Nikon D3100 help [tooshort]?
I just bought my first camera (upgrading from a point and shoot). I bought a Nikon D3100, and I have some questions. 1. I bought a 55-300mm lens and when I use that lens, is a bit blurry. I can change my 18-55mm, and works well. Why is my 55-300mm blurred? 2. Every time I walked into the playback mode, which displays the image in a small corner in the top left and right, shows the levels of some things. How I can see the whole picture? 3. When I bought the 3100, said he came to the GEO coding, the GPS. "I can get more information about it, and how to use? If I have more questions I can think of, I'll be sure to edit this entry. Thanks. : D I did read the manual. It confused me.
I bet the manual feels abandoned. Read the manual.
