Price Comparison
When it comes to pricing, the SIRUI 20mm T1.8 Anamorphic Lens and the TTArtisan AF 56mm F1.8 lens differ significantly. The SIRUI lens is priced at $599.00, while the TTArtisan lens is more budget-friendly at $129.00. This means the SIRUI lens is about 367% more expensive than the TTArtisan lens. The substantial price difference reflects the SIRUI's specialized features tailored for cinematic use, whereas the TTArtisan offers a more general-purpose design suitable for everyday photography.
Lens Type and Purpose
The SIRUI 20mm lens is an anamorphic lens, designed primarily for cinematographers seeking to create cinematic visuals with a 1.33x squeeze factor, resulting in a 2.35:1 widescreen ratio. This lens is ideal for filmmakers who want to capture expansive landscapes or dramatic scenes without cropping. In contrast, the TTArtisan 56mm lens is a standard autofocus lens, suited for portrait and general photography. Its design caters to photographers wanting a soft bokeh effect, making it versatile but less specialized for cinematic applications.
Autofocus Capabilities
Both lenses incorporate advanced autofocus features, but their applications differ. The SIRUI 20mm lens utilizes a precision STM stepping motor, providing smooth and quiet autofocus with eye-tracking capabilities. This is particularly beneficial for video creators needing accurate subject focus. On the other hand, the TTArtisan AF 56mm lens also features an STM stepping motor, offering agile eye recognition focus, which enhances its performance for photography and video recording. While both lenses excel in autofocus, the SIRUI's features are tailored for cinematic use, while the TTArtisan is more suited for traditional photography.
Aperture and Low-Light Performance
The SIRUI 20mm lens boasts an ultra-fast T1.8 aperture, allowing it to excel in low-light conditions, reducing ISO requirements for clearer night scenes and enhanced depth of field control. This feature is essential for filmmakers who often shoot in varied lighting environments. Conversely, the TTArtisan 56mm lens also has a large F1.8 aperture, which is beneficial for low-light photography and achieving a soft bokeh effect. While both lenses perform well in low-light situations, the SIRUI’s wider aperture offers greater versatility for cinematic applications.
Build Quality and Design
In terms of build quality, the SIRUI 20mm lens is designed to be lightweight and compact, weighing only 480g, which makes it suitable for handheld shooting and gimbal use. Its design focuses on portability without compromising on optical quality. The TTArtisan 56mm lens features a metal barrel and mount made from aviation aluminum, enhancing its durability. However, it lacks the compactness of the SIRUI lens, which may affect mobility for users who prioritize lightweight gear. Both lenses are well-constructed but cater to slightly different user needs regarding portability and aesthetics.
Compatibility
The SIRUI 20mm lens is specifically designed for E-mount cameras including models like the A6500, A6700, and FX3/30, making it an excellent choice for users of Sony's mirrorless system who require high-quality cinematography gear. The TTArtisan 56mm lens is also compatible with a wide range of Sony E-mount cameras, including A5000, A5100, A6000 series, and others. While both lenses cater to the same camera mount, the SIRUI lens is more specialized for cinematic video work, while the TTArtisan lens serves general photography needs, making it versatile for a broader audience.
Use Cases
The use cases for these two lenses are quite distinct. The SIRUI 20mm lens is geared towards filmmakers and video creators who need a lens that delivers stunning cinematic visuals and excellent low-light performance. It is perfect for capturing landscapes, indoor scenes, and other expansive visuals with ease. In contrast, the TTArtisan 56mm lens is ideal for portrait photographers and hobbyists looking to enhance their photography with sharp images and soft backgrounds. Its versatility makes it suitable for a variety of shooting scenarios, but it does not provide the same level of cinematic quality as the SIRUI lens.
Which should you buy?
Choosing between the SIRUI 20mm T1.8 Anamorphic Lens and the TTArtisan AF 56mm F1.8 lens ultimately hinges on your specific needs. If you are a filmmaker or a videographer seeking to create high-quality cinematic content, the SIRUI lens offers unique features that justify its higher price. However, if you are a photographer looking for an affordable, versatile lens that performs well in various situations, the TTArtisan lens is an excellent choice at a significantly lower price point of $129. Each lens serves its purpose well, but the right choice will depend on whether your focus is on filmmaking or photography.
