The Nikon FM2 in Chrome and Black
a lot of people prefer the chrome and black
but for some reason professionals prefer the solid black
they are identical other than color in operaton and durability.

Note on the left side of the lens mount area is a blade type switch with white on it, this is the timer, if you put this on a tri pod or other surface and have it focused and set the apature and shutter speed, you can pull down on the timer and get yourself into the photo it gives you time to do so. One other use is to use it and not hand hold it and it will not have photographer shake when you take the photograph.

the lever next to it on the left by the lens mount is the lens release, to change lenses or to take a lens off to clean it or the mirror, you need to move this switch to disengage the lens from the camera.

on the right side of the lens mount is a round button down low. This is the depth of field preview button. Before you take a photograph with this camera you can get your settings the way you want them for the shutter and F stop and while looking through the lens it will show you how your exposer is going to look. Very useful if your doing exacting work, like evidence photography, or anything where clarity and exposer are critical.

up higher on the right side you see a round plug, this is where your flash sync attaches to tell the flash when the camera is taking a flash photo to keep it in time with the camera.
if you use a flash on top of the camera on the flash mount, it will connect to the flash with the hotshoe, but if you use a seperate flash not mounted or you wish to put an angle to the flast, then you need to hook the sync cord to the camera via this plug in.
