Re: New Puts article
I think Irwin's comparison between the boosted E420 and boosted M8 image is a bit deceptive - if you take a close look at the M8 MTF plot, there are components above the Nyquist frequency at the 0.6-0.8 level, partially obscured by the legend. Those would be easily visible as artifacts in a final image, whereas in the E420 image those components are far lower, and would be far less visible. A better comparison would be how far both images could be boosted with the same levels of artifacts in the above-Nyquist range. I think that would show the boosted E420 and boosted M8 image as significantly closer together. Although the M8 image is always going to be better; no way any processing brings up a kit zoom lens to prime lens quality levels.
