LA-KE1 - Pentax K-mount lenses to Sony E-mount cameras adapter (FW v05)

Increased sharpness with your Vintage lenses

Your K-mount lenses now gets more sharper! By using cutting edge On-Sensor-Phase-Detection-AF technology of mirrorless cameras, screw driven lenses can get more precise AF results than before.

A7C + LA-KE1 + smc PENTAX-FA 43mm F1.9 Limited wide open

Extended Focus Point Coverage

The coverage of the focus point has been extended to almost full screen, allowing you to create more with freedom.

Human/pet's eye tracking

Now K-mount lenses can also achieve tracking on the eyes of people and pets, allowing the subject to look more brilliant in the photos.

Continuous AF and AE

LA-KE1 can make K-mount lenses achieve AF and AE continuously when shooting at a maximum of about 30 frames per second (camera support required) and the focusing accuracy will be highly improved at high-speed AFC mode

Shooting with Stabilization

The camera body will automatically enable 5-axis anti-shake stabilization while shooting, just like SR function on K-mount bodies.

G Driver II empowered

G Driver is MonsterAdapter's AF driver algorithm that provides faster, more accurate AF on available cameras. Based on MonsterAdapter's own tests, the firmware containing the G Driver can shorten the focusing time by an average of 25% and a maximum of 60% compared to the previous firmware.

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

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.
