The 100mm telephoto delivers professional results that rival lenses costing 10 times more.

Best Sirui Anamorphic Lenses for Mirrorless Camera Video in 2026

Here is every Sirui anamorphic lens we tested, compared side by side. The comparison table below covers sensor compatibility, squeeze factors, and mount options to help you quickly identify which lens fits your camera system.

1. Sirui 40mm T1.8 1.33X Autofocus – World’s First AF Anamorphic

I remember the exact moment I tested the autofocus on this lens. Tracking a subject walking toward the camera, the 40mm held focus with my Sony FX3’s eye-AF engaged. For solo filmmakers who work without a focus puller, this capability changes everything.

The 40mm focal length on Super 35 gives you roughly a 50mm full-frame equivalent field of view. This makes it the most versatile starting point for narrative work, interviews, and run-and-gun documentary shooting. The T1.8 aperture delivers excellent low-light performance and shallow depth of field for subject separation.

Community discussions on r/bmpcc and r/videography consistently praise this lens as a “game-changer for single operators.” The STM stepping motor provides smooth focus transitions, though you will hear it if you record audio in-camera in quiet environments. I recommend using an external recorder or shotgun mic positioned away from the camera.

Build quality impresses for the price point. The lens weighs just 614 grams, making it ideal for gimbal work and handheld shooting. The geared focus and aperture rings integrate seamlessly with follow focus systems when you want manual control. The 77mm filter thread accepts standard ND and diffusion filters.

Image quality delivers the signature anamorphic look with neutral flare characteristics. You get horizontal streaks when pointing toward light sources, but the effect remains subtler than the dramatic blue flares of the Venus series. The oval bokeh at T1.8 transforms backgrounds into creamy abstractions that immediately elevate production value.

One limitation to understand: Sony cameras disable internal de-squeeze when using this lens. You will need to monitor in squeezed mode or use an external monitor with de-squeeze capabilities. Most users adapt quickly to this workflow quirk.

Best Use Cases for This Lens

Solo creators who need reliable autofocus for YouTube content, wedding videographers capturing moving subjects, and documentary filmmakers working without a crew will benefit most. The 40mm length works equally well for interviews and B-roll capture. If you shoot primarily on Super 35 cameras like the FX30, A6700, or Blackmagic Pocket Cinema Camera 4K, this lens maximizes your sensor while delivering cinematic character.

Who Should Consider Alternatives

Full-frame shooters who want maximum width should look at the Venus series with 1.6x squeeze. The 40mm covers Super 35 only, leaving heavy vignettes on full-frame sensors unless you crop. Filmmakers requiring absolute silence during takes need manual focus lenses or external audio solutions. Those seeking the most dramatic anamorphic flares will prefer the blue flare options in other Sirui lines.

2. Sirui 20mm T1.8 1.33X Autofocus – Wide Angle Game Changer

Wide angle anamorphic lenses present unique challenges. The optical complexity increases with field of view, making affordable options rare. Sirui’s 20mm T1.8 solves this while adding autofocus, creating the widest automated anamorphic option for mirrorless cameras.

The horizontal field of view equates to approximately 22mm on full-frame after accounting for the 1.33x squeeze. This captures expansive establishing shots, tight interior spaces, and immersive vlogging perspectives. For real estate videos, music videos in confined locations, or documentary work where you cannot back up further, this focal length delivers.

At 480 grams, this is the lightest lens in Sirui’s anamorphic lineup. Mounted on smaller bodies like the Sony ZV-E10 or A6500, the combination remains comfortable for all-day handheld shooting. Gimbal operators appreciate the reduced weight for balancing and extended takes.

Image quality impresses with sharp results across the frame when stopped down slightly. Wide open at T1.8, expect some softness in corners that resolves by T2.8. The anamorphic character remains subtle compared to the 1.6x squeeze lenses, giving footage a gentler cinematic enhancement rather than dramatic distortion.

Autofocus performance matches the 40mm sibling with eye-tracking and face detection compatibility. The STM motor operates quietly enough for most situations, though sensitive audio work still benefits from manual focus or external recording. The 2.35:1 aspect ratio in 16:9 mode provides that widescreen cinematic look without cropping your sensor.

Real-world testing revealed excellent results for vlogging and self-shooting scenarios. The wide angle keeps you in frame at arm’s length while the autofocus maintains sharp eyes even as you move. For creators producing content alone without a camera operator, this combination removes significant technical barriers.

Best Use Cases for This Lens

Real estate videographers shooting interiors, vloggers and content creators filming themselves, gimbal operators needing lightweight wide coverage, and documentary filmmakers working in tight spaces will find this lens essential. The combination of wide angle, autofocus, and anamorphic character fills a unique niche in the market.

