  1. The world’s first and only AF adapter for K Mount! It’s equipped with dual motors for screw-drive AF and iris control from the camera body.*1
  2. Designed for full frame, offering options of more than 10 e mount camera bodies for KAF lens users.
  3. Unleashs full potentials of KAF lenses with the most advanced PDAF capability from mirrorless bodies. With the reliable AF accuracy, you may be surprised by the sharpness of your old lenses like never before.
  4. Allows the bodies’ powerful PDAF capabilities*2 to work with KAF lenses, opening a whole new world for users with
    1. much larger AF points coverage across the frame;
    2. human & animal eye-focusing;
    3. AI-assisted continuous auto focus (AF-C) with high frame rates like 10-30 fps, whatever is offered by the mirrorless body;
  5. Compatible with KAF、KAF2、KAF3、KAF4 lenses.*3
  6. With built-in contacts, it can automatically recognize the lens mounted and transfer EXIF to the camera body.

Note: Because of the limits of the old screw-drive lenses like AF noise and power consumption, LA-KE1 is designed for still shooting only and its most features are not available when shooting videos.

Full featured K-mount

With K-mount communication contacts, power contacts and AF switch. the LA-KE1 adapter is compatible with K-mount lenses from KAF to KAF4, maximizing the lens compatibility.

 

Dual built-in motors

LA-KE1 has both built-in aperture motor and screw-drive AF motor, allowing K-mount lenses to achieve auto focus and auto exposure on mirrorless cameras. It can automatically recognize and control traditional mechanical aperture and KAF4 electromagnetic aperture as well as traditional screwdriver focus lens and SDM/DC/PLM motor lens.

Note: AF support for SDM/DC/PLM lenses will be provided in subsequent firmware.

 

 One Piece

Metal integral molding

The main body of LA-KE1 adopts a metal integral molding process to ensure the durability of the adapter.

 

No bokeh cut

The internal space of the adapter is optimally maximized so that the bokeh won’t be cut when large-aperture lenses are in use.

Unique Focus Mode Selection switch

For lenses like smc DA* Pentax 200mm f2.8 SDM, they both have an SDM motor and a screwdriver focusing mechanism. The AF drive mode can be selected via this switch in case the SDM motor fails. The position 1 is screwdriver, and the position 2 is SDM.

Note: This switch is only valid for lenses with dual drives.

 

Lightweight design

Can you imagine this is an adapter with only 96 grams (0.2lb)? Even less than 1/3 of a can of soda. The lightweight design of LA-KE1 will save you the weight of one extra K-mount lens in your backpack.

 


Upgrade firmware via camera

The adapter firmware will be upgraded through camera body like the same you do with native lenses so there is no USB port on the adapter through which the water and dust may get in.

      Note: For lenses not in the supported list, their performance cannot be used as the basis for return or exchange.

      *1. If the lens is with the aperture ring, it needs to be put on “A” mode to allow the adapter to work properly with AF, otherwise the adapter will only allow MF.
      *2. What exactly the PDAF related capabilities are available will depend on the body being used with the adapter. Please refer to the camera manual for detailed information.
      *3. The adapter will support the screw-drive AF and mechanic lever aperture control lenses (F, FA, DA, DFA series) first, and through firmware updates, it will later support the motorized AF lenses (SDM, DC) and the electromagnetic aperture lenses. And, the older A and M series lenses will not be supported.
