Hello!
I own a CVF Back and noticed a lot of small spots after long exposure shooting in cold nights in Montreal (-20c)...
this is certainly no matter with cold but the long exposures on skies is showing obvious dark spots.
I removed my lenses and the spots seems hard to read (extremely blurry) when I take a picture without lens,
how come the dust located on the sensor itself would be showing sharper with Lens ? normally, the dust should look exactly the same without lens if its located on the filter ? am I wrong ?
My other concern is that Dust is located exactly at the same spots even with different Lenses, 80mmor 150mm, and obviously sharper and crispier at f22...
do you think the Dust is behing the IR filter? I cleaned the surface gently but its still there...
thanks a lot for your advice.
