The ultimate 135mm telephoto lens with optical performance as a priority.

The 135mm focal length has a strong perspective compression effect, while the F1.8 speed delivers great bokeh. By minimizing longitudinal chromatic aberration, the SIGMA 135mm F1.8 DG HSM Art's bokeh is as impressive as it is beautiful, and the lens delivers shots with excellent contrast as well as outstanding sharpness.

It offers the outstanding resolution required for DSLRs with 50 megapixels or more. By incorporating the latest innovations in design and optical glass, and rethinking every aspect of the lens, we ensure outstanding image quality across the entire image range and set new standards for 135mm telephoto lenses.

With resolution so crystal clear that every hair in a portrait is discernible, this large diameter lens also delivers stunning bokeh , giving photographers everything they need.

It's ideal for close-ups and full-body shots, setting off the subject against a pleasantly blurred background. In addition to standard portraits, including wedding photography, this lens brings top performance to live events and captures subjects effortlessly with its super-fast autofocus.

Design

To deliver the ultra-high resolution that brings out the best in DSLRs with 50 megapixels or more, the focus mechanism features SIGMA's floating system. Regardless of the distance to the subject, this lens delivers top performance from the center of the frame to the edges. The lens design also minimizes distortion to deliver flawless image quality, eliminating the need for digital adjustments during image processing.

Ideal for portraits that require impressive bokeh.

The 135mm focal length delivers an impressive compression effect: even with a comparatively close subject, the telephoto allows the photographer to create a variety of dramatic perspectives. The compression effect shines in both close-ups and full-length portraits, making image composition easier.

Even more, the F1.8 speed creates full-body portraits with stunning background bokeh. All in all, this lens gives photographers a full range of compositional options.

Fast and reliable autofocus photography.

The large Hyper-Sonic Motor (HSM) provides ample torque to the focusing group for superior speed, while ensuring exceptionally consistent performance even at low speeds. Together with the optimized AF algorithm, these features ensure fast autofocus photography. In addition, the focus range limiter lets the AF respond very accurately to the distance to the subject, making performance even more reliable.

The mount is dust and splash resistant

Since the mount of a lens is particularly susceptible to dust and other foreign objects, this lens has been designed with rubber sealing to prevent dirt from entering. The front lens element also has a water- and oil-repellent coating, so the lens can be used well in the rain, near water, or in other difficult conditions.

Additional benefits

Sigma USB dock

With this USB dock, the new SIGMA lenses of the Contemporary, Art and Sports product series can be adapted to the personal needs of each photographer. For this purpose, we have developed a special software (SIGMA Optimization Pro) that allows you to easily update the lens firmware and adjust focus parameters, for example.

Sigma Connection change service

We offer our customers our connection exchange service for a fee. Within the scope of this service, we modify the mount of the lenses of the Contemporary, Art and Sports product lines by replacing all relevant parts according to customer requirements.

Own A1 MTF measuring system

We have our own A1 MTF (Modulation Transfer Function) measurement system that uses the 46-megapixel Foveon direct image sensor. Using this system, we inspect every lens in our new product line at our factory. Even previously undetectable high-frequency details have now become testable as part of our quality control process, which allows us to deliver consistently high lens performance.

Made in Japan

We are focused on optimizing quality with our integrated production system, using our own hands and techniques. We are one of the few manufacturers whose products are exclusively "Made in Japan". We are proud of the authentic quality of SIGMA products as the result of a combination of highly specialized expertise and intelligent modern technology.
