Sigma vs TTArtisan

Price Comparison

The Sigma 30mm F1.4 Contemporary DC DN Lens is priced at $419.00, while the TTArtisan 40mm F2 L is significantly cheaper at $168.00, making it about 60% less expensive. This substantial price difference may appeal to budget-conscious photographers or those just starting in photography. The Sigma lens offers a larger maximum aperture of F1.4, which is ideal for low-light conditions and providing depth of field. In contrast, the TTArtisan lens, with its F2 aperture, is still quite competent for general photography but does not match the low-light performance of its competitor.

Brand Reputation

Sigma is a well-established brand in the photography world, known for producing high-quality lenses that are often favored by professionals. The Sigma 30mm lens is part of the Contemporary series, which emphasizes a balance between performance and compactness. On the other hand, TTArtisan is a newer brand that has gained popularity for offering affordable alternatives without compromising on quality. While both brands have their merits, Sigma's long-standing reputation may sway photography enthusiasts who prioritize trusted brands over cost.

Build Quality and Design

The Sigma 30mm lens is designed to be compact and lightweight, making it a practical choice for on-the-go photography. It features nine rounded aperture blades and a stepping motor for fast and accurate autofocus, enhancing its usability for video work. The TTArtisan 40mm lens, while also compact and lightweight (weighing between 167-176g), incorporates ED and aspherical elements to control chromatic aberration effectively. Both lenses are designed with portability in mind, but the Sigma may have an edge in build quality due to its handcrafted nature in Japan.

Autofocus Performance

Autofocus performance is crucial for capturing sharp images quickly. The Sigma 30mm lens employs a stepping motor, which allows for fast and precise focusing, making it well-suited for both still photography and video. Meanwhile, the TTArtisan 40mm lens also features a stepping motor for quiet and efficient autofocus. While both lenses offer reliable autofocus, the Sigma’s reputation for superior autofocus performance may appeal to videographers or photographers who require quick and accurate focusing in dynamic settings.

Image Quality

When it comes to image quality, the Sigma 30mm F1.4 lens is designed to deliver high performance with a large aperture that excels in low-light conditions. It is crafted to provide exceptional image quality, particularly because it is a part of Sigma’s Art line, which focuses on outstanding optical performance. The TTArtisan 40mm lens, with its combination of ED and aspherical elements, also promises excellent image quality, effectively controlling chromatic aberration while maintaining clarity. While both lenses are capable of delivering good results, the Sigma might have a slight advantage due to its larger aperture and reputation for superior optical performance.

Versatility

The Sigma 30mm lens is versatile enough for various photography styles, from portraits to landscapes, thanks to its effective focal length on APS-C cameras. Its large aperture allows for creative depth of field effects, making it suitable for various artistic expressions. The TTArtisan 40mm lens, with its versatile 40mm focal length, is ideal for street, travel, and documentary photography, balancing environmental context with subject isolation. Both lenses cater to different styles, but the Sigma may be more appealing for those who prioritize low-light shooting and portraiture.

Compatibility

The Sigma 30mm F1.4 lens is specifically designed for Sony E-mount cameras, making it an excellent choice for users within that ecosystem. It is compatible with a wide range of Sony cameras, including various models from the a-series. In contrast, the TTArtisan 40mm F2 L is compatible with L-mount system cameras, such as the Sigma FP and Panasonic S series. This makes the TTArtisan lens more versatile in terms of camera compatibility, appealing to photographers who use various camera brands within the L-mount system.

Which should you buy?

Choosing between the Sigma 30mm F1.4 Contemporary DC DN Lens and the TTArtisan 40mm F2 L depends on your specific needs and budget. If you prioritize image quality, low-light performance, and have the budget for it, the Sigma lens is the better choice, offering excellent optical performance and fast autofocus. However, if you are looking for a more budget-friendly option that still delivers solid performance for general photography, the TTArtisan lens is a commendable choice. Ultimately, both lenses cater to different photographer needs, so consider what features are most important to you before making a decision.
