Overview of Nikon and Canon GPS Units
Both Nikon and Canon offer GPS units that can be connected to their respective brand DSLRs, with recent-model DSLRs having built-in menu support with recording options.
With both brands, the GPS units are add-on devices that are designed to be mounted in the hot-shoe of the camera, though both can be mounted to a belt or otherwise with a cable.
For the Nikon GP-1 (about $195), a cable is required both to power the unit and to record data; the unit is a “dumb” unit with no electrical connection to the hot shoe; in the Canon GP-E2 case, both the Canon 5D Mark III and Canon 1D X (and perhaps other models) can use the GP-E2 cable-free with connection pins in the hot shoe taking care of connectivity.

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.
