There’s something inherently bold about launching a new lens series with a 16mm, especially when that lens is designed to cover a 65mm image circle. NiSi’s latest announcement, the 65 PRIME 16mm T2.9, isn’t just another ultra-wide. It’s a statement of intent. And having seen an early prototype firsthand, it’s one that carries more weight than you might expect.

There’s a fine line between innovation and indulgence in the world of cinema optics. Every so often, a new “look” emerges – not from the meticulous engineering of glass and coatings, but from the collective mood of an industry chasing something intangible. Character. Texture. Imperfection. Or, as it’s now being called – vibe. This year, Duclos Lenses leans into that ambiguity with the introduction of a groundbreaking new product.

DZOFilm’s new Arcana series enters an increasingly crowded anamorphic market with a familiar promise: deliver cinematic character without the traditional tradeoffs. Compact, lightweight, and relatively affordable, Arcana positions itself as a practical alternative to larger, more demanding anamorphic systems. The real question is not what it claims to do, but how much of the anamorphic experience it actually preserves in the process.

NiSi’s Athena primes earned attention by offering a clean, modern cinema lens platform at a price point that made sense for owner-operators, small productions, and growing rental inventories. The Athena Rewind series builds on that same foundation, though it is more accurate to describe these lenses as a modified version of the existing Athena primes than as an entirely new lens family.

Zeiss has announced the new Aatma Primes, a nine-lens full frame T1.5 cinema set that places the company squarely back into the conversation around vintage inspired optics. Covering focal lengths from 18mm through 135mm, Aatma is positioned as a more character forward option within Zeiss’ modern cinema lineup while retaining contemporary mechanics and workflow compatibility. In a market already dense with lenses aimed at nostalgia, Aatma presents an important consideration. Is this a meaningful refinement of Zeiss’ recent direction, or simply another option competing for attention?

Venus Optics has introduced the Laowa Sunlight 2x Full Frame Anamorphic Zoom Series, designed to make anamorphic filmmaking more versatile and accessible for full-frame users. Building on the success of the Laowa Proteus primes, these new zooms deliver the classic anamorphic look in a compact and lightweight form factor that’s easier to manage on set.

Vintage camera lenses from the mid-20th century often develop a yellow or brown tint as they age. This “yellowing” results in a warm color cast and reduced light transmission, impacting image quality. At Duclos Lenses, our technicians frequently encounter this issue in classic optics across a wide variety of lens brands. This article endeavors to explain the technical causes of lens yellowing and outlines the process of de-yellowing – the restoration of clear glass – using ultraviolet (UV) light. We will delve into the physics behind the discoloration, the UV treatment procedure (sometimes called annealing or bleaching), as well as the associated effects, risks, and benefits. The intended audience is lens technicians and engineers, so we will prioritize scientifically grounded knowledge over speculative or anecdotal information.

At Duclos Lenses, we have always had an eye for glass that goes beyond the look. There’s always more than meets the eyes when it comes to optics and we have an eye for spotting potential. Some might say we are optics experts. Canon’s newly announced CINE SERVO 11-55mm T2.95-3.95 PL and RF is reminiscent of a broadcast lens, but this servo is ready to rock cinema. With wide coverage, great resolving power, and suite of professional luxuries, this lens opens the door for creatives who need versatility with little compromise.

Leitz Cine has announced their newest lens line: the Hektor Primes, a six-lens set designed for today’s mirrorless cameras. Compact, consistent, and unapologetically character-driven, the Hektors represent a notable shift for Leitz Cine as they step into a price bracket and design philosophy aimed less at rental houses and more at working cinematographers who want artistry without sacrificing reliability or build quality.

Sigma has officially pulled the curtain back on the 28-45mm T2 FF, the first release in its brand-new AF Cine Line. Launching November 6, 2025, this lens is more than just another short zoom; it’s Sigma’s declaration that autofocus has a place in professional cinema production. Available in L-Mount and Sony E, the 28-45mm arrives with cine-style mechanics, the optical pedigree of Sigma’s Art series, and a high-response linear actuator for fast, near-silent autofocus. For Sigma, this is both a technical showcase and a philosophical challenge to decades of manual-only cinema tradition.

The Vespid II primes arrive with more than just a fresh coat of paint. DZOFilm has taken the core appeal of the original Vespid series and supercharged it with faster apertures, metadata support, and a refined lineup built for modern filmmaking. These lenses are not simply a sequel, they are a bold statement that DZOFilm is listening to creators and pushing their designs into territory once reserved for higher end cinema glass.

Leitz Cine quietly expanded its HUGO series this week with the announcement of a brand new 40mm T1.5 lens. Revealed on August 25, the addition rounds the set out to a total of 14 focal lengths spanning 18mm through 135mm.
The HUGO series quickly grabbed attention among cinematographers for the pleasing rendering they impart on the image and as more robust build than the M 0.8 primes that they replaced. Much of the glass in the series comes from Leica M rangefinder optics, known for their signature character and natural falloff toward the edges. While Leica does not currently make a 40mm in their M line, this lens was developed with support from Leica Camera designers to ensure it matched the spirit of the series.

Over the past decade, the world of cinema optics has opened up. Lens manufacturers, responding to the growing demand for flexibility, have embraced modularity—giving end-users the option to swap mounts, service mechanical components, and yes, even adjust their own back focus. This accessibility is a win for the working cinematographer, but with it comes a flood of assumptions and, frankly, some dangerous misinformation. Grab a cup of coffee and read on for a more in-depth understanding of this commonly misrepresented feature.

It’s late in the afternoon and I am sitting at my desk casually culling images for upcoming posts when I suddenly get called out to the service room. I walk in to see Michelle and Paul Duclos standing around a plastic bag on the desk with strange looks on their faces and pointing at me to open it. As I pull the plastic off, I come to realize what has them taken aback. A sad sight. Placed in the bag was a Canon K35 zoom that was completely caked with mushy deteriorated foam the same texture and stickiness of a toasted marshmallow.
My first thought: This is going to make a great story. The second: I need gloves.

Laowa has added a long-awaited piece to their expanding ultra-wide cine arsenal: a factory-built PL-mount version of the 10mm T2.9 Zero-D VV Cine. With support confirmed for professional motion picture cameras, this release rounds out what is arguably one of the most complete ultra-wide full-frame prime sets in recent memory. But while the optics remain unchanged, the mount matters.