Who Should Consider Alternatives

Those seeking dramatic anamorphic distortion and pronounced flares should consider the 1.6x Venus or Saturn series. The 1.33x squeeze provides a gentler effect that some users find too subtle. Full-frame shooters requiring complete sensor coverage need the Venus lineup rather than this Super 35 option. If you rarely shoot wide, the 40mm or 50mm options provide more versatile framing.

3. Sirui 50mm F1.8 1.33X Entry – Best Budget Anamorphic

When Sirui released this lens, they disrupted the entire anamorphic market. At under $300, it brought cinematic capabilities to creators who previously could only dream of owning anamorphic glass. Three years and hundreds of reviews later, it remains the best entry point into anamorphic cinematography.

The 50mm focal length on APS-C sensors provides approximately 75mm full-frame equivalent perspective. This creates flattering portraits, compressed background separation, and cinematic interview framing. The 1.33x squeeze transforms standard 16:9 footage into 2.4:1 widescreen without cropping, preserving full sensor resolution.

Building on user reports from Reddit communities, this lens consistently earns praise for delivering “80% of the anamorphic look at 10% of the traditional cost.” The blue flare effects create horizontal streaks when light sources hit the front element, delivering that sci-fi cinematic aesthetic immediately recognizable from Hollywood blockbusters.

Manual focus operation requires practice but rewards skilled operators. The 143.6-degree focus ring rotation provides sufficient precision for rack focusing between subjects. Anti-slip teeth on the rings work with follow focus systems when rigged properly. The all-metal aluminum housing withstands regular use better than plastic alternatives.

Image quality produces sharp centers wide open with gradual softening toward corners. Stopping down to F2.8 improves edge performance significantly. The oval bokeh from the 10-blade aperture creates dreamy background rendering that elevates even simple scenes. German-made Schott glass elements deliver excellent color rendition and contrast.

Low light performance benefits from the F1.8 maximum aperture. Shooting indoors, at dusk, or in dimly lit venues becomes possible without pushing ISO excessively. This capability alone justifies the investment for wedding videographers and event shooters working in unpredictable lighting.

Best Use Cases for This Lens

First-time anamorphic buyers testing the format, budget-conscious filmmakers building their kit, students learning cinematic techniques, and secondary camera operators needing matching anamorphic coverage will all benefit. The combination of affordable price and capable performance makes this the recommended starting point for anyone curious about anamorphic shooting.

Who Should Consider Alternatives

Full-frame camera owners should skip this lens for the Venus series. The APS-C coverage vignettes heavily on full-frame sensors. Creators requiring autofocus for solo work need the Astra 40mm instead. Those seeking 1.6x squeeze factor for more dramatic anamorphic effects should upgrade to Saturn or Venus lines. Professional productions demanding absolute optical perfection may need higher-end cinema lenses.

4. Sirui 24mm F2.8 1.33X Entry – Wide Budget Option

The 24mm F2.8 complements the 50mm F1.8 as the wide-angle counterpart in Sirui’s entry series. Together they form a two-lens kit covering essential focal lengths for under $600 total, an unprecedented value in anamorphic cinematography.

This lens squeezes a 0.6-meter minimum focusing distance into the design, allowing closer subject shooting than the 50mm’s 0.85-meter limitation. For product videography, food content, and detail work, this close-focus capability expands creative possibilities. The wide 24mm perspective captures environmental context while the anamorphic squeeze adds cinematic width.

Construction matches the 50mm sibling with precision aluminum alloy housing and Schott glass elements with Nano-coating. The 1-kilogram weight feels substantial without becoming burdensome for handheld work. The Amazon’s Choice designation reflects strong customer satisfaction and reliable fulfillment.

Image characteristics mirror the entry series aesthetic: blue horizontal flares, oval bokeh, and that 2.4:1 cinematic aspect ratio. The F2.8 aperture, while not as fast as the 50mm’s F1.8, still performs admirably in moderate low light. For exterior work and well-lit interiors, the difference proves negligible.

Best Use Cases for This Lens

Budget filmmakers needing wide anamorphic coverage, gimbal operators seeking lightweight wide options, real estate videographers on tight budgets, and creators pairing with the 50mm for a two-lens kit will maximize value. The 24mm excels for establishing shots, interior walkthroughs, and immersive POV sequences.

Who Should Consider Alternatives

Filmmakers working primarily in low light benefit from the 50mm F1.8’s faster aperture or the Astra 20mm T1.8. Anyone wanting 1.6x squeeze effects needs to look at premium Sirui lines.

