Overview of Sigma 180/2.8 and 150/2.8 APO Macro
The Sigma 35/1.4 DG HSM was impressive enough to warrant taking a look at two of Sigma’s telephoto macro lenses, the Sigma 150mm f/2.8 APO-Macro DG HSM and Sigma 180mm f/2.8 APO-Macro DG HSM.
The APO designation is always appealing, even if the meaning of APO varies by manufacturer. And for the 180mm in particular, there really is no other high performance* all-around 180mm lens out there today, unless you count the non-macro Nikon and Canon 200mm f/2 offerings. And 180mm is also enough spacing from the 135m focal length (Zeiss APO-Sonnar).

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.
