objektiivide

Objektiivide is the Estonian genitive plural form of objektiiv, meaning “of lenses” or “lenses.” In Estonian grammar, this form appears in phrases such as objektiivide kvaliteet (the quality of lenses) or objektiivide optika (the optics of lenses). The term is a grammatical construction rather than a separate concept, but it is common in discussions of lenses in Estonian.

A lens (objektiiv) is an optical component that gathers and focuses light to form an image. Used in cameras, telescopes, and microscopes, lenses can consist of a single element or multiple elements made of glass or plastic. Key properties include focal length, which determines field of view and magnification; and aperture, which controls light intake and depth of field. Modern lenses often include coatings to reduce reflections and improve contrast, and may incorporate elements designed to correct aberrations.

Lens types include prime (fixed focal length) and zoom (variable focal length) designs. Specialized classifications cover macro, wide-angle, telephoto, and fisheye lenses. The choice of lens affects image perspective, depth of field, and compatibility with camera mounts. Ongoing advances in optical design and coating technology continue to improve sharpness, color accuracy, and resistance to flare.

In imaging practice, the term objektiivide may appear when referring to the lenses themselves, their performance, or their role within a system. Knowledge of this form helps in reading and translating technical photography and optics material in Estonian.
