With a price tag of $419.00, this lens is positioned as a premium option for serious photographers. It boasts a large aperture of F1.4, making it excellent for low-light conditions and depth of field control. The stepping motor provides fast and accurate autofocus, making it suitable for both photography and video work.

Overview of Viltrox 25mm F1.7 E

The Viltrox 25mm F1.7 E is a budget-friendly alternative, priced at $176.00, which makes it about 58% cheaper than the Sigma lens. Despite its lower price, it still offers a bright maximum aperture of F1.7, suitable for low-light environments and depth of field management. Weighing in at only 170g, the Viltrox is designed for portability, making it an excellent choice for travel and everyday use.

Image Quality

When it comes to image quality, the Sigma 30mm F1.4 is designed for APS-C Mirrorless cameras and is part of Sigma's Contemporary line, which is known for its high-quality optics. The nine rounded aperture blades help create attractive bokeh, enhancing the overall image aesthetic. The Viltrox 25mm F1.7, while not as renowned, still utilizes a bright aperture that allows for decent image quality and depth of field control. However, it may not reach the same level of optical performance as the Sigma.

Autofocus Performance

Autofocus is a critical aspect for many photographers, and both lenses offer distinct advantages. The Sigma 30mm features a stepping motor that ensures fast and accurate autofocus, making it particularly effective for video recording. In comparison, the Viltrox 25mm also adopts an STM stepper motor, providing a quiet autofocus experience, which is beneficial for both photo and video shooting. However, the Sigma may have the edge in speed and accuracy due to its design focus on performance.

Build and Design

In terms of build and design, the Sigma lens is compact and portable, making it easy to carry around. It includes essential accessories like a lens hood, rear, and front cap, enhancing its usability. The Viltrox, weighing only 170g, is even lighter, further enhancing its travel-friendly attributes. While both lenses are designed for portability, the Viltrox may appeal more to those needing a lightweight option for everyday use.

Compatibility

The Sigma 30mm F1.4 is compatible with a wide range of Sony E-mount cameras, including various APS-C models. This makes it a versatile choice for users who own multiple Sony cameras. The Viltrox 25mm F1.7 is also compatible with most Sony E-mount mirrorless cameras, including high-end models like the a7 series. Both lenses support face and eye recognition autofocus, making them adept for portrait photography.

Price Comparison

In terms of pricing, the Sigma 30mm F1.4 is priced at $419.00, while the Viltrox 25mm F1.7 is available for $176.00. This represents a significant price difference of about $243, making the Viltrox a more accessible option for budget-conscious photographers. However, the higher price of the Sigma lens reflects its premium build quality and optical performance, which may justify the investment for serious users.

Which should you buy?

Ultimately, the decision between the Sigma 30mm F1.4 Contemporary DC DN Lens and the Viltrox 25mm F1.7 E depends on your specific needs and budget. If you prioritize high optical performance and are willing to invest more, the Sigma lens is an excellent choice. However, if you're looking for a lighter, budget-friendly option that still offers good low-light performance, the Viltrox is worth considering. Both lenses have their strengths, so your choice should align with your photographic goals and budget constraints.
