after I shot picture outdoor. I always got dirt on the lenses. I use "Zeiss Pre-Moistened Lens Cloths Wipes", but one of my friends saying that is not good method to clean up. what would you guys prefer?
The main principle is to get the dirt off the lens before cleaning with a moist wipe of any kind!
1. Lenses and lens coatings are tougher than filters and filter coatings.
2. Lenses and lens coatings are tougher than most people think.
3. Learn proper lens cleaning technique and get proper supplies: Rocket blower, microfiber cloth, lens cleaning fluid (not Windex).
3-1: Blow dust off the lens.
3-2: Gently wipe the lens, holding it surface down, with the cloth held loosely.
3-3: Inspect and if suitable move to the next step. Do not go to the next step if there is any kind of grit on the lens.
3-4: Put a few drops of fluid on the cloth (never to the lens) and gently wipe the lens from the center in a slow spiral outwards, finishing in a smooth motion with drier parts of the cloth to be sure to remove all wetness from the lens.
If you don't have a blower, use your breath. Never use canned air.
If you don't have a microfiber cloth, use a soft cloth like a clean t-shirt.
If you don't have cleaning fluid, condense your breath on the lens by breathing with a a wide open dry mouth close to the lens.
Also important: Don't clean lenses too often! Just blowing dust off is usually all that is needed, and some dust won't make much difference at all except in extreme lighting conditions (ex. point sources or reflections in the frame or direct sun getting inside the lens hood).
