The latest lens patents from Ricoh and Olympus

Ricoh filed a patent 2012128045 for 14mm f/2.5 and 19mm f/2.5 lenses (28mm and 35mm equivalent). The interesting part is that the 19mm lens is designed for an APS-C camera (the 14mm lens is for a 4/3inch sensor). It is not clear from the patent if those lenses are designed for the GXR system or for a future GR model that will come with an APS-C sensor (currently the Ricoh GR Digital IV has a 1/1.7" CCD sensor). Rico already offers 28mm f/2.5 and 50mm f/2.5 GXR units.

A new Olympus patent 2012123340 was filed in Japan for a collapsible 25mm f/2.8 macro lens:

  • Patent release date: June 28, 2012
  • Patent filing date: December 10, 2012
  • Image height: 11.15mm
  • Focal length: 24.91mm
  • Aperture: 2.86
  • Angle of view: 50.20 deg
  • Lens design: 8 lens elements in 7 groups, 1 aspherical element

    But wouldnt the 19mm be a 28mm EQ also? to have 35mm eq on a APS-C, we need a 23mm lens..am i wrong?

      Yes, you are correct.

      I’ve long thought Ricoh was headed towards a larger sensor (hopefully APS-C) in the GRD. I’ll be first in line if they do it.

    The “28mm f/2.5 A12-4″ unit currently on the market actually has an 18.3 mm lens, the “28 mm” being the FF equivalent. So the new patent would be an update, if it is for APS-C, and if it is really 19mm, rather than 19mm-equivalent .

    I suspect a 4/3′ GRD.

      I believe Michael’s post above (thanks Michael) indicates it will likely by APS-C but I could be misreading the translation. Personally I think Ricoh/Pentax will roll big and go APS. If they can pull it off, it will redefine high IQ in a compact package.

    I read somewhere that Olympus admitted to be using a Sony sensor in their OMD EM-5.

    If that’s true then a 43rds GXR seems to be a likely possibility.
    After all Ricoh’s been using Sony sensors before.

    Should be good! Would keep lenses small… :)
