My most recent prime lens focal length concentrations have been 35mm, then 50mm, then 45mm and now back to 28mm. The three longer focal lengths seem to not be that different and moving a few feet forward or backward, when that's possible, can compensate for the focal length difference. All three can be considered a relatively "normal" focal length.
28mm, however, feels different in that it is clearly over the borderline between normal and wide angle. Objects that can fill the foreground with the longer lenses move backward at 28mm. Foreground subjects either need to be larger or closer. And yes, readjusting is the right word. I had this lens a couple of summers ago and used it a lot but haven't concentrated on the focal length since then.
Earlier today, I parked along the Mohawk River under the Twin Bridges, formally known as the Thaddeus Kosciusko Bridge, and followed a bike/hiking path into the Vischer Ferry Nature & Historic Preserve. All of these images are made with the RF 28mm pancake lens,
