I really should make a shot of the pear with a bite out of it, to signify the end of the test.

Method
I opened the first image in Photoshop CS3, increased the exposure a little; sharpened to the 100 indicator with the sharpen slider in the Sharpen tool and then applied the same parameters to each of the other shots.

I shot one shot with the 18-55mm lens at fixed ISO200 and then a shot at ISOauto. I did the same with the 12-24mm lens.

The ISOauto setting accounts for why one shot is at ISO720 and one shot at ISO640. I don’t think the difference is significant.

All shots were taken with the focal length set to 24mm.

After I had opened the four shots, I set the rectangle tool to a fixed size of 475×475 pixels in each case. I then copied that section of the photograph into a ‘new’ image and saved-for-web.

Judge the sharpness of each for yourself.

Photoshop is an image editing program but it does not rely on an imported image. The tools within the program can produce an image also.
