SIRUI vs Tamron 70-

Overview

When it comes to choosing between the SIRUI 20mm T1.8 Anamorphic Lens and the Tamron 70-180mm F/2.8 Di III VC VXD G2, both offer unique features suited for different types of photography and videography. The SIRUI lens is positioned at $599.00, while the Tamron lens is priced at $999.00, making the SIRUI about 40% cheaper. Understanding their key features will help you decide which lens fits your needs better.

Design and Build Quality

The SIRUI 20mm T1.8 boasts a compact and lightweight design, weighing only 480g (1.06 lb), making it an excellent choice for handheld shooting and gimbal use. In contrast, the Tamron 70-180mm weighs 30.2 oz, which is significantly heavier and less portable. While both lenses are well-constructed, the SIRUI's smaller form factor is beneficial for creators who prioritize mobility. However, the Tamron includes moisture-resistant construction and a fluorine coating, which can enhance durability in challenging conditions.

Optical Performance

The SIRUI 20mm T1.8 features a 1.33x squeeze factor, delivering a cinematic 2.35:1 widescreen ratio, ideal for those looking to create immersive video content. Its T1.8 ultra-fast aperture allows for stunning low-light performance and soft bokeh. On the other hand, the Tamron 70-180mm, with a constant F/2.8 aperture, offers versatility across its zoom range but lacks the specialized cinematic characteristics of the SIRUI. For photographers primarily concerned with traditional photography, the Tamron's optical design is geared towards delivering high image quality across its entire zoom range.

Autofocus Capabilities

Both lenses feature advanced autofocus systems, but they cater to different needs. The SIRUI 20mm uses a precision STM stepping motor for smooth and quiet autofocus, with eye-tracking capabilities that are especially useful for video creators. Conversely, the Tamron 70-180mm employs a VXD linear motor focus mechanism, allowing for high-speed and high-precision autofocus, which excels in subject tracking. If your focus is primarily on video production, the SIRUI may offer an edge, while the Tamron would be more suited for dynamic, fast-paced photography.

Versatility in Use

The SIRUI 20mm is optimized for APS-C and Super 35 sensors, making it particularly well-suited for cinematic applications and wide-angle shots. It provides a horizontal field of view equivalent to a 22mm full-frame lens, ideal for landscapes and tight indoor spaces. On the other hand, the Tamron 70-180mm offers a versatile zoom range from 70mm to 180mm, making it ideal for a broader range of photography styles, from portraits to wildlife. If you need a lens that adapts to various shooting scenarios, the Tamron is likely the better choice.

Special Features

The SIRUI lens stands out with its unique anamorphic capabilities and T1.8 aperture, which contribute to its cinematic aesthetic. It also allows for selectable manual and autofocus, giving users creative control. Meanwhile, the Tamron lens features VC Image Stabilization, which is crucial for reducing camera shake, especially at longer focal lengths. It also supports the TAMRON Lens Utility apps, enhancing customization options for users. Each lens has its special features, but the choice depends on whether you prioritize cinematic effects or stabilization and versatility.

Price Comparison

The SIRUI 20mm Anamorphic Lens is priced at $599.00, while the Tamron 70-180mm is priced at $999.00, making the latter about 67% more expensive. For budget-conscious creators or those just starting, the SIRUI offers significant savings without compromising on quality, especially for those focused on cinematography. Conversely, the Tamron's higher price reflects its advanced features and versatility, appealing to professionals who require a more comprehensive zoom range.

User Experience and Reviews

While we don't have specific sales or bestseller ranks, both products cater to different segments of the photography and videography markets. The SIRUI lens is likely favored by independent filmmakers and content creators seeking a cinematic look, while the Tamron lens appeals more to photographers needing high-quality zoom capabilities and stabilization for still images. User reviews often highlight the SIRUI's weight and compactness as advantages for traveling creators, while the Tamron is praised for its optical quality and autofocus performance.

Which should you buy?

Choosing between the SIRUI 20mm T1.8 Anamorphic Lens and the Tamron 70-180mm F/2.8 largely depends on your specific needs. If you're focused on cinematic videography and require a lightweight, affordable lens, the SIRUI is an excellent choice at $599. However, if you need a versatile lens for a variety of photography styles and are willing to invest more for advanced features like stabilization and a broader zoom range, the Tamron at $999 might be the better option for you.
