Has anyone tried these "lens Pens" for cleaning their camera lens? They claim to have a "clear Carbon" material good for 500 cleanings. I have tried a similar product for eyeglasses and am quite satisfied with the results. Still not sure if I would use it on my camera lens.

Thanks for the information Dick. It was well explained.

Thanks for the comments. They were all helpful.

I am new to shooting Raw and new to the forum. Please excuse me if what I thought to be true about shooting Raw is incorrect. I thought that when you shoot Raw that you have the ability to change all camera settings in post processing. Using Lightroom CC I can only see where to change White Balance. Changing exposure does not allow me to change shutter speed or f stop or ISO specifically. What does changing exposure exactly do? Does it change each of the three, ISO, shutter speed and f stop in its own combined manner? Sorry for my confusion. Any assistance with this is appreciated.

My name is Tom. I am retired and enjoy photography. The photo I included was taken with my old Nikon D50 with an 18 - 55mm lens. I have recently upgraded to a Nikon 7200. I have been reading the forum for a while now and enjoy it very much. I have learned quite a bit and hope to continue to do so.
