1. The Focal Length Math Contradiction

• The Problem: The sheet lists two entirely different 35mm equivalent focal lengths. Under Features, it says 35mm Equivalent Focal Length: 28.8-56mm. Under Overview, it says it translates to 27mm-52.5mm on 35mm camera.

• The Physics: Both numbers cannot be true for the same lens mount. The crop factor for a Canon APS-C sensor is 1.6x ($18\text{mm} \times 1.6 = 28.8\text{mm}$; $35\text{mm} \times 1.6 = 56\text{mm}$). The crop factor for Nikon and Sony APS-C sensors is 1.5x ($18\text{mm} \times 1.5 = 27\text{mm}$; $35\text{mm} \times 1.5 = 52.5\text{mm}$). Because the specification explicitly lists the Canon EF Lens Mount, the 1.5x Nikon calculation is completely wrong.

• The Fix: Delete 27mm-52.5mm from the overview section. Keep the accurate Canon calculation: 28.8–56mm.

2. Contradictory Aperture Terminology

• The Problem: Under Features, it is listed as a Fast Constant Maximum Aperture.

• The Terminology Nuance: While it is incredibly fast (f/1.8), a zoom lens cannot have a constant maximum aperture if the features list the aperture range as f/1.8-16. A variable aperture lens would change its maximum brightness as you zoom (e.g., f/3.5–5.6). This lens stays at f/1.8 across the entire zoom range.

• The Fix: To prevent consumer confusion, change the Aperture Range spec to Maximum Aperture: f/1.8 | Minimum Aperture: f/16.

3. Missing Structural Filter Diameter

• The Problem: Photographers buying a high-end lens need to know what size filters (polarizers, ND filters) to buy. The specification sheet completely leaves out the physical filter thread size.

• The Fix: Add a specification row for Filter Thread Diameter: 72 mm.
