Price Comparison
The SIRUI 20mm T1.8 Anamorphic Lens is priced at $599.00, while the TTArtisan AF 27mm F2.8 lens is significantly cheaper at $159.99. This makes the TTArtisan lens about 73% more affordable than the SIRUI lens. For budget-conscious photographers and videographers, this price difference is substantial, allowing for more flexibility in purchases. However, the SIRUI lens targets a different market segment, focusing on high-end cinematic capabilities and offering features that justify its higher price.
Target Audience
The SIRUI 20mm T1.8 lens is designed primarily for cinematographers and video creators looking for a cinematic experience with its anamorphic capabilities. Its 1.33x squeeze factor allows for immersive widescreen visuals, ideal for producing films and high-quality video content. In contrast, the TTArtisan AF 27mm F2.8 lens caters to Fujifilm camera users, specifically those shooting street photography, portraits, or everyday scenes. Its compact size and affordability make it an excellent choice for casual photographers and travelers who want a reliable lens without breaking the bank.
Features and Performance
The SIRUI 20mm T1.8 lens boasts a wide T1.8 aperture, enhancing low-light performance and allowing for stunning bokeh effects. Its STM stepping motor provides smooth and accurate autofocus, crucial for capturing fast-moving subjects in video. Meanwhile, the TTArtisan AF 27mm F2.8 lens features an independent click aperture ring and a closest focusing distance of 0.35 m, making it versatile for detailed close-up shots. While both lenses offer autofocus capabilities, the SIRUI lens is tailored for cinematic quality, whereas the TTArtisan lens excels in everyday photography scenarios.
Compatibility
The SIRUI 20mm lens is optimized for E-mount cameras, including popular models like the Sony A6500 and A7 series. This makes it an attractive choice for users of Sony's mirrorless camera lineup. Conversely, the TTArtisan AF 27mm lens is designed for Fujifilm's X-mount cameras, compatible with a wide range of models such as the X-T10 and X-T4. If you already own a camera from one of these brands, your lens choice is somewhat predetermined by your existing gear.
Size and Weight
Weighing in at 480g (1.06 lbs), the SIRUI 20mm lens is relatively compact for an anamorphic lens but may still feel hefty compared to the TTArtisan AF 27mm, which is likely lighter given its smaller size and simpler construction. The compactness of the TTArtisan lens makes it an attractive option for on-the-go shooting, especially for street photographers and travelers who prioritize portability. The SIRUI lens, while not excessively heavy, is designed for more stable shooting setups, often requiring a tripod or gimbal for optimal performance.
Autofocus and Usability
The SIRUI 20mm T1.8 lens features advanced autofocus capabilities, including eye-tracking and an AF/MF switch, providing creatives with greater control. Its focus system is ideal for dynamic video shooting, ensuring subjects remain in focus even during movement. On the other hand, the TTArtisan AF 27mm lens also employs a reliable STM motor for smooth autofocus and includes eye detection for tracking subjects, which is beneficial for portrait photography. Both lenses prioritize user-friendliness, but the SIRUI lens's features cater more to cinematic applications, while the TTArtisan lens is designed for straightforward photography tasks.
Image Quality
The SIRUI 20mm T1.8 lens promises excellent image quality with its ability to deliver a 2.35:1 widescreen ratio without cropping, enhancing the cinematic feel of videos. Its optimized image circle for APS-C and Super 35 sensors ensures clarity and coverage. The TTArtisan AF 27mm F2.8 lens, while not as specialized, still offers excellent image quality for everyday photography, featuring a large aperture that contributes to good bokeh and sharp details. However, for those seeking the highest quality cinematic visuals, the SIRUI lens stands out significantly.
Which should you buy?
Ultimately, your choice between the SIRUI 20mm T1.8 Anamorphic Lens and the TTArtisan AF 27mm F2.8 lens should be guided by your specific needs and budget. If you are a videographer aiming for cinematic quality and are willing to invest in a higher-priced lens, the SIRUI lens is an excellent option. However, if you are a Fujifilm user looking for a lightweight, affordable lens for everyday photography, the TTArtisan lens would serve you well. The differences in price, features, and target audience make both lenses suitable for distinct purposes, ensuring that each has its place in a photographer's toolkit.
