Viewfinder (4.5)
The viewfinder is a comically small real image optical zoom viewfinder, and the most amusing aspect of it is that it’s even there. The image seen through it will not be the same as the final image, and even the manufacturer suggests using the LCD if close-up shots are being taken. I suggest using the LCD screen all the time, unless you really want the eyestrain.

LCD Screen (5.5)
The LCD for the Canon PowerShot S410 is placed on the back, and sits slightly above the rest of the camera body. It is 1.5 inches diagonally, with 118,000 pixels, and is a low-temperature polycrystalline silicon TFT color LCD.

Flash (6.5)
The Flash for the Canon PowerShot S410 is an in-camera flash, which rests flush with the rest of the camera body in the upper left corner on the front. Flash settings are controlled via the right arrow button on the four-way controller. The settings available to the user are Auto, Auto with Red-Eye, Flash On, Flash Off, and Slow Synchro.

Zoom Lens (6.5)
The Canon PowerShot S410 has an f/2.8-4.9 7.4-22.2mm lens (36-108mm 35mm film equivalent). The zoom on the Canon PowerShot S410 is a 3x optical/3.6x digital, for a total zoom of approximately 11x. This is a pretty standard zoom for a camera of this stature and will sufficiently fill the needs of the average point-and-shooter.
