Both lenses are designed for Sony E-mount cameras, but they cater to different photographic needs. The Sigma offers versatility with its zoom range, while the Sony provides a fast aperture ideal for low-light conditions and beautiful bokeh effects.

Design and Build Quality

When it comes to design, the Sigma 28-70mm F2.8 DG DN is renowned for its superb build quality and lightweight, compact body, making it an excellent choice for daily use. The lens incorporates internal focusing and a focus mode switch, adding functionality to its design. On the other hand, the Sony FE 35mm f/1.8 also emphasizes portability with a compact and lightweight design, setting a new standard for ease of use. Its aspherical element further enhances its optical performance while keeping the overall weight down.

Aperture and Bokeh

The Sigma 28-70mm features a constant aperture of f/2.8 throughout its zoom range, which is suitable for a variety of lighting conditions and provides good background blur. In contrast, the Sony FE 35mm offers a wider maximum aperture of f/1.8, contributing to its ability to produce gorgeous bokeh thanks to its 9-blade circular aperture. This makes the Sony particularly appealing for portrait photography and situations where depth of field control is essential.

Focusing Capabilities

Focusing capabilities differ significantly between the two lenses. The Sigma 28-70mm utilizes internal focusing technology, which is beneficial for maintaining the lens's compact size and balance. The Sony FE 35mm, however, boasts a fast and precise linear-motor autofocus system, designed to deliver quiet and accurate focusing. This makes the Sony particularly well-suited for shooting video or capturing fleeting moments where speed is crucial.

Versatility and Use Cases

In terms of versatility, the Sigma 28-70mm F2.8 DG DN stands out with its zoom range, making it suitable for various photography styles, including landscapes, portraits, and events. The 28-70mm range allows for flexibility in composing shots without needing to change lenses frequently. Conversely, the Sony FE 35mm f/1.8 excels in scenarios where low-light performance and subject isolation are critical, such as indoor events or street photography.

Price and Value

The Sigma 28-70mm F2.8 DG DN is priced at $859.95, while the Sony FE 35mm f/1.8 comes in at $798.00. This price difference of about $61 makes the Sony a more budget-friendly option for photographers who may prioritize affordability without sacrificing quality. Both lenses offer excellent value, but the choice may depend on whether you prefer the versatility of a zoom lens or the low-light capabilities of a prime lens.

User Experience

User experience plays a significant role in selecting a lens. The Sigma 28-70mm's focus mode switch allows for quick adjustments during shooting, which is beneficial for dynamic situations. The build quality also adds to its usability, making it a reliable companion for day-to-day photography. On the other hand, the compact nature of the Sony FE 35mm f/1.8 makes it an ideal choice for travel and street photography, where weight and size can impact the shooting experience. Both lenses have their strengths, but user preference will ultimately guide the decision.

Which should you buy?

Choosing between the Sigma 28-70mm F2.8 DG DN and the Sony FE 35mm f/1.8 boils down to your specific photography needs and budget. If you need versatility and the flexibility of a zoom lens, the Sigma is the better option despite its higher price. However, if you prefer a prime lens that excels in low-light scenarios and delivers beautiful bokeh, the Sony is a fantastic choice at a lower price point. Ultimately, both lenses offer excellent quality and performance, catering to different styles and preferences in photography.
