Leica Monochrome shipping and cool video by CamerastoreTV :)

The nice team from CamerastorTV made that new Leica Monochrome video review I embedded here on top. These guys are so nice I am going to link to their store a couple of times: www.thecamerastore.com, www.thecamerastore.com, www.thecamerastore.com, www.thecamerastore.com, www.thecamerastore.com,  …and I am not going paid for this joke :)

That said I heard first preorders have now been shipped by BHphoto (Click here). But I really don’t know how few of my readers had the money to preorder this jewel. We may better wait for Sony to launch their NEX-FF hybrid system. On SonyAlphaRumors we just learned that this system works in a different way then we thought (Click here ot read the newest rumor on SAR).

Another Canon Patent For Improved Phase-Detection Autofocus (next mirrorless sensor?)

Conventional approach (left) and patented approach (right)

Egami (machine translated) spotted another patent filed by Canon and related to methods that aim to improve the performance and accuracy of the phase-detection AF. This is the second patent in a few days – the first one can be seen here. Such an AF method is featured on the Rebel T4i/650D and on Canon’s recently announced mirrorless camera, the EOS M. Note that such an AF method is particularly useful on a mirrorless camera, given that such cameras, since they are missing the mirror, can not focus in the “traditional way”.

As far as I can tell, the patent details methods to increase AF performance by eliminating problems caused by the angle of incidence of the light: “[…] reduce the diffraction limit by a high refractive index layer“. Another discussed issue is the reduction of the pixel size (higher resolution??). I am more and more confident that both patents are related to an upcoming sensor which, I guess, will be at the heart of the more pro-oriented mirrorless camera most of us are expecting to be announced in September at Photokina.

    • 2012.8.9 Release Date
    • 2011.1.20 filing date

  • The diameter of the spot light focusing of the micro lens

    • Determined by the numerical aperture and ? the wavelength of the incident light
    • By the wave nature of light, not smaller than the diffraction limit
    • When the pixel size below the diffraction limit, pupil division is impossible
    • ? = 1.22 * (? / n * sin?) diffraction limit
    • ? This angle ? is half the chance of lens optical system was synthesized in the micro-lenses and layers

  • Related art

    • There is a light flux can not reach into the openings of the light-shielding layer of the phase difference AF pixel for the image plane, the light-receiving efficiency is reduced
    • Although the distance can be shortened and the photoelectric conversion unit if microlens back-illuminated (BSI), if the pixel consists of a low refractive index layer in the layer lens +, for total internal reflection occurs, can not be expected to increase the angle

  • Canon’s patented

    • To reduce the diffraction limit by a high refractive index layer
    • Structure of the pixel

      • Within a layer lens, and light shielding layer formed between the microlens
      • The high refractive index layer, filled between the lens and the light-shielding layer in the layer
      • The low refractive index layer, a light shielding layer filled between the microlens and
      • Optical system consisting of micro-lens and lens in the layer, connecting the focal point in the PD
      • A case

        • 1.45 refractive index of the low refractive index layer
        • Layer of high refractive index lens and in the layer refractive index n = 2.3 (silica Sio 2 of the prior art is n = 1.46)

EISA award winner prize for E-M5, X PRO 1 and NX20.

The European EISA agency released the name of the winners of the 2012 awards. There are thee categories of mirrorless cameras and those are the winners:
European Compact System Camera (Winner: Olympus OM-D E-M5)
European Advanced Compact System Camera (Winner: Samsung NX20)
European Professional Compact System Camera (Winner: Fujifilm X-Pro1)

For the record, EISA uses the deifnition “Compact System Camera” instead of our more popular definition “Mirrorless”. And as it happens every year…everybody wins a price…Nikon, Canon, olympus, Panasonic, Samsung and so on :)

By the way, the best mirrorless lens is the Panasonic 12-35mm X zoom.

Sony NEX cameras hack project officially started! Olympus announcement next week…

 

Vitaly Kiselev announced the new NEX and Alpha hack project in collaboration with the hacker called “Someone1.00”. The official forum can be seen here: www.nex-hack.info. Great news for all NEX owners! And we are also curious to see how Sony will allow programmers to work on the new NEX-5R and NEX-6 cameras that are “rumored” to have Application support.

Meantime Olympus will have a new announcement next week. No big deal, we expect the 60mm macro to be released (this lens was already shown in May).

Canon patent for improved phase-detection AF (for the next Mirrorless Camera?)

Egami (machine translated) found a Canon patent for an improved phase-detection AF. Higher accuracy is obtained by better propagation of light. The patent text also suggests, the method should improve accuracy when light is falling in with a low-angle incident. Another fact is very interesting: the patent refers to smaller pixel size, i.e. you can pack more pixel on the sensor. So, given that a phase-detection AF is particularly useful on a mirrorless camera, could that indicate that Canon is working on a higher resolutions sensor (with an improved AF) for its more pro-oriented mirrorless camera that we expect to be announced later this year? I think that’s plausible. If Canon is working on a mirrorless camera that is more pro-oriented than the EOS M, this cam will most probably have a higher resolution.

  • Existing techniques

    • Conventional techniques beam separation is insufficient, Ranging Accuracy is poor

      • Scattering effects due to wiring
      • The smaller the angle of incidence, it is difficult to detect
      • Smaller pixel size, the value of F becomes larger microlenses (dark), they spread the light next to almost the same in the size of the image pixel size and pixel diffraction

Canon: The EOS-M is made for women. No plan to make FF mirrorless (for now)

Image courtesy: DC.watch.

DC.watch (Translation here) interviewed the Canon team that developed the EOS-M mirrorless camera. Here are some interesting bits from the interview:

1) From the beginning the goal was to make the EOS-M as good as other EOS DSLR cameras. And to make ir small and light.
2) First goal is to reach a 15% of the mirrorless market share in Japan (by October).
3) Shutter from the EOS DSLR series has been minaturzized to fit into the EOS-M
4) GX1 sales are still strong (production is 30.000 units per month).
5) A Four Thirds sensor would bring an even further advantage in miniaturization but Canon wanted to make it fully EOS compatible.
6) We chosed to have Phase detection pixel on sensor because that technology works better than COntrast AF on moving objects.
7) EOS-M mount can NOT accomodate a FULL FRAME sensor. And there is no plan for a FF mirrorless.
8) No plan for now to make an adpater for FD lenses.

Interesting. They also said the main target are women :)
