I did a quick Google image search. arimage's lens does resemble a Sears lens. If it's not in the database then this would be a good addition.

You are in the right place. There are countless knowledgeable individuals in this forum that I'm sure are more than willing to assist with whatever questions you may have with Pentax and photography in general. Enjoy the K7!
