objektivem

Objektivem is the instrumental singular form of the Czech noun objektiv, which means a lens or objective in optical devices such as cameras, microscopes, and telescopes. The term denotes the optical component that focuses light to form an image on a sensor or on film and is a basic term in discussions of photography and optics.

Grammatical notes: Objektivem is used when the lens functions as the instrument or means by which an action is performed, or after prepositions that require the instrumental case. For example: Kamera s objektivem 50 mm poskytuje ostrý obraz. The form is one of the instrumental forms of the noun objektiv that Czech uses in appropriate contexts.

Origin and cognates: The Czech objektiv originates from the German Objektiv, reflecting shared terminology in optics. Its usage parallels related terms in other European languages for optical components. In Czech, objektiv can refer to the camera lens or to the objective lens in microscopes and telescopes, with objektivem serving as the instrumental form in sentences.
