Nikon 18-70 DX AFS 3.5-4.5 G
Sigma 18-125mm F3.5-5.6 DC
To make the test I have used an ISO 12233 chart printed in a DIN A3 paper sheet by a Xerox M24 laser color printer to its maximum resolution. The shot has been made with automatic shutter , trying to do no movements with fingers and the metering was matrix and aperture priority. The camera was a Nikon D50 shooting NEF. The NEF files was opened up with Nikon Capture NX and then opened, as TIFF, to Photoshop CS2 and reduced for web, without retouch anymore. It has been compared the best thing and the worst in a lens: the center and the border to diverse focal and apertures.
