Kodak separates its digital cameras into five lines, each of which has its own look and feel and crosses a wide range, from the most basic point-and-shoot to superzooms with full manual exposure controls. The new 7.1-megapixel EasyShare Z710 is part of the company's High Zoom line and includes a 38mm-to380mm (35mm equivalent), f/2.8-to-f/3.7 10X optical zoom lens; full manual exposure controls; and 17 scene modes. Strangely, the Z710 lacks optical image stabilization, which is almost inexcusable in a camera with 10X optical zoom.
The camera's design is like a cross between the EasyShare Z612 and Z650, with a shiny silver plastic plate atop a rubberized grip. The plate houses the shutter button, along with controls for flash, macro or landscape mode, and drive mode. Since all controls are on the right side of the camera, with the exception of the slider that makes the flash pop up, one-handed shooting is possible. But if you relish the stability offered by two-handed shooting, something we always recommend, the rubber ring around the lens barrel will help you keep your grip. The 2-inch LCD is small for a camera of this class, though it didn't wash out too much when shooting outdoors in our tests. The EVF boasts 201,000 pixels but its images look somewhat coarse compared to others we've seen. The most annoying thing about the Z710's design is that the flash pops up every time you turn the camera on. You'll have to break out the duct tape if you get sick of pushing it back down.
Like other recent Kodak cameras, the Z710's controls are rather intuitive. A large dial on the camera back lets you choose your shooting mode, though all manual exposure modes, as well as program, are grouped under one setting. This may seem strange, but it lets you switch between manual, and aperture- or shutter-priority quickly using the tiny joystick, which also lets you change shutter speed, aperture, ISO, and exposure compensation. All these values are displayed on the LCD, so all you have to do is navigate from one to the next and change them as needed. It's a comfortable and efficient design. Unfortunately, the joystick has a smooth plastic coating over it. A rubber or textured finish would've made it much easier to use. Our thumbs frequently slid off the bottom of it when adjusting settings.
All the efficient controls don't help the fact that the EasyShare Z710 performed very slowly in our performance tests. The camera took a snail-like 5.5 seconds to power up and capture its first image. Capturing subsequent images, the Z710 took 2.8 seconds between shots with the flash turned off, and 2.9 seconds with flash enabled. Our shutter lag results were somewhat strange. In our high-contrast test, intended to mimic bright lighting conditions, shutter lag measured 1.6 seconds. Thanks to the camera's bright focus-assist lamp, which didn't activate in our high-contrast test, the Z710 only took 0.7 second in our low-contrast test, which mimics low-light shooting. Continuous shooting is limited to three shot bursts, but the camera was able to capture an impressive average of 2.5 frames per second regardless of image size.
