lens cleaning

[SmartWombat]

I use a microfibre cloth and Pentax lens spray (for glasses) in an emergency.
Normally I use Eclipse fluid and pec-pads.
But you can't fly with Eclipse fluid so when going abroad I use Pentax spray.

If I don't have anything else then I use tissue paper:

- Fold the paper into a tube so that it has a point but is still flexible
- Breathe on the lens so it gets condensation
- Hold the paper by the tube and gently rub the point on the lens covered in condensation in little circles
- Breathe on the lens as often as needed to keep the condensation

Note that all my lenses have UV filters. I only do this operation on the filter, not the lens itself
