USEFUL AND HELPFUL INFORMATION ON CARING FOR YOUR CAMERA GEAR FROM A MAJOR MANUFACTURER
The only thing that I have a disagreement with, and it is a simply a personal issue is the use of a micro fiber cloth to clean lenses. While they do work, most people do not clean them which eventually can add dirt to your lenses and contacts.
The dirt goes somewhere and oils and particles are absorbed into the cloth. It will transfer to your optics and camera overall.
If you are going to use them make sure they are washed in a plain dishwashing soap. No hand softeners. If you throw them in with the was make sure there are no softeners in the wash as well. Softeners contain wax and you sure do not want that.
Otherwise this is a great video to put all of us on the right track.
