By a lot metrics in which we critique photography lenses, the CV 28 has some weaknesses for sure. Football bokeh, strong CA with strong highlights in background, structured bokeh. Its not a lens with a ton of micro-contrast and probably not a contender in the "which lens has the most pop" thread (though when you get some distance between the subject and background, there is a fair amount of it).
If I think of this like a documentary lens though, and get more into a mindset of cinematography, then the lens really evokes an old school hollywood or classic PJ look within the optics itself. I enjoyed using the lens this way
