Photographic Lens System Enabling Reduction in Tightness of Manufacturing Tolerance
A photographic lens system includes first to sixth lenses arranged sequentially from an object along the optical axis. The first lens has positive refractive power, the second lens is meniscus shaped and has negative refractive power, the third lens has an upwardly-convex shape and positive refracti...

| Zusammenfassung: | A photographic lens system includes first to sixth lenses arranged sequentially from an object along the optical axis. The first lens has positive refractive power, the second lens is meniscus shaped and has negative refractive power, the third lens has an upwardly-convex shape and positive refractive power, the fourth lens has an upwardly-convex shape and negative refractive power, the fifth lens has positive refractive power, and the sixth lens has negative refractive power. The photographic lens system satisfies −10 |
