Kodak Z650 Review
Kodak Z650 Optics
A 10x optical zoom range, with good performance.
5x Digital Zoom
The EasyShare Z650 zooms over the equivalent of a 38-380mm range, a little spare on the wide-angle end, but plenty long at full telephoto. The 5x digital zoom takes it out to 50x total, albeit with the loss of quality that digital zoom creates.
A small macro area with good detail and high resolution. Flash can't see over the long zoom, though, so plan on using external flash for macro shots.
|Standard Macro||Macro with Flash|
The EasyShare Z650's macro setting performs well, capturing a small minimum area of 1.76 x 1.32 inches (45 x 34 millimeters). Detail is strong and resolution high, with only a moderate amount of softening in the corners from the lens. (Most cameras have some softening in the corners in macro mode.) The flash casts a shadow of the zoom lens at close focus, however: Plan on using external lighting for your closest macro shots with the Z650.
Lower than average barrel distortion at wide angle, no distortion at all at telephoto.
Distortion is the tendency for the lens to bend straight lines outward (like a barrel--usually at wide angle) or inward (like a pincushion--usually at telephoto). The Z650's 0.57% barrel distortion at wide angle is lower than average. At the telephoto end, the Z650 shows no measurable distortion at all. All in all, much lower distortion than we're accustomed to seeing in digital camera lenses, particularly long-zoom models.
|Barrel distortion at 38mm is 0.57%|
|Distortion at 380mm is 0.00%|
Moderate to high chromatic aberration.
|Wide: top left @ 200%||Wide: top right @ 200%|
|Tele: top left @200%||Tele: top right @200%|
The Kodak Z650's chromatic aberration is moderate at wide angle and high at telephoto focal lengths, showing about 6-8 bright pixels of coloration. (This distortion is visible as a colored fringe around the objects at the edges of the field of view on the resolution target.)
Better than average corner sharpness. Lower right corner was soft at telephoto, but rapidly improved away from the extreme edges.
|Wide: slightly soft
in the lower right corner.
|Wide: very sharp at center.|
|Tele: rather soft
in the lower right corner.
|Tele: sharp at center.
Corner sharpness with the Kodak Z650 was generally pretty good. At telephoto focal lengths, the lower right corner of our test sample became rather soft, but the softness didn't extend too far into the image. Other corners looked better, and all corners were quite sharp at wide angle.
The images above were taken from our standardized test shots. For a collection of more pictorial photos, see our Kodak EasyShare Z650 Photo Gallery .
