Summary

English: The above image shows the relation between entry lens diameter and lens speed. Three Minolta 50 mm photographic prime lenses with different lens speeds of (from left to right) 1.2, 1.7 and 3.5. The lens with lens speed 3.5 (most right) is for macro photography, where the lens speed is of less concern in comparison to the achievable depth of field, thus it has a small entry opening resulting in the lens speed of 3.5. A lens with lens speed 1.7 like the one in the middle was delivered with many SLR cameras as a standard lens in the 20th century, here from the Minolta AF assortment of lenses from the 1980s. The lens with 1.2 on the left is from the non-AF Minolta lens series from the 1970s and early 1980s. The speed of 1.2 results in a very large entry lens (large opening) enabling, e.g., photography at low light, and resulting in a relatively high sales price (link to a review of the lens from 2013). Deutsch: Das obige Bild illustriert den Zusammenhang zwischen Eintrittslinsendurchmesser und Lichtstärke. Drei Minolta-Objektive für SLR-Kameras mit je 50 mm Brennweite und Lichtstärken von (von links nach rechts) 1.2, 1.7 und 3.5. Das Objektiv mit Lichtstärke 3.5 (ganz rechts) ist für Makrofotografie, bei der die Lichtstärke im Vergleich zur erreichbaren Schärfentiefe weniger wichtig ist, daher hat es eine kleine Eintrittsöffnung, was zu der relativ geringen Lichtstärke von 3.5 führt. Das Objektiv mit Lichtstärke 1.7 in der Mitte war (vom Grundtypus) das mitgelieferte Standardobjektiv vieler Spiegelreflexkameras im 20. Jahrhundert, hier aus dem Minolta AF-Sortiment an Objektiven aus den 1980er Jahren. Das Objektiv mit 1.2 auf der linken Seite stammt aus der Minolta-Objektivserie ohne AF aus den 1970er und frühen 1980er Jahren. Die Lichtstärke von 1.2 wird durch eine große Eintrittsöffnung erzielt, was z. B. das Fotografieren bei wenig Licht ermöglicht, und führt auch zu einem relativ hohen Verkaufspreis (Link zu einem Testbericht des Objektivs von 2013). |
