What is the Sigma 135mm f/1.8 Art Lens?
The Sigma 135mm f/1.8 DG HSM Art lens is a professional-grade telephoto prime lens designed for full-frame cameras. As part of Sigma’s esteemed Art series, it prioritizes exceptional optical performance, build quality, and overall image rendering. The “135” signifies its focal length in millimeters, while “f/1.8” indicates its incredibly wide maximum aperture. This combination results in stunningly sharp images, beautiful bokeh (background blur), and excellent low-light capabilities. It’s a lens favored by professionals and serious amateurs alike.
History and Evolution of the 135mm Focal Length
The 135mm focal length has a rich history in photography. Originally designed for rangefinder cameras, it quickly gained popularity as a versatile telephoto option for various genres, including portraiture and street photography. The 135mm focal length offers a compressed perspective compared to wider lenses, making it ideal for isolating subjects and creating a sense of intimacy. Sigma’s modern interpretation builds upon this legacy with cutting-edge optical technology and advanced features.
Understanding Aperture and its Impact
The f/1.8 aperture is a crucial aspect of the 135 sigma 1.8. A wide aperture allows more light to enter the lens, enabling faster shutter speeds in low-light conditions. This is particularly valuable for capturing action shots or shooting in dimly lit environments. Furthermore, the wide aperture creates a shallow depth of field, resulting in a blurred background that beautifully isolates the subject. This effect, known as bokeh, is highly sought after in portrait photography.
The Sigma Art Series: A Commitment to Excellence
Sigma’s Art series represents the pinnacle of their lens design and manufacturing capabilities. These lenses are meticulously crafted to deliver exceptional image quality, optical performance, and overall user experience. The 135 sigma 1.8 is a prime example of this commitment, showcasing advanced optical elements and innovative technologies.
Key Features of the Art Series
- Exceptional Optical Performance: Art lenses are designed to minimize aberrations, distortions, and other optical imperfections.
- Robust Build Quality: These lenses are built to withstand the rigors of professional use.

Detailed Feature Analysis of the Sigma 135mm f/1.8
The 135 sigma 1.8 is packed with features that contribute to its exceptional performance. Let’s delve into some of the key elements:
1. Super Multi-Layer Coating
What it is: Sigma’s Super Multi-Layer Coating is applied to the lens elements to minimize flare and ghosting. These unwanted artifacts can degrade image quality, especially when shooting in challenging lighting conditions.
How it works: The coating reduces reflections on the lens surfaces, allowing more light to pass through and improving contrast and color accuracy.
User Benefit: Sharper, clearer images with reduced flare and ghosting, even in bright sunlight or backlit situations. This is particularly important for maintaining image quality in high-contrast scenes.
2. Hyper Sonic Motor (HSM)
What it is: The HSM provides fast, quiet, and accurate autofocus performance. This is crucial for capturing sharp images of moving subjects or working in situations where silence is essential.
How it works: The HSM uses ultrasonic vibrations to drive the autofocus mechanism, resulting in smooth and responsive focusing.
User Benefit: Reliable and precise autofocus, allowing you to quickly and accurately capture your desired subject. This is especially beneficial for portrait, sports, and wildlife photography.
3. Floating Focus System
What it is: A floating focus system adjusts the position of the lens elements during focusing to maintain optimal image quality at all distances, including close-up subjects.
How it works: This system compensates for aberrations that can occur when focusing at different distances, ensuring consistent sharpness and clarity.
User Benefit: Consistently sharp images, even when shooting close-ups. This feature enhances the lens’s versatility and makes it suitable for a wider range of subjects.
4. Nine-Blade Rounded Diaphragm
What it is: The nine-blade rounded diaphragm creates a smooth and pleasing bokeh effect. This is highly desirable for portrait photography, where a blurred background helps to isolate the subject.
How it works: The rounded blades maintain a circular aperture shape, even when stopped down, resulting in smoother and more natural-looking bokeh.
User Benefit: Beautifully blurred backgrounds that enhance the aesthetic appeal of your images. The smooth bokeh creates a sense of depth and isolation, drawing the viewer’s attention to the subject.
5. Thermally Stable Composite (TSC) Material
What it is: Sigma uses TSC material in the lens barrel to provide consistent performance in a wide range of temperatures. This material is less susceptible to expansion and contraction than traditional plastics, ensuring that the lens maintains its optical alignment.
How it works: TSC material minimizes the impact of temperature changes on the lens’s internal components, preventing distortion and maintaining image quality.
User Benefit: Reliable performance in various environmental conditions. The lens maintains its optical integrity, even when subjected to extreme temperatures.
6. Dust and Splash-Proof Construction
What it is: The lens features a dust and splash-proof design, making it suitable for use in challenging environments. This construction protects the internal components from moisture and debris, ensuring reliable performance in adverse conditions.
How it works: Seals and gaskets are strategically placed throughout the lens to prevent the ingress of dust and moisture.
User Benefit: Increased durability and reliability, allowing you to shoot with confidence in various weather conditions. This feature is particularly valuable for outdoor photographers who frequently encounter dust, rain, or snow.
7. Compatible with Sigma USB Dock
What it is: The lens is compatible with the Sigma USB Dock, which allows you to customize the lens’s autofocus performance and update its firmware.
How it works: The USB Dock connects the lens to your computer, allowing you to adjust parameters such as autofocus speed and accuracy.

Insightful Q&A Section
-
Q: What is the optimal focusing technique for achieving tack-sharp images with the Sigma 135mm f/1.8, especially when shooting portraits at f/1.8?
A: When shooting portraits wide open at f/1.8, critical focus is paramount. Utilize your camera’s eye-detection autofocus mode if available. Otherwise, use single-point AF and carefully place the focus point on the subject’s eye. Consider using focus peaking in live view for manual focus fine-tuning.
-
Q: How does the Sigma 135mm f/1.8 perform for astrophotography, and what are the recommended settings for capturing detailed images of the night sky?
A: The 135 sigma 1.8 is excellent for astrophotography due to its wide aperture and sharp optics. Use a low ISO (e.g., ISO 800-1600), a wide aperture (f/1.8 or f/2), and a long exposure time (e.g., 15-30 seconds) depending on your camera and the amount of light pollution. Use a sturdy tripod and consider using a star tracker for longer exposures.
-
Q: What are the best accessories to complement the Sigma 135mm f/1.8, such as filters or lens hoods, to enhance its performance and protect it from the elements?
A: A high-quality UV filter can protect the front element of the lens. A circular polarizer can reduce glare and enhance colors. The included lens hood is essential for preventing flare and ghosting. A padded lens case can protect the lens during transport.
