Shift lens

[David Oswald]

I just noticed a 28mm Pentax shift lens on eBay.  I've always wondered 
about this lens (but not enough to shell out the cash).  It seems that 
nowadays, in the digital age, a shift lens *may* be one of those things 
that has become obsolete.  Are they still getting use like they did 
"back in the day"?

Just curious...
