Every camera manual recommends a maintenance schedule that assumes you have unlimited time and a climate-controlled workspace waiting between every job. Real working conditions rarely allow that, so here's the honest, reduced version of camera maintenance that's actually kept my bodies functional through years of dusty, humid, chaotic event work.
Sensor cleaning: less often than you think, but not never
I don't clean sensors on a fixed schedule. I check for dust spots by shooting a blank wall at a small aperture every few weeks and only clean when spots actually show up in the corners at a level that would matter in delivered work. Cleaning more often than necessary introduces more risk of scratching a sensor or introducing new dust than it prevents, so the "clean constantly to be safe" instinct is actually backwards.
The habit that's saved me more than sensor cleaning ever has
Checking and reseating memory card contacts and lens mount contacts with a dry cloth after any shoot in dusty or sandy conditions has prevented more actual failures than any sensor-cleaning routine. Dust and grit in a contact point causes intermittent connection issues that are maddening to diagnose mid-shoot and completely preventable with thirty seconds of attention beforehand.
- Clean sensors only when dust actually shows up in test shots
- Wipe down contacts after dusty or sandy conditions, every time
- Let batteries fully cycle occasionally rather than always partial-charging
What I've genuinely given up on
The recommended full weatherproofing check before every single outdoor shoot, testing every seal and gasket, doesn't happen in my actual workflow, and I've made peace with that. I do a real weatherproofing check maybe twice a year and rely on being reasonably careful the rest of the time. Perfect maintenance discipline that never actually happens is worse than an honest, reduced routine you'll genuinely stick to.
