Shift and Tilt Lenses
Shift lenses and tilt/shift lenses allow much more control over the photographic process by dint of a considerably larger image circle projected by the lens. A typical lens for a 35mm DSLR projects an image circle of diameter of around 44mm. A shift or tilt/shift lens typically offers an image circle of 67mm or so—more than twice as large in area.
The larger image circle allows “movements” of the lens to achieve photographic goals; the lens is oriented (shifted and/or tilted) such that the sensor/film sees the desired portion of the image circle.
Use of the tilt mechanism changes the perspective and framing slightly as with all DSLR tilt/shift lenses, due to the way the lens rotates as tilt/swing is applied. Slight compositional adjustments might have to be made following a change to the tilt/swing setting.

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.
Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.
- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
- Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
