MonsterAdapter LA-EA4r Upgrade Kit (EA4r for short) is specifically designed to drive old Minolta/Sony A-mount body-driven autofocus lens on the Sony E-mount mirrorless camera, allowing hundreds of focus points and advanced autofocus features such as human and animal eye AF, whatever is provided by the camera.
You will need to install the EA4r circuit board provided in the package into your Sony LA-EA4 adapter, replacing the counterpart in it. The complete installation guide in both written and video will be provided for your reference.
No SSM/SAM lenses are supported after modification with this board;
Auto focus for video shooting is not supported.
So why buy this product and modify your LA-EA4 into the MonsterAdapter LA-EA4r?
It brings benefits of Sony's latest E-mount cameras to your classic A-mount screw drive AF lenses, making their revival with better experiences, which include:
-The retro rendering from 1980’s vintage lenses.
-More light and more sharpness with the translucent mirror removed.
High-precision AF by directly using the on-sensor focus algorithm from the body, no AF micro adjustment required any more.
Ultra wide AF points coverage across the frame (depends on the camera) instead of the traditional 15 points of original LA-EA4 adapter. (The Minolta/Sony AF 500mm f8 Reflex lens can expand from the single central AF point to about 80% of screen AF points coverage, it's revolutionary!)
With our product, you can enjoy features the latest mirrorless cameras can offer with your old beloved A-mount glasses.
It's much easier and more fun to shoot portraits with human or animal Eye AF tracking. Tack sharp right on the eye!!!
Fully Restorable Modification
You can easily and fully restore to the original LA-EA4 after the modification as long as you well preserve the removed board and mirror.
