Re: Heat waves

these are both 600mm f/6.3 shots from my tamron 150-600, with fast shutter speeds, same scene that i posted earlier, shot across a busy freeway... the "hospital san diego" text is reasonably sharp? you can still almost read the license plate numbers, but this looks like a possible heat wave problem to me... it's ooc jpeg, a nightmare compression scenario.

the alignment on the brick wall shot looks fairly close, because the bottom corners look equivalent to each other; the outer center/top corner region on the left side looks weaker, however.

the first thing you are looking for with any test shot is that the sides match each other, followed by how do the sides compare to the center.
