Just looking at the Sigma BF camera will reveal an appealing aesthetic that is unmatched by anything else in the industry. It features a true aluminum unibody—the first full-frame camera to ever offer such as design—that is incredibly rigid. To even make the body requires seven hours of machining from a single, solid block of aluminum. The size and weight balance wonderfully with Sigma’s renewed I series optics.

A sleek body is nothing without a sleek set of controls and Sigma has refined the control scheme in the BF. It has a completely redesigned interface that breaks down main functions, secondary settings, and management settings across three menus. The main display is a 3.15″ touchscreen which serves as your usual live view while a status monitor provides at-a-glance information. When combined with the rear dial you can quickly and intuitively get to the exact setting you need.

With minimal controls, just three buttons, one dial, and a shutter release, the BF is designed to let photographers focus on what matters—the photographs. It also features haptics in the dial and buttons to minimize physical wear and create a modern experience.

The camera also features internal storage—230GB to be exact—which supports up to 14,000 JPEGs, 4,300 RAW photos, or 2.5 hours of the highest-quality video. A fast 10 Gb/s USB-C port makes it easy to offload data and charge the camera.

Now, time to talk about the image quality. The BF camera features a 24MP BSI CMOS sensor—a standard for modern imaging. This sensor updates from Sigma’s past with a hybrid autofocus system that blends phase-detect and contrast-detect tech for fast, accurate focus. The camera will even record up to 6K video at up to 30p and offers L-Log for maximum dynamic range.

A powerful imaging pipeline and a streamlined design aim to deliver the simplest and most frustration-free shooting experience you can find today.

Sigma 300-600mm f/4 DG OS Sports Lens

Key Features

Full-Frame | f/4 to f/16Constant Aperture Super Telephoto ZoomHLA AF Motor5.5 Stops of Optical Stabilization28 Elements in 21 GroupsAnomalous and High-Refractive GlassWeather-Sealed Design

Sigma’s long history of lens development has a smattering of super telephoto options over the years—including only one serious prime since joining their L-Mount Alliance. They have also been known for unique offerings, such as the APO 200-500mm f/2.8 EX, which is one of the most specialized designs we have ever seen and shows photographers the answer to the oft asked question, “Why not just make everything an f/2.8 constant?” (The answer is, to anyone who knows better, a gigantic and very expensive lens.)

That all brings us to today, just days before the CP+ show in Japan, where Sigma has revealed a groundbreaking 300-600mm f/4 DG OS Sports Lens. A full-frame lens available in Sony E and L-Mount, this is an incredible zoom offering for professional photographers. Having a constant aperture for such a long focal length makes this lens competitive with primes, but with the obvious advantage of versatility—it basically offers shooters 300, 400, 500, and 600mm primes all in one package and without needing to change lenses or add a teleconverter.

This is clearly a professional lens as Sigma has packed all its advanced imaging tech into it. It is a constant f/4 aperture, and it features internal zoom to minimize weight shifts during shooting. It also has plenty of low dispersion and high-refractive index glass to minimize aberrations. Add on a high-thrust HLA autofocus motor and 5.5 stops of optical stabilization and you have a solid performer for sports, wildlife, and other distant subjects.

Operation of the lens has been enhanced with the addition of a function ring that can be set to Focus Preset or Power Focus modes. The preset option will allow you to instantly have the lens shift to a set focus position while the power focus allows for smooth focus shift at a constant speed, something ideal for video.

Befitting a large telephoto zoom, the 300-600mm features a rotating tripod socket as well as a drop-in filter holder. And, of course, it has been weather sealed.

The Sigma 300-600mm f/4 DG OS is an interesting new option for sports and wildlife photographers who want the ultimate in super telephoto versatility. And what may be the most shocking is the price. With a launch price of $5,999 Sigma managed to bring absurd value to a unique lens with little competition beyond primes that often cost many thousands more.

An Even More Versatile APS-C All-In-One: the 16-300mm

Oft maligned, the “basic” all-in-one zoom lens is a staple for photographers who want extreme versatility and no fuss—just slap this one optic on your camera and shoot anything and everything. Sigma is making their APS-C all-in-one even more “all” with the 16-300mm f/3.5-6.7 DC OS Contemporary Lens. This extends the wide end since Sigma’s last all-in-one zoom and creates an equivalent zoom range of 24-450mm. Whether it is a sweeping landscape, a gorgeous portrait, or distant wildlife, this lens will make sure you can capture it.