5. Sirui Saturn 35mm T2.9 1.6X – Lightweight Full Frame

The Saturn series represents Sirui’s pursuit of lightweight full-frame anamorphic design. Using carbon fiber construction techniques, the 35mm T2.9 weighs just 418 grams while covering full-frame sensors with a dramatic 1.6x squeeze factor. For comparison, the equivalent Venus 50mm weighs over twice as much.

This weight reduction transforms what is possible with anamorphic lenses. FPV drone operators can now capture cinematic footage without exceeding payload limits. Gimbal users extend shooting sessions without arm fatigue. Handheld documentary work becomes sustainable for longer takes. The compact 101mm length fits in camera bags that would never accommodate cinema anamorphics.

The 1.6x squeeze delivers more dramatic anamorphic character than the 1.33x entry lenses. Your 2.4:1 aspect ratio extends further to 2.8:1 on 16:9 sensors, approaching the extreme widescreen of epic cinema. The oval bokeh becomes more pronounced. The flares stretch longer across the frame. Everything looks bigger and more cinematic.

Forum discussions reveal the trade-offs. The focus ring stiffness frustrates some users attempting smooth focus pulls. Significant barrel distortion requires correction in post for architectural work. The 0.9-meter minimum focus distance limits close-up capabilities without diopter filters. These compromises accompany the weight savings.

Best Use Cases for This Lens

FPV and drone cinematographers needing full-frame coverage, gimbal operators prioritizing lightweight balance, run-and-gun documentary shooters requiring mobility, and overhead rig installations where weight limits apply will find this lens uniquely suited.

How to Choose the Best Sirui Anamorphic Lens for Your Needs In 2026?

Selecting the right anamorphic lens requires understanding several technical factors that affect your final image. This buying guide breaks down the key considerations to help you make an informed decision for your mirrorless video work.

Sensor Coverage: APS-C vs Full Frame vs Super 35

Sirui organizes their lenses by sensor coverage. The entry series with 50mm F1.8 and 24mm F2.8 covers APS-C sensors only. Using these on full-frame cameras produces heavy vignetting unless you crop significantly. The Astra autofocus series covers Super 35, working perfectly on cameras like the FX30 and A6700 while requiring crop mode on full-frame bodies.

The Venus and Saturn series provide full-frame coverage, utilizing your entire sensor without compromise. These lenses work natively on Sony A7 series, Nikon Z, Canon R, and other full-frame mirrorless systems. The larger image circle demands more complex optical design, explaining the higher prices.

Squeeze Factor: 1.33x vs 1.6x

The squeeze factor determines how horizontally compressed your image becomes during capture. A 1.33x squeeze transforms 16:9 footage into 2.4:1 widescreen when de-squeezed. This milder distortion produces subtle anamorphic character while remaining manageable for beginners. The Astra and entry series use this squeeze factor.

The 1.6x squeeze in Venus and Saturn series creates more dramatic effects. Your footage expands to 2.8:1 aspect ratio, approaching the extreme widescreen of epic cinema. The oval bokeh becomes more pronounced. Flares stretch further. Distortion increases. Experienced cinematographers often prefer this more distinctive look.

Autofocus vs Manual Focus

The Astra 40mm and 20mm T1.8 lenses represent a technological breakthrough as the world’s first autofocus anamorphic lenses. Their STM motors enable eye-tracking, face detection, and continuous AF during video recording. Solo operators, vloggers, and run-and-gun shooters benefit enormously from this capability.

Manual focus lenses require skill and often a focus puller for professional work. The longer focus throw distances common in cinema lenses demand practice to master. However, manual focus provides tactile control and consistency that some cinematographers prefer. Narrative filmmakers with crews often choose manual Venus lenses for this reason.

Focal Length Selection Guide

Wide angles between 20mm and 35mm excel for establishing shots, environmental portraits, and immersive sequences. The 20mm Astra and 24mm entry lenses serve these purposes. Standard focal lengths around 40mm to 50mm work as versatile all-around options for interviews, medium shots, and general coverage. The 40mm Astra, 50mm entry, and 50mm Venus fill this role.

Telephoto options at 100mm compress perspective and isolate subjects dramatically. The Venus 100mm creates exceptional subject separation and flattering facial rendering. Most cinematographers start with a standard length, then add wide and telephoto options as budgets allow.

De-Squeeze Workflow Basics

All anamorphic footage requires de-squeezing in post-production to display properly. This process stretches the horizontally compressed image back to correct proportions, revealing the widescreen aspect ratio. Most editing software including Premiere Pro, DaVinci Resolve, and Final Cut Pro includes anamorphic de-squeeze options.

Monitoring anamorphic footage while shooting requires either external monitors with de-squeeze capability or learning to judge composition in the squeezed view. Some cameras offer in-camera de-squeeze for monitoring, though this typically disables when using certain lenses. Budget for an external monitor if you plan extensive anamorphic work.
