I recently acquired a used A7r which is in need of a sensor wet clean. There's a few large spots that the camera shake and indeed a blower can't remove. I'm aware that the shake mechanism of the camera needs locking down and how to do it. I'm also fairly comfortable with wet cleaning sensors as I've been doing this for some years on both Canon and Leica cameras ( without doing any damage). What I can't seem to establish is the swabs and fluid that are considered safe. I've always used isopropyl 70% with Invisible Dust orange swabs and wonder if anyone can advise from experience wh
I've recently started doing timelapse clips using my Canon 60D and interval shots. Because this often involves pointing the camera at large areas of sky and using small apertures to obtain slow shutter speeds, dust bunnies have suddenly become very noticable - maybe ten or a dozen faint but obvious spots on each image. I searched the internet on how to assess the extent of the problem and discovered how to shoot an out-of-focus area of sky and then use auto-levels on the image to show up the spots. SHOCK! It looked like a passing car had run through a puddle of dirty water and showered my sen
Watch out for this gotcha! It caught me out - so a warning, just something to bear in mind. I was using a Fuji X-E1 and 18-55mm lens but it will probably be a risk with any mirrorless camera especially with wide-angle lenses that have a rear element that comes close to the sensor. I took some photographs on a misty morning and when I processed them I discovered large shadowy smudges down one side easily visible with the large areas of flat light grey. I thought it was dust (but looked a bit odd) or a mark on the sensor but I could not see it with magnification and cleaning achieved nothing
