  • Wow… Ricoh just discovered 12MP APS-C sensors. Watch out year 2004… here they come!

  • Adam

    Wow. The four people who own this camera would have loved this two years ago.

  • amien

    well, let me tell you that a 12MP without any aliasing filter, & APSC beeing, would be sharper than any 18MP actual canon sensor. People are totally misleading when thinking that overcrowded small pixels on a small sensor could do the trick.

    The real alchemy is a perfect combination between “fat” pixels, no AA filter (or very weak) & sharp lenses !

    • boris


    • I don’t know about you, but I have a 15MP APS-C (50D) with the AA filter removed… and no, you don’t get any more detail.

      AA filters soften images only when they’re too strong, like in the case of the D3/D700 (vs. 5D)… not sure about D3s.

      The removal of an AA filter also doesn’t help because you can’t overcome the loss of resolution because of the Bayer CFA design.

      Also the 12MP is better than 18MP, etc. talk is plain wrong. A decent 18MP will always produce better 12MP images than a native 12MP sensor. So what do you lose then?

      • amien

        18MP on APS= very early diaphragmatic diffraction, all actual cameras on the market prove this point. My 18MP camera, while producing more “inner details” (textures) is out-resolved by my smaller 10MP CCD in terms of border sharpness, especially above F10 & at lower speeds.

        Regarding your 15MP camera, I really dont know which one you are talking about, there’s no bayer sensored 15Mp on the market (maybe I am wrong).
        They are 14mp, 16mp, 18mp but no 15mp… If you dont see any difference between the one without AA filter, it means there’s something wrong with your sensor, camera or glass.

        Mine clearly shows a huge difference. But moire may be a problem sometimes.

        • amien

          oh I see, 50D… sorry !

          Well, let me just ad that canon has a very poor raw development software, even if it is free. (I work with 3 brands)

        • I don’t know why I even bother to explain things….

  • If this comes in at less than 1.000 USD – which I would guess from the current GXR prices – the Leica Community would be all over it. Including me 🙂

    • Bob

      Count me out. One half of the Leica equation is the rangefinder focusing and body form. I could use the Ricoh but then lose out rangefinder focusing, direct manual controls, have to resort to stop down metering, etc. I’d rather use an M8, even with all its limitations and bugs, or the Sony NEX which is cheaper and better sensor-wise.

  • Jonathan

    Wouldn’t it make a lot more sense to buy a Sony NEX-5 ($544) + adapter ($10)?

    • Nathan

      Shhhh, remember that we’re trying really hard to keep Ricoh relevant. Don’t anger the Riconistas. Make no mention of their complete obscurity and overpriced nature. We are after all talking about people using Leica M glass on a Ricoh, here, so don’t expect discourse to be rational.

  • lynn

    why would anyone want to uglify their leicas?

    • That’s partly the point. 🙂

  • Zeusman

    Seems interesting. Agree that the no AA filter will help make for some super sharp images. Will wait to see how it handles manual focus.

    In the meantime, the NEX 5 with adapter and focus peaking works really well and that tilting screen is like shooting a an old TLR. Very cool!

    But the soon to be announced NEX 7 may steal this Ricoh’s thunder shortly.

    • Agree that the no AA filter will help make for some super sharp images.

      Where do you get your facts from? Better re check.

  • Bob

    Let’s see–no rangefinder, no way to focus other than arms-stretched-out-and-squint-in-sunlight LCD; and to top it off, stop down the lens for actual metering and shooting! How inconvenient and ultra-slow. Great for those taking pictures of brick walls and paint drying. Not useful for anyone shooting with any kind of movement.

    I’ve got a great idea–for not much more than the Ricoh body and module (in terms of Leica prices, mind you), I could buy a used M8 and get rangefinder focusing and not have to stop the lens down to shoot. Now that’s a novel idea.
