Latest Review Posted | SMC Pentax-M 28mm F3.5 First, the biggest drawback of the lens: vignetting. In less than ideally lit situations (ie, most natural light shots I take), the lens vignettes noticeably until F8. That's fine, since one of the benefits of this lens is depth of field. Relative lack of bokeh could be considered a downside, but it is a wide-angle lens, so that cannot count as a weakness to me. Aberrations are also noticeable, but it is an M series lens, so it is expected.
The lens works very well with both the K1 and K3 iii. With FF, it is a nice perspective lens for landscapes, and distortion is acceptable for my purposes. With APS, the lens does a creditable job of being a quasi-macro lens, and an excellent job when reverse mounted.
Given price, age, and design, this lens works at least as well as one might expect.
Sample photos below. I will note that post-processing is used in three of the four linked images, but sharpness adjustments are minimal. (Contrast and saturation are often more in need of boosting.) The reverse mounted shot is unaltered.
