Standard AW: Canon Powershot SX50 HS - Praxisthread

Hallo,

anbei einige Fotos.

Die SX50 wählt "ohne Not" idR 640 bis 800 ISO im HiSpeed-BurstMode HQ, auch wenn sehr gute Lichtbedingungen herrschen, die bspw. Aufnahmen mit 1/500 bei 100 ISO zuließen.

Im unteren Brennweitenbereich wählt die SX50 im HiSpeed-BurstMode HQ immer noch "nur" 250 ISO bei idR 1/1000 Belichtungszeit, um auf die ca. 13 Aufnahmen pro Sekunde zu kommen, die Canon für die SX50 propagiert.

Die Tests mit CHDK und Benutzer-Auto-ISO zeigen, dass die Aufnahmen auch bei wesentlich günstigeren ISO-Werten möglich wären.


Viele Grüße
canontestit
