In the past, Roger has shown us time and time again, that internal dust and other artifacts rarely have an effect on the image quality produced by your lenses. With how complicated the optics in a lens are designed, lenses are rarely affected by these small flaws such as lens dust. That said, every piece of equipment that is on the shelves at LensRentals.com is thoroughly cleaned and inspected multiple times before being shipped out. Cleaning and regular inspection of your gear and help prolong the life and help give you the highest quality of images possible. Today, I’d like to take you through how we often clean and inspect the glass that gets shipped back and forth from our office, and some of the problems that we face.
