  1. The 'look' is shallower depth of field. This is most relevant with medium wide angles. You can't reproduce the look of a 35mm f/1.4 on fullframe on a smaller sensor. To get the same look (when shooting the same subject, from the same distant, with the same framing), you would need something like a 23mm f/1.0. This lens does not exist for aps-c and if it would, it would be crazy expensive.

    This article gives nice examples, comparing Fujifilm aps-c to fullframe: http://andrewvanbeek.com/fuji-x-lenses-and-full-frame/
    It's about photography, but applies to video too.

    Also, full frame sensors generate less noise and typically have better dynamic range. But this isn't usually what people refer to when mentioning the full frame look.

    Important point: you don't need the full frame look to get the 'cinema' look, since most professional film cameras are using a S35 sensor, which is the same as aps-c. On top of that, most films are not shot at wide apertures like f/1.4 because it's very difficult to keep an actor in focus with a super small depth of field.


     

  2. Here's an example of what I'm talking about...

    http://www.dxomark.com/Cameras/Compare/Side-by-side/Nikon-D3300-versus-Canon-EOS-1Dx___928_753

    Nikon D3300 ($399) vs 1D X ($6999)

    Same score for both - 82.

    Now find other odd results and do a test... take a real world shot with both cameras and look at colour, feel, noise, general performance, etc. Post the results on here.

    I will be doing.

    ​DxO doesn't test 'feel' or 'general performance'.... ;) Also, I don't think anyone can just look at color and say: camera A is better than camera B. That just comes down to personal preference and/or image processing, not something like actual bit depth.

    You can disagree with the 'total' score of DxO, but just click trough to the tab 'measurements' and compare all the details.

    An article on 'how to read DxO scores' would be helpful for a lot of people though :) It's important to look further than the total score and decide for yourself what is important for your photography (and photography only, DxO Mark is completely irrelevant for video).

  3. Quick unscientific test (no tripod, not the same focal lenght, because of extra 4K cropfactor with GH4). Shot with GH4 and 14-42mm f/3.5-5.6 II kit lens that resolves 7 megapixels according to DxO Mark. Lens set at f/4 - pretty much wide open.

    All 100% crops. 100MBPS UHD and 100MBPS 1080p. Same settings. Cine-D sharpness -5.

  4. I must re affirm that I know that pretty much any lens will deliver when closed to f8-f11, but what i mean is with regard to use of lenses when near their wide open aperture - which tends to be where I'm at most of the time.  f2.8 or wider on full frame.  Now the otus lenses will deliver the required resolution for a d800e or a7r 36mpx even at f2.8.  but very few others do on paper.  Is it resolution gains we're seeing or is it simply a placebo?  If I shoot a landscape shot (36mpx still) on the a7r i'll be at f11 with a tripod and at f11 most lenses don;t quite deliver the required resolution.  at f2.8 it's like mush.    

    ​At f/11 you are already losing sharpness due to diffraction on high megapixel cameras like the A7R. You don't have to stop down modern lenses that far to reach the best sharpness levels. A lot of high end zooms (such as the Canon 24-70mm f/2.8 II, 70-200mm f/2.8 II, 70-200mm f/4L IS, Tamron SP 70-200mm VC, Sigma 18-35mm 1.8 Art) perform very well at maximum aperture or closed down just one stop.

    Look at the Sigma 18-35mm 1.8 for example: http://slrgear.com/reviews/showproduct.php?product=1609
    Popular with micro four thirds users. Sharpness is excellent at maximum aperture in the center. No need to stop down.

    Primes even more so. Look at the blur index for a Canon 300mm f/2.8L II for example: http://slrgear.com/reviews/zproducts/canon300f28lis2usm/ff/tloader.htm) pretty much excellent wide open. You don't have to buy an Otus or a super expensive Canon tele. The Sigma 50mm 1.4 Art comes very close. The cheap AF-S Nikkor 85mm f/1.8 is one of the sharpest lenses for Nikon, etc.

    I don't consider the Helios a typical lens. Wide open it is pretty bad in terms of sharpness. Modern lenses are a lot better in that regard.

    Anyway, Rich, you should rent/borrow an Atomos and see for yourself. Once you've seen the beauty of 4K, it's hard to go back imo.

