This page shows a simple modification that removes this linkage
while having no other effect on the camera.
Here’s the problem:|
This dimple in the aperture pointer engages the teeth on the speed ring.
To defeat this linkage, first focus the camera to its closest distance, revealing two screws supporting the aperture pointer. Carefully remove both screws and the pointer. To ensure that these screws don’t fall into the camera, I suggest unscrewing them with the camera facing lens-down, causing the screws to fall onto your work-surface.
|Here’s a rear view of the pointer. The dimple is a bump when viewed from this side. You need to remove this bump.|
Put a cutting wheel on a Dremel, and carefully grind off the bump.
Although this pointer looks large in this picture, it’s actually tiny,
so it can be hard to see where you are grinding, even when wearing close-up glasses.
So don’t rush this step.
Reinstall the pointer, and your camera will no longer have LVS. Consider putting a dab of Locktite on the threads before fastening the screws, ensuring that they won’t loosen. Shooting with your Retina will now be more enjoyable.
