Manual
mode was used, the only control is your speed, easy to do, shoot a general image to get a starting point say at a 400th then 350th and 250th look at the images on your camera screen and work around your best exposure, do 2 or 3 different exposures in raw, the same applies if shooting in the shade but you will be around 80th or 100th all of the above was based on using 250iso.
Test look ajust test look ajust and shoot....... when you have done this once or twice it is easy. Just the same as using a manual camera. Try using your current lenses on manual a good exercise

PS I only use manual
mode. I have shot this way all my life and it is now second nature to do.
