View Full Version : Olympus' latest patent

If you haven't already seen it, a Japanese site has highlighted a patent application by Olympus which centres around modified sensor microlenses of different heights that could help enable the efficiency of contrast detect autofocus.

I am detecting some signals that this may be linked to the promised solution for Four Thirds lens users. Anyway, the article via Google Translate can be found here:

What is your opinion on the future of FT lenses?

Do you think Olympus will replace them with mFT equivalent, or is there a need of high end FT lenses with edge detection? If not Olympus can just refresh the lenses to offer mFT mounts with contrast detect electronics and force us to refresh our system eventually. They just need to offer a slow upgrade path.

Another question in my mind: Could they build a mFT 12-60 that would be smaller and lighter, or is it physical limits that make it FT lenses and mFT lenses of same specs would end up exactly the same size and weight? The 12-40 at constant aperture is lighter and smaller so I wonder...
