#San francisco tiltshift manual#
First, the Nikon 19mm f/4E PC is a manual focus lens. Tilt-shift lenses offer many enhancements over traditional lenses, but they are expensive, not easy to use and come with a few compromises. The ability to apply selective focus on a particular part of the image via lens tilting allows distant subjects to appear “miniaturized”, although this effect can be reproduced in image editing software, as well. Focus stacking in post-processing software is another way to achieve maximum focus without stopping down excessively, however, the technique also has its pros and cons, making tilt-shift lenses unique in their own ways. Tilt-shift lenses offer an alternative to stopping down by tilting the plane of focus, putting both closest and furthest objects in focus. Stopping down to very small apertures results in diffraction, which impedes sharpness. Landscape photographers often want to keep everything in focus, especially when dealing with close foreground objects. Architecture and cityscape photographers often work with straight lines and tilt-shift lenses give the ability to avoid the convergence of vertical lines by shifting the lens upwards or downwards. “PC” stands for “Perspective Control”, but I will refer to this type of lens as “tilt-shift” in this article. This is an in-depth review of the Nikon 19mm f/4E PC, also known as PC NIKKOR 19mm f/4E ED, a special purpose wide-angle lens designed for architecture, cityscape and landscape photography.
