The same lenses for the KX121 will fit the CX161, scroll down on this page for available lenses:
William, that is a good idea about a lense cover. You'd obviously want to select something that was optically clear, and if it happens to be coated, all the better. I think any material designed for regular photographic lenses would be a good choice, it comes down to finding something small enough, or something that can be cut easily to fit.
