Aperture Series: Mosaic (Pentax K-1 SuperRes + StdRes)
This finely detailed scene at far focus distance is an exceptionally demanding subject that makes mincemeat of most lenses, mercilessly revealing every weakness, lack of symmetry, etc. Most lenses require f/5.6 or f/8 to sharpen the whole mosaic.
By serendipity, Pentax K1 behavior at f/9 happens to confirm a serious image quality issue in one of the frames—shutter vibration in single-shot StdRes mode (all other frames shot in SuperRes mode).
While designed for portraits, Pentax states that the 77/1.8 is applicable for landscapes and still life. Here we put “landscape” to the test: our subject is at a uniform distance, which is often the case for a landscape scene.
The smc PENTAX FA 77mm f/1.8 Limited is specifically designed for portrait photography and accurately reproduces the tones, colors and texture of the subject's skin, clothes and accessories.

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.
