Canon 135mm f/4L TS-E Aperture Series with Swing: Ancient Log, Oblique View
Get Canon 135mm f/4L at B&H Photo.
This aperture series shows how swing (horizontal tilt) can be used to angle the plane of focus so that a subject shot at an oblique angle can be rendered fully sharp wide open (or in some cases, fully sharp with only a little stopping down, subjects often being 3D).
Aside from evaluating the new Canon 135/4L TS-E in general, I was interested in just how good an image could be made of a subject like this, and I was not disappointed. It is not an image I could have made with a conventional 135mm lens without using focus stacking, and that would have produced a very different visual impact (much more sharpness near to far).
