Optics 2.0X High Definition Telephoto Conversion Lens - Tighten

Our review of the Optics 2.0X High Definition Telephoto Conversion Lens focuses on what matters most: adding reliable reach to a compatible Canon PowerShot SX520 HS without breaking the bank. This conversion lens is aimed at hobbyists and event shooters who need a simple way to tighten distant subjects for sports, wildlife, or scenic detail. The single biggest reason to buy is straightforward: it multiplies focal reach with all-glass, multicoated optics and a threaded front that accepts filters, delivering sharper telephoto framing than digital crop alone.

Key Features

• 2.0X telephoto conversion: Doubles the effective focal length of the camera for closer framing of distant subjects without changing the camera body.
• All-glass multicoated optics: Reduces reflections and improves contrast for clearer detail in mid- to long-range shots.
• Threaded front element: Accepts common lens filters so shooters can add polarizers or ND filters for creative control.
• Extreme-speed autofocus support: Designed to maintain fast AF response on the compatible PowerShot model for action and event photography.
• Lens adapter ring included: The package includes an adapter ring so the conversion lens mounts cleanly to the camera without extra purchases.
• Complete starter kit: Ships with lens cap, bottom cover, and a soft pouch for transport and protection in the field.

Who It's For

This conversion lens is best for Canon PowerShot SX520 HS owners who want a low-cost way to extend reach for sports, travel, or backyard wildlife without swapping to an interchangeable-lens camera. Enthusiast photographers who value portability and a simple add-on will appreciate the included adapter ring and filter threading.

It is not aimed at pro shooters who require interchangeable lenses with full manual controls or the absolute best optical performance under all conditions. Users needing extreme low-light performance or wider aperture control should consider native telephoto lenses or larger-sensor systems instead.

Pros & Cons

Pros

• Simple 2.0X reach increase that makes distant subjects more usable without camera modification.
• All-glass, multicoated optics that help preserve contrast and reduce flare compared with cheaper plastic optics.
• Threaded front accepts filters, expanding creative options like polarization and neutral density control.
• Includes adapter ring and protective caps for immediate use and safe transport.

Cons

• As a conversion lens, ultimate sharpness and low-light speed are limited by the host camera and adapter interface.
• Performance depends on proper mounting and the camera's native autofocus, so results may vary by shooting conditions.
