World’s First AF Reflex Lens for Mirrorless Systems… Ultra-compact Design Reduces Burden for Telephoto Photography
The 'Mirror Lens' (Reflex Lens), beloved by enthusiasts for its classic bokeh, has returned with cutting-edge technology. Kase, a specialist in optical accessories, has officially announced the ‘Kase 150mm f/5.6 AF Reflex’ lens for Nikon Z-mount and has commenced global pre-orders.
■ Overcoming Manual Limitations with Innovative AF
The most striking feature of this new product is its successful integration of Autofocus (AF), overcoming the "manual focus" limitation that was a chronic inconvenience of traditional reflex lenses. Equipped with an ultrasonic motor, it provides fast and accurate AF within the Nikon Z mirrorless ecosystem. This allows photographers to effortlessly capture the unique aesthetic of a reflex lens in candid snapshots or video recording.
■ Distinctive 'Donut Bokeh' and Superior Portability
The 'Donut Bokeh', an exclusive hallmark of reflex lenses, creates a dreamlike atmosphere with light orbs that have a hollow center—an effect unattainable with standard lenses.
Furthermore, thanks to the internal reflective structure, the lens remains remarkably compact despite its 150mm telephoto focal length.
- Optical Design: 5 elements in 4 groups (including the reflective structure).
- Build Quality: Constructed from aircraft-grade aluminum alloy, it maintains a lightweight profile while ensuring high durability.
■ Enhanced User Convenience
The lens also features digital-age conveniences. A built-in USB-C port allows for direct firmware updates to ensure compatibility with the latest camera bodies without the need for a separate docking station. Additionally, it features a 58mm filter thread for easy use with various filters.
■ Market Availability
The Kase 150mm f/5.6 AF Reflex is priced at $649 USD. Pre-orders are currently being accepted through major optical retailers, and the lens is expected to be a compelling new alternative for Nikon Z-mount users seeking a unique telephoto experience.
