With a 1.33x squeeze factor, this lens enhances the visual storytelling potential, allowing creators to achieve a 2.35:1 widescreen aspect ratio without cropping. Its design caters specifically to E mount cameras, ensuring compatibility with popular models like the A6500 and A7 series. This lens focuses on providing an immersive cinematic experience, which is ideal for those who prioritize creative visual expression.

Overview of the Tamron 150-500mm F/5-6.7 Lens

The Tamron 150-500mm F/5-6.7 lens is priced at $1,199.00, positioning it as a premium option for wildlife and sports photographers. This versatile zoom lens reaches an impressive 500mm on the telephoto end, perfect for capturing distant subjects. It is designed for Nikon Z mount mirrorless cameras, providing exceptional portability and high-speed autofocus thanks to its VXD linear motor. The lens’s compact form factor allows for spontaneous shooting in ultra-telephoto scenarios, making it a practical choice for users who need flexibility in their shooting conditions.

Image Quality Comparison

In terms of image quality, the SIRUI 20mm T1.8 lens delivers a stunning cinematic view with minimal distortion, leveraging its 1.33x squeeze factor for a unique aesthetic. It covers the Super 35 format and offers an ultra-fast T1.8 aperture, which aids in low-light performance and depth of field control. On the other hand, the Tamron 150-500mm lens provides remarkable edge-to-edge sharpness, controlled aberrations, and high resolving power across its entire zoom range. The BBAR-G2 coating enhances clarity and contrast, ensuring vibrant and true-to-life images. Both lenses excel in their respective categories, but the choice largely depends on the intended use—cinematic storytelling versus distant subject capture.

Autofocus Performance

The SIRUI 20mm T1.8 features a precision STM stepping motor for smooth and quiet autofocus, making it ideal for video applications where noise can be a distraction. Its eye-tracking capabilities and AF/MF switch provide users with creative control, ensuring that subjects remain in focus even during dynamic scenes. In contrast, the Tamron 150-500mm lens also boasts high-speed autofocus through its VXD mechanism, which is particularly beneficial for fast-moving subjects like wildlife. The autofocus performance in both lenses is commendable, but the SIRUI lens may have a slight edge for videographers due to its focus on silent operation.

Build Quality and Portability

The SIRUI 20mm T1.8 lens is compact and lightweight, weighing only 480g (1.06lbs), making it an excellent choice for handheld shooting and gimbal work. Its size allows for easy transport, which is crucial for those engaged in on-the-go shooting. Conversely, the Tamron 150-500mm lens, while still compact for a super-telephoto lens at 8.4 inches and extending to 11.3 inches, is heavier and bulkier than the SIRUI. However, its moisture-resistant construction and fluorine coating provide added durability, making it suitable for outdoor shooting in various weather conditions.

Versatility in Shooting Scenarios

The SIRUI 20mm T1.8 lens excels in wide-angle scenarios, perfect for capturing expansive landscapes and tight indoor spaces, making it versatile for both cinematic and photography needs. The lens’s broad perspective is ideal for storytelling through visuals, offering a horizontal field of view equivalent to a 22mm full-frame lens. In contrast, the Tamron 150-500mm lens shines in wildlife and sports photography, allowing users to quickly switch from 150mm to 500mm for a variety of shooting situations. Both lenses serve distinct purposes and excel in their respective applications, making them each versatile in different contexts.

Price Considerations

The SIRUI 20mm T1.8 is priced at $599.00, which is about 50% cheaper than the Tamron 150-500mm, which retails for $1,199.00. This significant price difference may influence the decision for budget-conscious buyers. While the SIRUI offers a more economical choice for those focused on video and wide-angle photography, the Tamron lens justifies its higher price with its extended zoom range and superior image stabilization technology. Buyers must evaluate their primary use case and budget to determine which lens offers the best value for their needs.

Which should you buy?

Choosing between the SIRUI 20mm T1.8 Anamorphic Lens and the Tamron 150-500mm F/5-6.7 lens ultimately depends on your specific photography or videography needs. If you're seeking a lens focused on cinematic quality with a wide-angle perspective, the SIRUI is a fantastic option at a reasonable price. However, if your work demands versatility in super-telephoto capabilities and you often shoot distant subjects, the Tamron might be worth the higher investment. Consider your shooting style, the types of subjects you capture, and your budget to make the best choice.
