it seems that we just naturally gravitate towards certain focal lengths; even with a zoom, we tend to choose prime focal lengths more so than we choose non prime.
I always find it interesting to look at the focal lengths of my photoshoots, I find it amazing just how often they do gravitate towards primal focal lengths. But then again, there are lies, damned lies, and statistics!
Few would debate that there are certain focal lengths that work well for certain types of shots. But my original question was really about why the standard focal lengths are PRECISELY 24/35/50/85mm, and not +/- 5mm off of those lengths.
They are not precisely 24/35/50/85 .... they are just labelled that way by the manufacturer for easy marketing I suspect. They are all off by a bit. Zoom ranges can be quite a bit off.
