Here's a thought ... just a different approach ... since I work with a number of different CCD cameras I discovered this technique seemed to be relatively effective in mitigating jaggies. Each new camera is different, presents new processing challenges and has to be worked out.
For this specific MM camera file of the Bridge, I base it off a 20" print at 360 ppi because that is the largest I can print on my Epson 3880. I would not be overly ambitious in enlargement sizes with a 18 meg file anyway. Anything will produce saw-tooth jaggies eventually ... the M9 does it much sooner than my S2, and S2 sooner than my H4D/60 ... the only cameras I've seen without an AA filter that defies luminance aliasing well past 100% are Sinar and Hasselblad Multi-Shot MFDs.
The notion is to preserve micro contrast by reducing any RAW software sharpening to zero, and even reduce the Clarity slider a bit ... then use the broad array of exposure tools in LR4 to produce more acute micro contrast ... effectively making the image look sharp without resorting to edge sharpening or wholesale contrast tools like Clarity.
I think it is also important to recognize that a file at "fit to" a computer screen is not the best evaluative tool for this specific exercise. My 30" monitor displays at 2560 X 1600 ... a 20" file @ 360 dpi is 7200 X 4791. So, when figuring out a new camera, I crop sections of any demo image @ 100% and print them, then adjust accordingly.
Rather than try to demo what I mean here at 1200 pixels wide ... I did quick version using the technique outlined above, and loaded it to my "Jono's MM Processing gallery" on SmugMug. ... There is a full image, a crop (which is sort of ridiculous, since it represents a print the size of a bill-board : -) ... and I also placed the LR settings that I used as a screen shot for easier reading ... (also shown below at 1200 pixels).
It is STILL a downsized version jpg on SmugMug, so DO NOT just view it at screen size ... place your cursor over the large preview image to the right and click on it, then select "Original" in the top right corner for a larger version to scroll around and pixel peep. This SmugMug version is no-where as good as the full 20" version on my screen, which in turn sucks next to the print I pulled ... and from direct experience the inkjet print I made will suck next to a laser print on a good silver based photo paper
