Digital Camera Review

At the Consumer Electronics Show earlier this month, Kodak unveiled their new Z line of digital cameras with the introduction of the EasyShare Z740 and Z700. The new Z-series supplements the DX line in Kodak’s “ultra zoom” camera segment, falling between Kodak’s current CX and DX lines. The EasyShare Z740 offers a 10x optical, all-glass lens with a 38-380mm (equivalent) zoom that refracts images to its 5 megapixel CCD. With a host of preset and manual control options, an intuitive interface, and an accessory lens available, the Z740 is set to appeal to the neglected alternative point-and-shooter. Those seeking advanced telephoto range and manual control, without sacrificing ease of use and effortless direct printing will appreciate the Z740, which should provide users room to expand and develop as they go.

Manual Control Options
While the EasyShare Z-line does not target manual users, a substantial amount of control is available for the photographically inclined. Exposures can be manually altered in full Manual mode as well as both Aperture and Shutter-Priority settings. The user can manually adjust the ISO rating, white balance settings (although no custom option is available), as well as color parameters. This is an expansive array of options for an otherwise point-and-shoot camera.

 

Focus
Auto
The Z740 has two primary modes of automatic focusing: multi-zone and center-zone. The user may also choose to leave the focus on continuously in continuous AF, or use the single-AF method and conserve some of the battery power. In Normal Wide, the Z740 will focus as close as two feet from the front of the lens, while in Normal Telephoto view, the camera can focus on images as close as 6.6 feet away. There are also Close-up Wide and Close-up Telephoto modes that reduce the space needed to focus to 4.7 inches (Wide) and 3.9 feet (Tele). The Z740 also includes an auto-assist illuminator to help focusing in low light.

Manual
There is no manual focus on the EasyShare Z740. Although the camera contains some manual modes and controls, it is directed toward automatic users.

 

Metering
The Kodak Z740 features automatic Through-The-Lens AE metering as well as three selectable metering settings when manual adjustments are warranted. These include multi-pattern, center-weighted, and center spot metering modes.

 

Exposure
The EasyShare Z740 offers exposure compensation in the typical +/-2 range; however, it moves in 1/2-stop increments rather than the standard 1/3-stop steps.

 

White Balance
The Kodak EasyShare Z740 includes an automatic white balance mode and four preset options. Among these are Daylight, Open Shade, Tungsten, and Fluorescent settings. This is a limited set of white balance options and, combined with the lack of a manual or custom setting, will likely force users into reliance on the automatic setting.

ISO
The Kodak Z740 offers both manual and automatic ISO selection. In manual mode, the available sensitivity range runs from ISO 80-800, while the available range in automatic mode is far more restrictive, only offering an 80-160 ISO range. While the Z740’s manual mode offers an expansive ISO range, the majority of the camera’s users will opt for the automatic setting. The 80-160 automatic range is significantly more restrictive than most point-and-shoot cameras, which typically offer an 80 or 100-400 ISO range. This puts the Z740’s automatic users at an extreme disadvantage, as the camera will only be able to render visible images under profuse lighting.

Shutter Speed
Shutter speed controls on the Z740 are manually alterable in both full Manual and Shutter Priority modes, ranging from eight seconds to 1/1000 of a second. In automatic mode, the camera will determine and set the appropriate shutter speed for the shot within a 1/8 - 1/1700 of a second shutter range.

Aperture
Like shutter speed, aperture settings are manually controllable on the Z740 in full Manual and Aperture Priority settings. The available aperture range runs from f/2.8-f/8 (Wide) and f/3.7-f/8 (Tele). The f/3.7 opening offered in full telephoto is extremely large, considering the extended focal length. This is beneficial to the telephoto enthusiast, who can open the aperture and record telephoto images with faster shutter speeds, reducing the chance of visible motion and blur in the image. This is invaluable considering the camera does not include an image stabilization function.
