Nikon Coolpix S7c Optics
Pretty good results with the 3x optical zoom, though with some blurring in the sides and corners of the frame.
|35mm||105mm||4x Digital Zoom|
The Nikon Coolpix S7c's 3x optical zoom covers the equivalent of a 35-105mm range, which is about average among other digital cameras in its class. Overall results were pretty good at wide angle, though with some noticeable blurring in the corners and sides of the frame and a very small amount of coma distortion. The camera's 4x digital zoom held onto a fair amount of fine detail, though overall results were blurred with higher noise and lower resolution, as you might expect from digital enlargement.
A tiny macro area with excellent detail and resolution. Flash is a little uneven, but still useable.
|Standard Macro||Macro with Flash|
Nikon digital cameras have always performed well in macro mode, and the Coolpix S7c upholds the brand's stellar reputation. The Coolpix S7c captured a very small minimum area of 1.12 x 0.84 inches (29 x 21 millimeters). Detail and resolution were both excellent, and there's barely any softening in the corners of the frame here. (Most cameras have some softening in the corners in macro mode, so the S7c actually performs very well.) Though the flash exposure is a little uneven, results are still useable, depending on the application.
High barrel and pincushion distortion.
|Barrel distortion at 35mm is 1.16%|
|Pincushion at 105mm is less than 0.75%|
This 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 Coolpix S7c's 1.16% barrel distortion at wide angle is much higher than average among the cameras we've tested. At the telephoto end, the S7c's 0.75% pincushion distortion is also much higher than average.
Moderate, minimal effect on images at edges.
|Wide: moderate but dull,

Chromatic aberration is moderate at the wide angle lens position, showing about 10+ pixels of dull coloration on either side of the target lines. However, the effect is exacerbated by some blurring in the corners of the frame. At telephoto, the distortion is much lower, with very dull pixels. (This distortion is visible as a very slight colored fringe around the objects at the edges of the field of view on the resolution target.)
Strong blurring in the corners of the frame at wide angle, and a moderate amount at telephoto as well.
|Wide: Quite soft in the
corners (upper left)
|Wide: sharp at center|
|Tele: soft in the
corners (lower right)
|Tele: sharper but still slightly soft at center|
The Nikon Coolpix S7c produced very soft corners in a few shots, particularly at full wide angle. At telephoto, moderate blurring was also visible in the corners, with the strongest effect in the lower right corner.
