DSLR sensors sit behind mirror mechanisms, requiring different cleaning angles and longer nozzle reach but offering more protection during normal operation. Mirrorless sensors typically need more frequent cleaning but respond better to gentle blower maintenance.
How do I know if my sensor cleaning was effective?
Take test shots at f/11-f/16 against a plain white or blue background, then examine images at 100% magnification for dark spots that appear in consistent locations across multiple frames. These spots indicate remaining sensor contamination requiring additional cleaning. Professional technique should achieve 95% particle removal in single cleaning sessions, with clean test images confirming successful maintenance.
Can sensor blowers generate static electricity that attracts more dust?
Standard rubber and plastic blowers can generate significant static charges (1,000-2,400 volts measured in testing) that actually increase dust attraction to sensor surfaces. Anti-static blowers use specialized materials and coatings that maintain electrical neutrality during use, eliminating this problem while improving overall cleaning effectiveness. For photographers in dry climates, anti-static properties prove essential for consistent results.
What type of dust particles are most difficult to remove with blowers?
Fibrous materials (clothing lint, paper particles) and electrostatically charged particles prove most challenging for blower cleaning. Fine silica dust and pollen typically remove easily with proper technique, while oil-based contamination requires professional wet cleaning methods. Filtered blowers handle challenging particles more effectively through consistent air pressure and contamination prevention.
