One of the big differences, however, with modern lenses is active image stabilization. Various "IS" and "VR" things in Nikon and Canon and similar lenses. Very important if shooting handheld and you want to take shots at slightly lower ISOs with less graininess in low light conditions, and for handheld videography with the same lenses. The active stabilization many modern DSLR and mirrorless market lenses is worth a few f-stops difference.
