good one minute, bad the next.
was test shooting a series of compositions at tele, then half way through my shots, the sensor attracts contamination. I guess the matter of keeping ones sensor clean is not restricted to just the sensor but the entire innards of the sensor area. good grief.
when I got home, I blew some air on the sensor area. tests showed it got rid of the top right debris.
but if you look carefully, especially in 1:1 view there is contamination on the sensor that required me to use a wet solution. will test tommorrow to see if it was effective.
