Front
control, the left button activates the self-timer, the center button brings up the menus, the right button sets the flash mode and the bottom button switches the camera into playback mode. Below the 4-way controller, there is a display button on the left that cycles the information displayed on the LCD in shooting mode, and puts the display into “High Angle” mode. The burst/trash button is at lower right. 
Right Side
The strap lug is flush on the top of the right side, so it won't get in the user's way. It's the right size for a wrist strap. The metal decoration on the handgrip wraps about halfway across the right side of the cameras. The door for the SD media slot is also on the right side, and closes flush with the surface, not affecting the comfort of the grip.

Top
The shutter release is a small chrome button toward the right of the top. It's surrounded by a ring that activates the zoom in shooting mode and magnification in playback. The power switch is a small slider switch that's easy to use, but unlikely to be accidentally turned on. We prefer power switches like this one, because accidentally turning on a camera is pretty common, and if a camera turns on while it's in a purse or pocket, it can be damaged. At the very least, its batteries will run down.

The optical image stabilization button is small and to the right of the shutter release. It's marked with a picture of a quivering hand. The left side of the top is flat, but embellished with a bit of branding: it says “Panasonic DMC-LZ5” (or “Panasonic DMC-LZ3” depending).
A small hole toward the middle of the top admits sound to the microphone, and the mode dial slightly overhangs the back.
Bottom
The battery compartment of the LZ5 and LZ3 is inside the handgrip, and accessible through a door on the right side of the camera's bottom. The door is sturdy, and requires a firm press and slide to open, but it does not have a latch. We have found that latched doors are more secure and long-lasting. The cameras appear to have tripod sockets, but the cameras we inspected had security devices blocking them.