Available for Sony E, L-Mount, FUJIFILM X, and Canon RF systems, the 16-300mm is going to be a a versatile pick for many shooters. It’s headline 18.8x zoom range is the top feature, though a 1:2 maximum magnification ratio and up to 6 stops of optical image stabilization make it a complete package. An HLA motor also ensures speedy, accurate autofocus to complete the package.

These lenses maintain a tough balance of size, range, and price and Sigma has seemed to figure out the ideal set of features to make the 16-300mm you see today.

In HelloNation, Custom Fabrication Expert Mark Coyle Explains a Common Mistake in Custom Aluminum Design

Published

on

By

The article explains why smart geometry, not thicker walls, creates stronger, more efficient aluminum components.

ROCHESTER, N.Y., Oct. 24, 2026 /PRNewswire/ — What early design choice causes many custom aluminum projects to become heavier, costlier, or harder to manufacture? That question is addressed in a HelloNation article featuring insights from Custom Fabrication Expert Mark Coyle of American Custom Metals, Inc. in Rochester, New York, that outlines how misunderstanding aluminum behavior leads designers to rely on thick walls instead of stronger geometry.

The article begins by explaining that many people assume thicker walls automatically make aluminum parts stronger. It notes that aluminum does not respond to wall thickness the way steel does. Instead, its performance is shaped by how the metal flows through the extrusion die. The article states that custom aluminum design is more effective when profiles use ribs, chambers, and flanges to create stiffness without adding unnecessary weight. This guidance helps readers understand why adding material often increases cost without improving strength.

The article also highlights that thicker walls change how aluminum moves during extrusion. When heavy areas fill more slowly, the metal cools unevenly and can develop stress that only appears later. The HelloNation piece explains that well-balanced geometry keeps extrusion smooth and predictable. This consistency makes it easier to maintain dimensional accuracy across long production runs. By focusing on geometry, custom aluminum design avoids the problems that come with slow extrusion speeds and uneven cooling.

Another insight in the article centers on how ribs and internal supports influence stability. It describes how a thin wall supported by a properly placed rib often performs better than a thick wall with no reinforcement. This happens because the rib helps distribute load, improve stiffness, and guide the aluminum as it cools. The article explains that this structural approach makes custom aluminum design more efficient and gives designers more control over how the final part behaves under pressure.

The article also shows why early collaboration between designer and fabricator prevents costly changes. It states that a fabricator familiar with extrusion can catch potential issues before a die is built. Small adjustments to corners or transitions can remove weak points or improve metal flow. The article notes that this teamwork keeps the design aligned with real-world production. By working together early, both sides reduce the risk of redesigning the die after the first test run.

Machining is another area where the article explains how wall thickness affects performance. Features such as deep pockets or sharp internal angles may require slow feed rates or special tooling. When walls are thicker than needed, those areas can become difficult to machine cleanly. The article states that thoughtful custom aluminum design makes machining more predictable. Small changes, such as adding radiused edges or sizing features to match standard tools, help shorten cycle times and prevent tool wear.

Thermal behavior receives detailed attention as well. The article explains that aluminum retains heat differently depending on the mass of each section. Thicker walls hold heat longer, which increases the chance of distortion during extrusion, machining, or finishing. When a design uses geometry to create strength, the material cools more evenly. This reduces warping and helps long profiles stay aligned. The article notes that stable cooling is important for components that require a precise fit and consistent shape throughout an entire production run.

Cost is also a key topic in the article. It states that heavier profiles increase material use, extrusion time, and tooling needs. A custom aluminum design that relies on geometry instead of mass lowers material consumption and keeps the fabrication process efficient. The article explains that lighter parts are easier to handle, ship, and assemble. This saves money across multiple stages of production and supports long-term manufacturing efficiency.

The article also notes that smart custom aluminum design creates profiles that behave predictably during extrusion and machining. Smooth transitions, balanced wall dimensions, and structural features help reduce the chance of distortion or dimensional drift. These elements also lower scrap rates and support reliable performance. By using geometry instead of excess material, designers build parts that maintain strength without compromising manufacturability.

As the article concludes, it emphasizes that avoiding thick walls is one of the best ways to improve performance and lower cost. It states that the most dependable custom aluminum components come from designs that use structural features to strengthen the profile. When designers understand how aluminum behaves at each stage of extrusion and machining, they create parts that are strong, efficient, and consistent from batch to batch. This approach turns custom aluminum design into a predictable process rather than a series of uncertain adjustments.

A Common Mistake in Custom Aluminum Design features insights from Mark Coyle, Custom Fabrication Expert of Rochester, NY, in HelloNation.
