Summary

[edit]
Description
English: A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image.
فارسی: لنز چشم‌ماهی لنزهایی هستند که حداکثر زاویه دید را به بیننده می‌دهند. معمولاً فاصله کانونی آنها بین ۶ تا ۱۶ میلیمتر است.
Deutsch: Das Fischauge bezeichnet in der Fotografie ein spezielles Objektiv, das mit der dazu nötigen Verzeichnung ein komplettes Gesichtsfeld abbilden kann. Im Gegensatz zu konventionellen Nicht-Fischaugen-Objektiven, die eine senkrecht zur optischen Achse stehende Objektebene proportional abbilden (gnomonische Projektionsweise, siehe unten: Abbildungsfunktionen), bilden Fischaugenobjektive eine Hemisphäre oder mehr, mit deutlichen aber nicht übermäßigen Verzerrungen, auf der Bildebene ab.
Русский: Ры́бий гла́з— разновидность сверхширокоугольных объективов с целенаправленно увеличенной дисторсией, другое название дисторси́рующий (или «дисторзирующий») объектив.
עברית: עדשת עין הדג הוא כינוי לעדשות צילום בעלות אורך מוקד קצר במיוחד, כלומר עדשות "רחבות" מאוד. אורך המוקד הקצר יוצר עיוות משמעותי של התמונה, ואף תמונה "כדורית".
Українська: Риб’яче око — об'єктив, особливістю якого є дуже широкий кут зору, який створює сильне викривлення. Призначений для створення широкого панорамного або напівсферичного зображення.
Français : Un objectif fisheye, raccourci en fisheye, ou objectif hypergone, est un objectif photographique ayant pour particularité une distance focale très courte et donc un angle de champ très grand, jusqu'à 180° dans la diagonale, voire dans toute l'image.
Svenska: Fiskögeobjektiv eller fisheye är ett vidvinkelobjektiv som används till kameror och som bidrar till en cirkulär bild. Extrema vidvinklar med en bildvinkel på cirka 220 grader och okorrigerad s.k. tunnformig distorsion tillåter en stark optisk distorsion där bilden blir en sfärisk form. I motsats så strävar ett vanligt vidvinkelobjektiv efter att räta ut bilden och förhindra distorsion.
