Beschreibung
G.Zuiko Auto-W 1:2.8 f = 25 mm
Ein solide gebautes Weitwinkelobjektiv des PEN F-Systems, welches sich durch hervorragende Schärfe und herausragende Auflösung auszeichnet.
Im Lieferumfang waren Köcher, Vor- und Rückdeckel enthalten.
Kann ohne Probleme an neuzeitliche Evil-Kameras - wie z.B. in den Bildbeispielen an eine Sony NEX 5N - adaptiert werden. Hierbei werden - auch an dem "großen" APS-C-Sensor - hervorragende Ergebnisse erreicht.
