Price Comparison
The Sigma 30mm F1.4 Contemporary DC DN Lens for Sony E is priced at $419.00, while the TTARTISAN AF 27mm f2.8 APS-C Frame Lens is significantly lower at $159.99. This makes the TTARTISAN lens about 62% cheaper than the Sigma option. For budget-conscious photographers or those just starting out, the lower price point of the TTARTISAN lens may be more appealing. However, the price difference also reflects varying features and performance capabilities, which are important to consider when making a purchasing decision.
Design and Portability
When it comes to design, the TTARTISAN AF 27mm f2.8 is an ultra-compact pancake lens, making it exceptionally portable and easy to carry. This compact design is particularly beneficial for travelers and those looking to create without the burden of heavy equipment. On the other hand, the Sigma 30mm lens, while still relatively compact, is not as lightweight or small as the TTARTISAN. Its design includes nine rounded aperture blades and a stepping motor, adding to its functionality but also to its bulk. Photographers seeking a lens that can easily fit into a bag or pocket may find the TTARTISAN more suitable.
Optical Performance
The Sigma 30mm F1.4 boasts a large aperture of F1.4, which allows for excellent low-light performance and the ability to create a beautiful depth of field. This is particularly advantageous for portrait photography or any situation where background blur is desired. The TTARTISAN AF 27mm f2.8, while offering a decent aperture, is limited to F2.8. This means it may not perform as well in low-light conditions compared to the Sigma lens. Photographers who prioritize optical performance, especially in challenging lighting situations, may prefer the Sigma for its superior aperture capability.
Autofocus Technology
The Sigma lens employs a stepping motor that provides fast and accurate autofocus, beneficial for both photography and video work. This feature is especially important for videographers who require smooth focusing transitions. Conversely, the TTARTISAN lens also includes a stepping motor but emphasizes its eye recognition focus, which aids in tracking subjects more effectively. While both lenses offer advanced autofocus capabilities, the Sigma may edge out slightly in terms of overall speed and versatility, especially in dynamic shooting scenarios.
Compatibility
The Sigma 30mm F1.4 is specifically designed for Sony E-mount cameras, making it an excellent choice for users of that system. It is compatible with a wide range of Sony APS-C mirrorless cameras, ensuring versatility across different models. The TTARTISAN AF 27mm f2.8 is designed for Fuji X mount cameras, including popular models like the X-E4 and X-T3. Thus, the choice between these two lenses will largely depend on the camera system you currently own or plan to acquire. Compatibility is a critical factor, as using a lens designed for your specific mount will guarantee optimal performance.
Additional Features
The TTARTISAN lens includes unique features such as an independent clicked aperture ring, enhancing the shooting experience by allowing quick adjustments without the need to navigate through camera menus. It also boasts a USB-C interface for firmware upgrades, which is a thoughtful addition for users looking to maintain their lens performance over time. In contrast, the Sigma lens focuses on image quality and performance, including a lens hood and front and rear caps as accessories. While both lenses offer valuable features, the TTARTISAN’s additional conveniences may appeal to users looking for a more hands-on shooting experience.
User Experience and Reviews
While specific sales rankings are not provided, user experiences and reviews can often shed light on the real-world performance of these products. The Sigma 30mm lens is known for its high-quality image output and reliability, which makes it a favorite among serious photographers. The TTARTISAN AF 27mm, being budget-friendly, has garnered attention for its portability and ease of use, particularly among casual shooters and those new to photography. The choice between these two lenses may ultimately depend on the user's experience level and their specific photography needs.
Which should you buy?
Ultimately, the choice between the Sigma 30mm F1.4 Contemporary DC DN Lens and the TTARTISAN AF 27mm f2.8 comes down to specific needs and preferences. If you prioritize optical performance, low-light capabilities, and fast autofocus, the Sigma lens is likely the better investment despite its higher price tag of $419.00. However, if budget is a primary concern or if you require a lightweight, travel-friendly option, the TTARTISAN lens at $159.99 offers excellent value and adequate performance for everyday photography. Each lens has its strengths, making them suitable for different types of photographers.