  5. Cool! I don't know of any cameras that have the same amount of noise at 5000 ISO as 800 ISO. I wonder how it compares to the C300/500 and FS7/F5 when both set to 800ISO and 5000ISO. These cameras are also very sensitive just by using normal gain, so this comparison would tell us if there's a point of this sensor technology. 

     

    Agreed. It's hard to say from the video because it's a video of a video... but iso 4000 (with gain applied from base iso) looks bad on this camera. On a A7S for example iso values like that are perfectly usable.

     

    Interesting technique though.

  6. @ andy and the guys that oppose the filters
    i can see how the uv/ir is useless to most of you, especially friends from the UK

    the overcast skies offer that protection and its not needed, there is no better filter than the clouds

    the light where i am living is very different, with the exception of 3 winter months, i cant leave my house without my tiffen vND
    everything gets burned here below f4 for most of the day.
    summer is a nightmare...from 13:00-16:00 the UV is off the charts

    if you have the time check this interview from NAB for tiffen, icheck at 08:36 the "ill fix it all in post"

  7. And you'd break $300 on it without even seeing proof of that effect?

     

    I don't believe in UV filters. IR is pointless, unless you are using a camera that is over-sensitive to IR, like the Leica M8.

     

     

    Also, regarding Heliopan vs Hoya vs B&W etc. Check this:

     

    http://www.lenstip.com/113.4-article-UV_filters_test_Description_of_the_results_and_summary.html

     

    I'm not saying Heliopan is bad. But you can't just judge a filter on the brand name. It's hard to find really thorough reviews of this kinda stuff, but lenstip does this well.

  8. Just be happy with the discount. If this was a big company selling stuff, or a price of lets say €3000.... - I'd say push hard! That's not the case at all.

     

    The original asking price seems very fair. I haven't 'subscribed' to the list even though I'm really interested in this product. I'll gladly pay the full price if it delivers on it's promises.

  9. The camera has had a Japanese-only announcement which is a little odd but I fully expect the rest of the world will get it soon. The price in Japan is around the same as the A7 was at launch so approximately 1300 euros.

     

    Kinda looks like they tried to cut down on the leaks/rumors. Seems lik no websites have had the camera or even the press release under NDA. Even local Sony sites didnt have the info / website content. Worked out pretty well, nobody suspected this camera untill yesterday. And even then the leak was from Japan (digicame-info)...

     

    It is a global release though. Press release is online now at Sony EU. Available in europe in January.

     

    Price will be €1800 body  / €2100 kit (28-70mm OSS) - says Sony Netherlands.

  10. Full press release:

     

     

     

    Sony Introduces the α7 II, the World's First Full-Frame Camera with Optical 5-Axis Image Stabilization

    ,

     

     

     

     

    Sony has released the α7 II (ILCE-7M2), the next in the α7 series of interchangeable-lens models and the world’s first1 camera with optical 5-axis image stabilization designed for a full-frame image sensor.

    The camera offers outstanding image quality in a compact size and light build, and it carries on the traditions of the α7 series, which includes the world’s smallest and lightest interchangeable-lens full-frame camera (α7R). A 24.3 effective megapixel 35 mm full-frame Exmor® CMOS sensor moves along five axes to compensate for camera shake, providing optical image stabilization equivalent to up to 4.5 steps faster shutter speed of correction2 for still images. Shooting sharp handheld stills and video is now possible under conditions that may have required a tripod in the past. In this and other scenarios, users can enjoy beautifully rendered images from the full-frame sensor with the convenience of image stabilization. In-camera image stabilization also offers sharper images for those using A-mount lenses on an optional lens adapter.

    1  Among 35 mm full-frame interchangeable-lens cameras, according to Sony research as of November 2014.

    2  Based on CIPA standards. Compensates for angular shake (pitch and yaw). Measured using a Sonnar T* FE 55mm F1.8 ZA lens, with long exposure noise reduction off.

     

     

    ◠Main Features of the α7 II

    1. World’s first1 full-frame camera with optical 5-axis image stabilization

    Detects and corrects various camera shake along five axes for still images and video, including angular shake (pitch and yaw) that tends to occur when shooting with a telephoto lens, shift shake (along the X and Y axes) that becomes noticeable as photographing magnification increases, and rotational shake (roll) that often affects shots at night or when recording video.

