Canon RF 135mm F1.8 - Filmmaker's Review
For filmmakers, the tools we choose can make or break our creative vision. As someone who’s navigated the challenges of crafting compelling visuals, I know how important it is to have gear that matches your ambition. Enter the Canon RF 135mm F1.8 lens—a telephoto powerhouse with promises of razor-sharp images, creamy bokeh, and unparalleled low-light performance. But is it the right fit for your filmmaking needs?
In this guide, I’ll walk you through the strengths and quirks of this lens, sharing insights gained from real-world use. Whether you’re shooting weddings, corporate events, or portraiture, by the end of this read, you’ll know if this lens deserves a spot in your toolkit.
Understanding the Canon RF 135mm F1.8
The Canon RF 135mm F1.8 lens is a telephoto prime designed to deliver incredible reach and stunning subject isolation. Its focal length and wide aperture make it a niche but impactful choice for filmmakers who prioritize detail and depth.
But here’s the catch:
Its telephoto nature demands space for proper composition.
It’s not ideal for tight interiors or small studios.
It requires thoughtful planning to get the best out of its capabilities.
That said, when you have room to work, this lens excels. From wedding ceremonies to nature shoots, it lets you create cinematic visuals that feel larger than life.
Key Features for Filmmakers
1. Design & Build
This lens is built like a tank, which is no surprise given it’s part of Canon’s premium L-series lineup. At 5.3 inches long and weighing 2.1 pounds, it’s not exactly compact. Add the lens hood, and you’re looking at an 8-inch setup.
While this size isn’t ideal for discretion, the robust build inspires confidence. The Ultra-Low Dispersion glass and specialized coatings minimize ghosting and flaring, even in backlit conditions—a huge plus for outdoor shoots.
Pro Tip: If portability is a concern, factor in a sturdy lens bag or a larger camera backpack for safe storage.
2. Image Stabilization
Canon reports up to 8 stops of image stabilization when paired with an IBIS-capable camera like the Canon R6 Mark II. In practice, this makes handheld telephoto shooting surprisingly smooth. Whether you’re capturing emotional vows at a wedding or candid moments at a corporate event, you can rely on its stability for professional-grade results.
3. Low Aperture Magic
The lens’s standout feature is its f/1.8 aperture, offering:
Dreamy bokeh and beautiful background separation.
Excellent low-light performance for events or dimly lit venues.
Unique visual flair that helps your work stand out.
However, when shooting wide open, I found that focus sharpness can soften slightly for full-body shots. Stopping down to f/2.8 or f/4 noticeably improves clarity while retaining strong subject isolation.
4. Usability in Real-World Scenarios
The RF 135mm isn’t for every situation, but when used wisely, it shines. Here’s where it works best:
Events: Great for capturing intimate moments from afar.
Portraits: Perfect for waist-up or close-up shots, thanks to its flattering compression.
Product Shots: Ideal for isolating small details with finesse.
Low Light Scenes: Handles dim conditions beautifully with minimal noise.
Challenges:
Tight indoor spaces and rapid reframing can feel restrictive.
Its focus breathing—visible when racking focus—is a drawback. Canon’s focus-breathing compensation feature helps but introduces a crop.
Final Verdict: Who is This Lens For?
This lens isn’t for everyone. But for filmmakers who:
Work in spacious environments like outdoor weddings or sports events.
Prioritize unique framing and stunning bokeh.
Want a versatile tool for portraits and detail shots…
…it’s a game-changer.
At $2,100 (with occasional $300 discounts), it’s an investment. But if your work aligns with its strengths, the RF 135mm F1.8 can elevate your visuals and distinguish your portfolio.
Actionable Insights for Filmmakers
Plan Your Shots: This lens demands space and intention. Scout locations and visualize compositions before setting up.
Use Stabilization to Your Advantage: Pair the lens with IBIS for handheld event work or dynamic shots.
Experiment with Aperture: Test different f-stops to find the perfect balance of sharpness and background blur.
Mind the Details: Be aware of focus breathing and cropping when compensating.
This lens isn’t just a tool—it’s a creative partner that challenges you to think differently. If you’re up for the challenge, the Canon RF 135mm F1.8 might just transform how you see and capture the world.
Happy shooting! 🎥
