We're still using the English system of measurement, generally, yards, feet, inches, pounds, quarts, all that stuff. I think the shilling is still good here, too, but I'm not sure. We also have the American Standard Unit of Vertical Measurement, as well: the Washington Monument.
For our friends in those areas that use the more "scientific" systems of measurement, the reason I'm poking fun at those phrases is because the news-faces on TV always seem to put distances in those terms, probably because the average WalMart shopper can relate and he never did understand fractions or powers of two.
Here's another of my "test" shots, subject: a 1989 GMC Suburban that's seen better days. (Testing the rotating collar on the lens.) I was thinking of cropping out the chrome mirror, enlarging it, and using it in the "cloudscapes" thread - there's reflections of some clouds there, marvelously distorted. Btw, the lens came with a circular polarizer that fits inside the lens in a special holder towards the back end. Has a little thumbwheel on top that you can use to adjust the CP filter with a gearing system in the holder - so the whole filter rotates, rather than one of two rings in the filter itself. I had that CP filter installed in the lens when I took those pictures, but forgot to rotate it to get the best pictures.
One important thing I learned from the incident related in another thread (
My K1 shell is cracked. Will Precision Camera replace that? - PentaxForums.com) : don't try to support the weight of the lens with the camera - don't attach the camera prior to installation of the lens on the tripod, and remove the camera from the lens before removing the lens from the tripod. And use the strap attachments, just in case. Although the lens in the case reported was defective, it gave me a chance to observe and think about how fragile the mounting "hardware" is. And that lens weighed about half of what this one does. Ricoh ought to add that little tip to the instructions pamphlet.
Looking at the combination setting on top the tripod, I couldn't help but think that it looked like a couple of bugs in conjunction - one of those kinds where the male is much smaller than the female. No doubt the lens will eat that camera after copulation.

All in all, final thought: I'm pretty happy with the lens. It appears to me, though, either I'm not doing well at the focussing thing, or the DFA 150-450 pictures posted on this thread are just inherently sharper. See, for example ZZeitg's birds, above:

I got this one, a "prime", because I figured a "zoom" wouldn't give as sharp an image. Silly me?
