolerances in your 3D modeling software; use grip tape as a temporary fix
- Warping: Use a heated bed and proper adhesives when printing with ABS or PETG
- Vignetting: Redesign with a shorter hood length or use a petal design to reduce field-of-view blockage
- Internal Reflections: Coat the interior with matte black paint or line with flocked paper
Real-Life Applications of DIY Lens Hoods
- Vlogging Outdoors: Prevent flares when recording in sunlight
- Landscape Photography: Maintain contrast in wide-angle shots
- Street Photography: Adds subtle protection in fast-paced environments
- Studio Shoots: Minimises overhead light reflections
- Drone Use: Reduce flare and increase protection for mounted cameras

FAQs
1. Will a 3d-printed lens hood affect image quality?
No, a well-designed hood improves image quality by reducing flares and protecting the lens. Proper sizing avoids vignetting.
2. Can I use a 3d-printed hood for video recording?
Yes. It’s excellent for video, especially when recording under strong light or moving through different lighting conditions.
3. How durable is a 3d-printed lens hood?
Durability depends on the material. ABS and PETG are ideal for long-term, rugged use. PLA is fine for casual or indoor use.
4. Where can I download free STL files?
Search platforms like Thingiverse, MyMiniFactory, and Cults3d for ready-to-print Canon RF 16mm lens hoods.
5. Can I adapt this hood design to fit other lenses?
Absolutely. Use CAD software like Fusion 360 or Tinkercad to adjust the hood’s inner diameter and depth to fit different lenses.
Conclusion
For photographers and videographers looking to eliminate lens flare, glare, and stray light while protecting their Canon RF 16mm f/2.8 lens, a 3d-printed lens hood is a smart and rewarding DIY solution. With the right materials, precise modelling, and proper print settings, you can create a durable, cost-effective accessory customised to your exact needs.
