DescriptionThree Minolta 50 mm photographic lenses with different lens speeds of 3.5, 1.7, and 1.2.jpg |
English: Three Minolta 50 mm photographic prime lenses with different lens speeds of 3.5, 1.7, and 1.2. The lens with lens speed 3.5 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. The lens with lens speed 1.7 in the middle is a standard lens coming with many SLR cameras, here from the Minolta AF assortment of lenses from the 1980s. The lens with 1.2 on the right 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. The image is meant to show the relation between entry lens diameter and lens speed. Deutsch: Drei Minolta-Objektive für SLR-Kameras mit je 50 mm Brennweite und Lichtstärken von 3.5, 1.7, und 1.2. Das Objektiv mit Lichtstärke 3.5 ist für die Makrofotografie gedacht, wo 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 ist (vom Typ) ein Standardobjektiv vieler Spiegelreflexkameras, hier aus dem Minolta AF-Sortiment an Objektiven aus den 1980er Jahren. Das Objektiv mit 1.2 auf der rechten 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. Das Bild soll das Verhältnis zwischen Eintrittslinsendurchmesser und Lichtstärke illustrieren. |
