I am interested in writing a few question and answers to provide some general knowledge for questions that either appear often or would make good reference questions to link people to.
The two I specifically have in mind are "How do I identify the difference between Nikon DSLR full and cropped frame cameras and lenses?" and "How does crop factor apply to Nikon DSLR full and cropped frame camera and lens combinations?"
On this site, are "Question and Answer" (where the user posts both a question and answer simultaneously) questions like these appropriate/helpful to post, or are they obnoxious and unhelpful?
