A unique telephoto offering close focus control along with perspective control capabilities the TS-E 135mm f/4L Macro from Canon is a tilt-shift lens well-suited for studio, product, and tabletop photography. Up to +/- 10° of tilt is possible, for focus control, and +/- 12mm of shift, to adjust perspective and composition, and a tilt-locking mechanism can be used while shooting for more stability. A minimum focus distance of 1.6\' and a maximum magnification of 0.5x are also benefitted by the range of movements for more control over depth of field when photographing close-up subjects.\r\n\r\nComplementing the operation of the lens, this L-series prime is also distinguished by its optical design that features a pair of Ultra-Low Dispersion elements to significantly reduce color fringing and chromatic aberrations for high clarity. Individual elements also feature a Subwavelength Coating to suppress flare and ghosting for greater contrast and color neutrality.\r\n\r\nPerspective control, tilt-shift lens affords +/- 12mm of shift and +/- 10° of tilt, and both types of movements can be applied independently, and parallel or perpendicular to one another. Additionally, the tilt and shift functions can be rotated +/- 90° in any direction for applying the movements in distinct directions.\r\nTilt-locking mechanism and a large tilt knob benefit operation and ensure the lens stays in place while shooting.\r\nTwo Ultra-Low Dispersion (UD) elements help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.\r\nA Subwavelength Coating has been applied to lens elements to minimize surface and internal reflections for a marked reduction in lens flare and ghosting when working in strong lighting conditions.\r\nA minimum focusing distance of 1.6\' along with a maximum magnification of 0.5x benefits working with close-up subjects.\r\nRounded nine-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field techniques.
