500mm test shots

Somewhat recently, I acquired a Sigma 50-500 also simply called the "Bigma".  With a 10x zoom ratio, it's quite a unique lens as it offers an unmatched zoom range among all manufacturers.  One would expect such a zoom to offer pretty poor image quality.  However, I found it to be much much better than I had expected.  Actually, I find its IQ to be very descent even wide-open (f/6.3) at 500mm!  Quite an impressive performance considered the range.
Check out the samples below.  Except for the last one, they were all shot wide-open at 500mm on a Pentax K5.
