Today decided to go for another rain walk with the Sigma 28mm 2.8 Mini Wide. A have a sentiment for these lenses, been my first wide angle glass for Pentax K, produced late 1970s. Obviously with regards to lenses I am trapped in that period. The only reason I somehow abandoned shooting with it, is that sometimes the aperture operation mechanism used to stick, and hence one could not be sure of the exposure metering. This is related to my copy only. On a digital camera I generally have no problems, as long as I rarely change the aperture settings: on almost all lenses I shoot manual with, I leave it either 2.8 or 4. I remembered what fun was it to use it back then when I got it. Very well built, sharp in the center, smooth focus, a nice boke of the 6 blades’ aperture, and an ability to close focus down to 1:4.5. Which makes it a hot candidate for all-purpose walk around.
Sharpness might be an issue in the corners of the lenses, sometimes flare and contrast as well, if you is not mindful of the light.
All photos done with f4, ISO 400 on a Pentax K20D.
