Kase Launches AF 150mm f/5.6 Reflex Lens with Autofocus

Autofocus on a mirror lens is genuinely new territory. Reflex lenses have always been a manual-focus oddity, so Kase adding AF to the format is a real engineering decision, not a spec sheet tick. The donut bokeh is polarising and non-negotiable on this design, so know your brief before you get excited. If you shoot events or portraits where clean backgrounds matter, this isn't your lens. If you want compact telephoto reach with a distinct visual signature for editorial or street work, it just got more usable.
