The Vivitar 28mm f/2.8 in M42 mount is best understood not as a single lens but as a family of optics sold under Vivitar's badge — Vivitar being a marketing house (Ponder & Best) that commissioned lenses from various Japanese manufacturers rather than building them itself. The version reviewers care about, and the one most sought after in M42, is the Komine-built 'Close Focus' model. The 'Close Focus' name is not a nickname but an actual designation printed on the barrel — owners stress that it must literally say 'Close Focus' to be the right lens, because it is frequently confused with the ordinary Vivitar 28mm f/2.8. This model earned a small cult following for two reasons. First, its floating-element design lets it focus much closer than a typical wide-angle of its era — down to roughly 0.23 m for about 1:5 magnification — turning a modest 28mm into a capable close-up tool for flowers and detail work, with reviewers noting the optics are actually better up close. Second, it is a character lens: neutral, accurate colours, pleasant bokeh, and a warm, film-like glow in strong light. Community members half-affectionately note it is 'famous' for ghosting and flare — that reputation is the closest thing it has to established jargon; there is no romantic 'Bokeh King' or swirl nickname attached to it.
Verdict: This is a character-driven compact wide-angle for photographers who value rendering and close-focus versatility over corner-to-corner clinical sharpness. If you want the Komine 'Close Focus' version specifically, it rewards you with neutral colour, smooth bokeh, a warm film-like glow in strong light, and a genuinely useful near-macro reach — provided you shoot it in good light, hood it against its famous flare, stop down to f/4–5.6 for the centre, and accept soft corners. It is a poor choice for anyone needing high contrast or sharp edges wide open, but a delightful one for the vintage-look shooter and detail hunter.
Smooth, pleasant bokeh, unusually good for a compact wide-angle.
Neutral, accurate colours, though strong-light flare can add a warm cast.
Sharp in the centre from about f/3.3, peaking around f/4–5.6, with corners staying soft; notably good up close via the floating element.
Prone to dramatic flare and ghosting, 'famous' for it, so a hood is recommended.
Somewhat low contrast, so it renders best in bright light.
Some vignetting wide open that clears when stopped down.
