  • Zeiss, Cosina, Sigma and Tamron – NEX E-mount future

    Sony Corporation announced today it will disclose the basic specifications of its “E-mount” for interchangeable single lens cameras, without fee, to manufacturers of lenses and mount adaptors, starting April 1st, 2011. This was previously confirmed at the photokina press conference – now they have revealed that Carl Zeiss AG, Cosina, Sigma and Tamron will all be working on the E-mount system as independent lens makers.

    “This opens the way for manufacturers of various lenses and mount adaptors to effectively develop products conforming to “E-mount” specifications”, say Sony.

    The NEX E-mount revealed – ten contacts, three flanges and a mere 18mm of register distance…

    “Users of the Sony’s NEX-3, NEX-5, NEX-VG10 and other E-mount compatible Sony digital imaging products to be launched in the future will now be able to use interchangeable lenses from both Sony and various other manufactures, while they will also be able to attach non-Sony lenses to their Sony digital imaging products via a mount adapter. Sony believes the growth of digital imaging products employing the “E-mount” will further increase the enjoyment of photography and video shooting among an even wider range of users.

    “These basic specifications will be disclosed to manufactures of lenses and mount adaptors following a predefined process of approval and the signing a license agreement with Sony.

    “As of today, the decision to disclose basic specifications of the E-mount has been endorsed by the following companies.”

    (there follow these manufacturer statements)

    Carl Zeiss AG
    As an independent lens provider, Carl Zeiss welcomes the disclosure of the E-mount specifications by Sony. It helps manufacturer’s product development, benefits customers and therefore assists in establishing E-mount as a new, healthy and strong system on the market.

    Cosina Co., Ltd.
    Cosina Co., Ltd is excited by the potential of Sony’s E-mount which enables to a large-size image sensor to be incorporated in a compact, interchangeable lens camera. We have high expectations for the E-mount with its aims to create a new photography culture, and express its assent to Sony’s decision to provide information related to E-mount.

    Sigma Corporation
    Sigma Corporation fully supports Sony’s decision to disclose basic E-mount specifications. We believe this move will spur the further growth and diversification of camera system across the industry, provide photo enthusiasts with a wealth of choice and enrich in their photographic lifestyles.

    Tamron Co., Ltd.
    Tamron Co., Ltd endorses Sony’s decision to disclose basic E-mount specifications. We aim to offer our customers new solutions and unprecedented photo-shooting enjoyment through the manufacture and sale of E-mount lenses.

    Editorial comment: at the photokina conference, the wording used seemed to imply that independent E-mount camera bodies were also a possibility. Of the makers above, three already have a history of making rangefinder or compact style large sensor bodies – Zeiss (to date, film only); Cosina (digital, in the form of the Epson Leica mount bodies with 6 megapixel Sony sensors) and Sigma (the DP-1 and 2 series have fixed lenses, but would be a natural candidate for conversion to E-mount form). If this was to be the case, in a future announcement, the E-mount would be established as an alternative to the Micro FourThirds system with a capacity to use sensors in formats between 2X and 1.5X with existing lenses, and possibly up to full frame in a secondary configuration with a different range of lenses (backwardly compatible with smaller sensors).

    Is this the same Sony people rant about being protective and exploiting their customers? No. It is Sony listening to their customers. It’s Alpha becoming the 21st century equivalent of Leica.

  • Alpha and NEX overtake Nikon UK DSLR sales

    Chris Cheeseman writes in Amateur Photographer, reporting on figures released by photo industry analysts GfK, that Sony interchangeable lens camera sales in the UK have overtaken Nikon, moving the company into second position behind Canon.

    http://www.amateurphotographer.co.uk/news/canon_and_nikon_lose_ground_as_camera_wars_hot_up_news_305118.html

    In the Japanese home market, Canon remains top, Nikon second and Sony is third with over 15% of the market share. No attempt is made by AP to analyse the importance of Sony having a market share which is roughly half that of Nikon and Cano respectively, in that market.

    The figures relate to the year 2010 – a calendar year – and it needs to be considered that Sony’s NEX system effectively went on sale slightly before midway during that term, and the SLT system one quarter later. Some Sony models were only introduced after photokina, in the final three months of the year.

