Summary[edit]

Description
Deutsch: Das smc PENTAX-F 28 F2.8 ist ein Weitwinkelobjektiv mit fester Brennweite, hergestellt von der japanischen Firma Asahi. Genauer gesagt, der Firma 'Asahi Optical Co., Ltd.'. Produziert wurde es von 1987 bis 1989 und war für 35mm Film Spiegelreflexkameras ausgelegt. Dieses Format nannte sich damals noch Kleinbildformat und entspricht dem heutigen Vollformat. Das F2.8 steht für eine maximale Blendenöffnung von 2,8. Seine minimale Fokusdistanz beträgt 30 cm und es hat ein Gewicht von 180 g. Der Äußere Teil des Gehäuses entpricht dem der beiden 50mm Objektive mit F 1.4 und F1.7 aus dieser Serie. Auch dieses Objektiv wurde in der Nachfolgeserie mit etwas abgeändertem Gehäuse weitergeführt.
