The Nikon 24mm f/3.5 TS was not available for testing, but this comparison serves two distinct purposes:
- Comparison of lens performance.
- The difference between using shift to correct perspective and using a conventional lens with the camera angled upwards.
The Rokinon 24TS is manual focus as all tilt/shift lenses necessarily are. Wide open at f/3.5 it is difficult to focus due to a hazy low contrast view which is immediately noted in Live View mode.
Nor can one hope to focus accurately by eye in the viewfinder, so use of Live View stopped down to f/4 or f/4.5 is strongly recommended; this cleans up the image enough for focusing.

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.
