Viewfinder
The electronic viewfinder is surrounded by a soft plastic eyepiece, which adds some comfort while shooting. A small button labeled “EVF/LCD” is located on the left side of this feature; this is used to switch the display from the LCD screen to the viewfinder. Also on the left side of the viewfinder is a small diopter adjustment; users will have to jam their fingernails in the side of the viewfinder to use this, but the option is rare on compact digital cameras. The viewfinder uses less battery power and has better resolution with 311,000 pixels. The shade of the eyepiece may be handy for shooting in bright light outdoors.

LCD Screen
On the back of the Kodak EasyShare Z7590, a 2.2-inch LCD screen displays histograms and captured images, as well as doubling as a viewfinder. The screen boasts 153,000 pixels.

Flash
The Z7590 has a built-in flash with four modes: Auto, Red-Eye Reduction, Fill, and Off. This flash reaches from 2-16.1 feet and also has a flash exposure compensation mode that can be adjusted from +/- 1 in ½ steps. This camera also has a flash sync connection, the first Z-series camera to do so.

Zoom Lens
The Kodak EasyShare Z7590 has a 10x optical zoom Schneider-Kreuznach Variogon lens that measures from 6.32-63.2mm. In 35mm format, this is equivalent to a 38-380mm lens. At the rim of the lens is a step-up ring, so optional conversion lenses can be fit onto it. The lens has an aperture range from f/2.-f/8. As with other SLR-shaped Kodak cameras, the Z7590 has a lens cap that tethers to the neck strap or side of the camera. If 10x optical zoom is not enough, Kodak threw in an additional 3x digital zoom.
