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

    DPreview says 649 USD for the module alone – that would probably be 1.000 for the kit.

    how this perform vs leica m8? used m8 for $2000 maybe better than this shoebox ricoh?

  • Stephen B

    Nice but still, the key to M photography is the viewfinder. It is that which I know and love. The many ‘digital Leica-ish’ adaptor offers out there that dangle the ‘affordable’ body substitute just let me down when it comes to focusing. I simply will not manually focus using a EVF or the LCD. I want split image focusing.

  • J Shin

    Looks more and more like Sony NEX-7 is going to be the product to beat.

  • scott

    There’s a potential problem with this: When the camera is set to a higher f-stop, there will be very little light reaching the sensor, so the LCD display used for framing would be very, very dark, correct? Other solutions on the GXR have the benefit of being able to keep the lens wide-open until the photo is taken.

      On Canon 1dsm3 you get option to display accurate exposure or boost sensor gain for best preview (I use Leica R lenses). The same idea could be applied to GXR system.

    I am still waiting for a small and reasonably priced solution for my R lenses. I guess I could get R to M adapter and evaluate the combination. I just hate when my 21mm becomes 31.5mm.

    However, if Ricoh module sells, this will open floodgates for other camera manufacturers that have been laying low and waiting. I hope this motivates Epson, Cosina and Zeiss to get back into the game.

    As for me, I would like high res electronic viewfinder with at least 10X zoom for focusing. My Canon 1dsm3 with live view works OK, but it is not for fast work, and camera is big and heavy. I have high hopes for Fuji X viewfinder system – they should have interchangeable mount system soon. Meanwhile, I will stick with Canon.

    … hopefully Ricoh would also build an affordable GR 35mm f2.0 lens to go with this highly anticipated Leica M-mount adapter…this way i am able to make a comparison with Leica or VL lens.
