Bought my copy somewhere in the very early 80's to complement my standard 'Trinity' set of the 2/28, 1.4?50mm and 2.5/105mm (another iconic lens had, and in this case even sold to get a 2/85 as I hardly ever managed to get a sharp image with it, probably due to my shooting technique using it hand held with shutter speeds of around 1/60th and under)
To be quite honest, with apologies in advance for the heresy, never saw the exceptional qualities of the lens so many rave about

.
Simply bought it to have a wide angle lens, and used it under circumstances where he focal length was useful/mandatory, like eg PJ work, events or (wedding) receptions etc
Sturdy, well built lens though, dropped mine several times on concrete/tiled floors, even to the point the 'rabit ears' broke of, never saw ant negative result on the optical quality nevertheless. It nowadays is part of my 'stable' of pre Ai and Ai manual glass I assembled over the years and started (re) using with in particular my DF
Recently even added a pre Ai early Gauss 2.5/105mm I found in A+ condition for a bottom price, hope for better results with the higher ISO the DF allows
Back in those days already tried my hand at fashion, and following the taste of that period preferred out of focus backgrounds, which of course is a bit of a challenge with a 28mm, even when used wide open
Here's one of the rare pictures I shot using it that way, shot in the early 80's at the site of the then still under construction of the Ministry of Foreign Affairs in The Hague, nicknamed 'De Apenrots' (the monkey island, as it resembles more or less similar looking constructions you often find at zoo's) by the locals
