TS is pretty misleading to say he/she shot these at wider apertures when the exif data shows f/22.. seems like he/she dunno the basics well enuf yet :sweat:
TS, try blowing the sensor first. there's this function in ur menu "Clean sensor manually" whereby the mirror will lock up and the shutter curtain opens, revealing the sensor. mount it on the tripod first, make it point downwards and blow the sensor with a blower. if the spots still appear at f/22 then bring it down to NSC n get it cleaned.
And so many of us concluded that it was dust even with a wrong description. Haha.. Amusing rite?
