The test wasn't thorough enough IMHO. You should have compared the normal lens with in camera SR and the OS version of the lens without SR.
I read that somewhere the OS lenses have a plus optical element that isn't part of the image reproduction system of the lens, that makes only the reduction of the shaking. But this optically unnecessary element spoils a bit the optical efficiency of the lens.
I don't know is it true or not but it sounds logically.

I don't see too much difference between them. The sharpness seems to identical for me in both case. But it seems the set 'A' has a bit more contrast.

It depends on how much you would like to spend on it. As david said the landscape shots need wide angle lenses and the short tele (under 200mm, generally between 50-135mm) lenses are the best for the portrait shots. You need a 18-55mm, 16-45mm or 16-50mm lens for the landscapes and a 55-200mm for portrait. You can choose Sigma lenses too.
The buying of an ultra-zoom lens like Sigma 18-125mm, 18-200m or 18-250mm could be a good choice too.

Same result here. I too got the exec icon. Maybe some OS X update will solve it...

Maybe I've found the solution on this forum.
You should remove the com.apple.finder.plist and com.apple.finder.plist.lockfile from the /Macintosh HD/your username/Library/Preferences folder, log out and in and after that it will work.
Some supplements: I didn't notice any changes until I moved the PEF file to new location. Then the OS X generated a new preview for the PEF file.

I got similar result by googling as Matt. The problem was well known in Lion too and the thumbnails don't work with .PEF, .ARW (SONY) and .RW2 (Panasonic) files.
I didn't find any stable solution to this problem.

I made a trial shot in PEF format with my K20D and I have to say that this format isn't supported by the Finder. I can look it if I hit a space button but the icon is an empty white sheet.
It is very interesting...

Does your PP software (Aperture/iPhoto/Lightroom/etc.) can handle this format? If you have similar problem with your PP software then you should download the Digital Camera Raw package here.
I chose the DNG file format on my K20D and it works well with the Aperture v3.3.2 and the Mountain Lion's Finder.

This is nice at fix focal length lens but the zoom lens doesn't contains these marks because the hyperfocal distance depends on the focal length too.
There are many smart-phone applications to Android like 'DoF calc', 'Photo Tools', etc. They have another useful functions like checklists, level indicator, gray card, etc.

You should check out the OpticFilm series of the Plustek. If I know it well they have the highest resolution (7200x7200 dpi) and the highest colour depth (48 bit/pixel) on the market.
