To avoid duplicates of the same camera or lens appearing in names with different word orders or formats, please use the existing names whenever available. For new entries, please follow these conventions:
- Lens Names:
- Record lens names exactly as they appear on the lens barrel.
- For example, if the lens barrel reads "Nikon AF-S 50mm f/1.4", use that exact name.
- Focal Length and Aperture:
- Convert focal length to the XXmm format (e.g., 50mm, 85mm).
- Express maximum aperture as f/x.x (e.g., f/1.4, f/2.8).
- Example: "50mm f/1.4" or "18-55mm f/3.5-5.6".
- Generations:
- Mark second, third, fourth, etc., generations with Roman numerals (II, III, IV, V, etc.).
- For instance, "Canon EF 85mm f/1.2L USM II" indicates the second generation.
- Omit "Mark":
- When referring to different versions, omit the word "Mark".
- Example: "Canon EF 85mm f/1.2L USM II" instead of "Mark II".
Follow these guidelines to maintain consistency and clarity in lens naming. 😊
