Clean the lens everytime after using?

Open it and get comfortable using it.

I put expensive, clear (not UV) filters on almost all my expensive lenses (including the fixed prime on my RX1R. I use B&W F-Pro, but there are others equal in quality and value. I often work near (or in) salt water.

Bonus: I tripped at the top of a strenuous hike, and banged my camera on a rock edge. Broke the filter. No damage to the lens.

The one exception for filtering is my sharpest lens. I don't keep a filter on it. I put one on when there is any danger to the lens, however.

Blow, then brush, then wipe. Never use your mouth or your breath (neither is clean). Never brush without blowing. Never wipe without brushing. The Lens-pens come with brushes.

All that said — the images you record are more likely than not to be unaffected by a not-too-dirty-but-not-pristine-either lens. Next time you think your lens is dirty, record some exposures, the clean the lens and record similar exposures. Load them into your viewer and compare them.

Guys, do you think it is a good idea to check for dust and dirt on the lens using a bright led light? Because under normal lighting it looks clean. But alot of things can be seen using a led light.

Frankly, I think you are way over reacting to this subject. Get out and take pictures and stop worrying about if the lens is antiseptically clean!

I guess so too. Wasted too much time cleaning the lens.

This is easy to test yourself.

It is not worth examining the lens with the bright LED light. Because what you would see would be how light scatters in an oblique direction off the lens. There is very little correlation between that and how light is being transmitted through the lens. It has to do with the structure of the scattering structures at the level of the wavelength of light.

Most really good optical surfaces look really bad if you examine them with a bright enough light. So don't torture yourself about it.

I guess so. I got a watch that looks very clean on the dial under normal lighting. Once I shone a bright led light on it. There will be some micro specks of dust appearing on the dial.

Does shinning bring led on the lens burn off the image sensor? I will stop doing that.
