Pondering getting this lens for use on my R5 or RP. Has gotten some decent reviews (or at least its twin the Samyang has). I know that many use the manual focus RF 14-mm lens for astro work, but seems that the ability to also do AF expands the utility of this glass for landscape and other applications. My specific question, if anyone knows, is if when using manual focus mode on this AF lens (it is focus by wire), will the focus stay set if the camera powers down between exposures or will the focus reset to some baseline range and then need to be refocused for each shot? Back in my EF 14mm days, I could gaffer tape the focus ring once I composed and setup a shot (say Milky Way with a foreground subject) during the daylight hours than take my images after dark without need to refocus. I noticed that the RF 15-35 f/2.8 will not hold the focus when it powers off and wonder if the Rokinon behaves the same way.
Hope that makes sense. Curious to know if any of you have tried this lens.