    In fact, it’s almost impossible to judge Sony’s impact when 2010 is viewed as a year rather than in terms of monthly or quarterly figures. If a graph was to be drawn with four lines on it – Nikon, Canon, Sony and ‘everything else’ – it looks as if the 11% overall decline in Nikon and Canon would contrast with a steep late year climb from Sony.


  • HD videocast – NEX adaptors and odd lenses

    I’ve finally got round to trying a ‘proper’ videocast – perhaps the first of regular short demonstrations – with the Alpha 55 offering me HD filming while demonstrating the NEX-5. And I can use the NEX-5 to film stuff about the Alpha 55. A Canon 60D helped, though its inability to refocus during filming (which the NEX-5 and Alpha 55 can do) proved a small problem. The sound from the Canon was used, mainly because it had been set with a manual level, while the Sony was using an external condensor mic that pickup up some serious interference from the lights.
    The lighting is nothing more than one 30W daylight colour energy saver and one 20W – using an angle desk lamp from IKEA and a spare table lamp. The background is a Calumet (Lastolite in disguise) canvas. To do the filming, I ran a 7 inch Lilliput monitor from the HDMI output of the Alpha 55, and mounted it facing me on a bar right next to the camera. The Canon was set up as a second camera and left running from that position. Editing, including cutting and pasting the soundtrack and parts of the Canon video, was in iMovie 11.

    This is a full 1080p HD YouTube film – if you can view it (bandwidth is an issue) try the higher resolutions. The Alpha 55 consistently overheated at around 7 minutes, showing me a temperature warning then shutting off. The room was not warm and the camera screen was both not active, and moved away from the camera back. My first attempt at this film was spoiled by the overheating issue, perhaps because SSS was left on in error. However, on a tripod SSS is not active to any extent when shooting video (it does not have the same problems of creating blur, which happen with still images due to the way mirror or shutter vibration are reflected by the tripod). Previous time limited movies I’ve made have been hand held and of course SSS is both used and expected to be very active.

  • NEX-5 live sound

    I’ve been using the NEX-5 with accessory mic – and sometimes, by forgetting to bring it, without. Today we had the Ripon City Morris side in town, and I was taking still shots using the Nikon D3X with the new Nikkor 85mm f/1.4 AF-S G lens. The NEX was grabbed as an afterthought for video.
    Well, the wind noise with the built-in mics was just too much; most of my ‘footage’ ended up on the cutting room floor. After I’d got the portraits and other shots I need for the Nikon test, I nipped back to the studio and got a 4.5m high Manfrotto lighting stand fitted with a ball head. The NEX got its accessory stereo mic (set to 90° coverage) and the 16mm lens, and despite the wind level, was hoisted aloft for the last couple of dances in the square. The 30 minutes recording time really helps. My framing was not perfect, so two of the video clips were cropped down from the original 1080p, in iMovie. It is an instant process, just select the clip, select the crop tool and trim.
    Despite very definite winds blowing around the pole-mounted camera and mic, there were no wind noise issues at all. So: for outdoor shooting, the accessory mic is essential.

    Here is a video made the week before, entirely using the ECM-SST1 microphone, which has no wind noise at all – see this post: ECM-SST1 microphone handheld clips.

  • NEX-5 with ECM-SST1 mic

    Some parts of this were very close to large PA system speakers; others were close to dangerous loud instruments of war, notable Border fiddle and Scottish bagpipes from the Coldstream town pipe band (not the same as the Guards, this is the locals not their namesakes!).

    Hand-held, mic set to 90 degree coverage not 120 degree. The NEX-5 only offers auto gain, not manual control of sound of any kind. 18-55mm OSS lens, stabilised but not always in stable hands. Widely varying distances from sound source to mic.
    Hopefully a fair view of what the NEX-5 does in this kind of situation; and a view of why, despite the awful weather, I really don’t want to retire to somewhere warm and lose this place!

  • Fitting a Vectis 80-240mm to the NEX

    OVER the past few days I’ve been looking at the NEX-5 and a range of lenses and optical systems. I’ve got adaptors for C-mount (16mm/TV/CCTV) lenses, Leica 39mm screw, Minolta MD and the LA-EA1 for Alpha A-mount. The NEX-5 has proved able to provide a surprisingly bright focusing image through a classic German microscope:

    It also proved very competent with the Sigma 70-300mm f/4-5.6 OS lens, the adaptor providing power for the OS which is fully functional, and also for auto exposure, leaving only manual magnified focusing to tackle. (more…)
