<p>My 15-year-old daughter signed up for a summer course in photography. As she was preparing for it, she asked me at dinner time, a bit confused...<br> "Dad?" <br> "Yes?"<br> (reading from class description) "For my course I need a, um, manual, 35, er millimeter, um film single lens, what the hell is that, reflex? Do you have such a thing?"<br> "Why yes, yes I do."<br> So my lovely Nikon FM2n came off the shelf, a nice Nikkor 50 mm f/1.8 went on the front, and presto...another goes over to the good side of the Force!</p>
