well, that would be a case were I can understand feeling that you *need* to shoot wide open... managing OOF highlights is often difficult... have to work with the charactoristics of your lenses.

Most of my lenses I shoot wide open at all times.
Can not stand those polygon shapes of OoF highlites.



I was speaking kinda tongue in cheek.
However, there is one Canon lens where the EMD iris outline looks rather weird in the aperture range f/1.2 to about f/1.8. Consequently, when there are strong OoF highlites to be expected, I prefer to shoot the lens either wide open (f/1.0) or stopped down beyond f/2. Not the best lens design feature.

However, those are very singular circumstances. I do agree with you in the following way.....we all go thru a fast lens \"discovery\" process, sooner or later in our photographic experience. When I got the 85L my first thoughts were \"How sharp is it wide open ?\", \"How smooth is the bokeh wide open?\". Naturally, in pursuing answers to those questions I have taken hundreds of \"only left eye in focus\" photographs. After the novelty had worn off, I have also discovered that the lens is perhaps at its best at intermediate apertures.
