well, the sensitivity is of any long lens because of, as you also say, of the motion blur and air distortion due to air movement caused by the air mass moving due to thermic fluctuation in the air between where you are and where the subject far away is.
Great picture! I’ve always like this lens which was always considered the poor relation of the 2.8 but which on a mirrorless with EVF ( which acts as an image luminnosity amplifier) has come into its own.
The lack of autofocus though ( even with the focus limiter) makes this lens very difficult to be used on dynamic subjects.

As a form of courtesy towards your fellow users of this forum, PLEASE remove the obnoxious tapatalk signature, it adds nothing to anyone’s contribution and it is only a sneaky way used by tapatalk to push their product by polluting each forum participant with promoting their products with unpaid advertising for their software and the brand of your phone. Removing it is easy and it is an act of courtesy that shows respect for all those whom are annoyed by this pointless feature. This is not a personal attack to you, the annoyance is caused by tapatalk and the phone or tablet brands, they are getting all the exposure and you gain nothing by this.
