This is a quick look at the FM10, if you want to learn about photography, your best choice is a manual camera and this is a good one.
I have a Nikon F301 and still use it along with my digital camera, although my Nikon has many automatic features I use it mostly on manual override.
Although digital cameras have very useful advantages there are many times when a manual film camera has more versatility, you only have three controls to think about, aperture, shutter speed and focusing, my digital camera has about 90 different options, most of which I don't even understand let alone use.
