While I was preparing this review, a subscriber wrote to say:
That leaves me puzzled when you complain about lens distortion, which can be corrected by Photoshop, DxO Optics Pro, and Capture NX2. I would also like to buy perfect lenses at a reasonable price, but I do not believe that will happen anytime soon... I am more interested in getting satisfactory photos using these tools .
That claim is true, but it is also not true, depending on context. It all depends, as I’ll explain here. Also, a “satisfactory” image is in the eye of the beholder.
Why I cover distortion in lenses
When I review lenses, I emphasize any lens traits that I feel might be of particular concern to at least some segment of the photographer population— the fact that some other segment might not care is irrelevant; I must point out lens behavior of any kind that is worth noting so as to be useful to a broad range of photographers, because it really matters for some photographers.

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.
