Makinon MC 28 mm f/ 2.8 (I) Lens

Solid build, but not bulky for a 1970s 28mm. For normal 28mm use at a middle aperture, it's just fine. The true hidden strength of this lens is that, at least with the two that I own, the lens flare at f/2.8 takes the form of wings forming from point light. This can be used for creative effect, and I have not seen this formed with any other lens.

Weaknesses:

At f/2.8, the image is not sharp around the edges, as one would expect from an older lens. The bokeh is not smooth, and when the background is busy as with the branches of a bush, the harshness becomes very pronounced.

Comments:

This is my absolute go-to 28mm lens for digital and film, which is why I bought it for two mounts. There are options which are certainly better for image quality, but I do like to make use of that lens flare pattern when I can.
