My aunt gave me the old camera and lens. I think it had been sitting in her garage in California for a long time. I haven't used anything but digital point and shoots since high school, and I was frustrated not having the instant result of seeing the picture on the screen. I learned on a manual camera, and developed my own pictures. I seem to have forgotten how to use manual settings. My trial and error method was getting expensive, buying film, developing/ printing, etc. I've been wanting to get back into photography, and try a dslr. I picked out the d3100 after reading that it would work with this old lens, and was supposed to be a good entry level dslr. I just signed up for a photography class in March.
