    It looks like Panasonic is moving to merge SLR features with video camcorder features. This might make an interesting follow-up to the GH series, or a new line of camcorders using m4/3 lenses.

    I have lots of problems with current camcorders. I have large hands and nearly all models are way too small. I’m not a fan of video in dSLRs, but a camcorder with an SLR-style grip gets my attention. Add a “large” sensor (4/3 or APS-C) and interchangeable lenses and you’ve got a winner. Well, only if you don’t forget headphone jack, mic jack, etc…

  • So we will see in some point in future (and I think not to far away from now) a foveon-like sensor from Canon and Samsung.

    I Think this is good because we’re not far away from moment when limits of bayer CMOS will be reached.

  • Good for Samsung. Call it a “Soveon X3”. BTW, did you know Samsung means “3-star”?

    1. Sony filed a foveon-like sensor patent about 18 months ago, so we’ll see if anything comes of these projects.

    2. The Sony patent for a new 50 1.4 MAY indicate that Sony is working towards getting a range of prime lenses ready for their new FF projects that many feel will be have pixel counts in the MF range.

    3. Luminous Landscape published an interesting article on the future of imaging devices, and they feel Sony and Panasonic will be leading the way.