    The full-frame image sensor moves to compensate for these kinds of camera shake. For still images, stabilization is equivalent to up to 4.5 steps faster shutter speed of correction.2

     

    Optical 5-axis image stabilization ideal for a variety of αTM lenses3

    Handheld low-light shooting at slower shutter speeds becomes possible, allowing for greater creativity and mobility without the need for a tripod. The camera’s in-body image stabilization is therefore effective even in combination with E-mount lenses without Optical SteadyShot (OSS). For A-mount lenses as well (using an optional mount adapter such as LA-EA4 or LA-EA3), camera shake is compensated for along five axes within the camera body. Users can thus make the most of the beautiful rendering power of various α lenses with the α7 II.

    3  Some lenses are not compatible with 5-axis image stabilization.

     

    Verify image stabilization results with live view functionality

    Monitor the corrected image in real-time on the camera’s LCD screen or in the OLED viewfinder, thus allowing for fine-tuned framing and focusing even when using a telephoto or macro lens.

     

    1. Speedy, accurate autofocus with Fast Hybrid AF

    Wide AF coverage with the employment of a 117-point focal plane phase-detection AF sensor (in combination with a 25-point contrast detection AF points)

    117-point focal plane phase-detection AF sensor and 25 contrast detection AF points are placed over a wide area of the screen, making use of the superb tracking capabilities of the phase detection AF and therefore enabling clear capture of moving subjects that might otherwise evade focus.

     

    30% faster AF responsiveness4

    A more advanced algorithm is used to detect the subject position, enabling optimal lens drive. In a variety of scenarios, autofocus is very responsive – 30% faster than in previous models.4

     

    1.5 times the tracking ability of previous models4 with an improved motion-prediction algorithm

    An improved, original Sony algorithm for the prediction of moving bodies results in a 1.5 times improvement in performance in tracking a subject and predicting its next movement. Additionally, AF and automatic exposure (AE) continue to track the subject during high-speed continuous shooting (up to 5 fps), so that a sudden movement or expression of the subject is never missed. Finally, greatly improved tracking ability and subject capture are made possible through the advances in image analysis technology with “lock-on AF,†a feature that optimizes focusing on the subject in accordance with its size.

    4  Compared to the α7. Based on Sony’s internal metrics.

     

    1. Superior image quality and enriched video recording functionalities with the full-frame sensor and BIONZ XTM image processing engine

    35 mm full-frame Exmor CMOS sensor for high resolution and sensitivity, with minimal noise

    The camera is equipped with a full-frame Exmor CMOS image sensor with approximately 24.3 effective megapixels. High resolution and larger pixels enhance sensitivity and reduce image noise to release the full potential of lens’ optical performance. Images are rendered beautifully and bokeh effects attainable only with full-frame sensors become possible.

     

    BIONZ X image processing engine for superb detail and natural textures, less noise

    Loaded with an advanced BIONZ X image processing engine. The fast processing enabled by this engine enhances images in several ways, through “detail reproduction technology,†which recreates natural-looking textures even in the minute details of an image; “diffraction-reducing technology,†which prevents loss of detail when aperture stopped down; and “area-specific noise reduction,†which greatly reduces noise while maintaining exceptional detail and texture even under low light conditions such as nighttime and indoors.

     

    Supports high bit rate XAVC-S recording

    In addition to recording in AVCHD Ver. 2.0 Full HD (1920×1080) 60p (50p)/60i (50i)/24p, the camera records in XAVC-S, a consumer format derived from the professional XAVC® format.5 This offers outstanding Full HD video quality at a high bit rate of 50 Mbps. Long GOP compression is used, targeting differences between frames, along with the MPEG-4 AVC/H.264 codec for video. Regarding audio recording, linear PCM is used and files are saved in the MP4 format.

    5  XAVC-S recording requires an SDXC memory card rated at Class 10 or higher.

     

    Full-featured video recording that suits professional workflows

    Picture profiles enable convenient in-camera tone adjustment. The α7 II also supports the S-Log26 gamma function, which preserves a wide dynamic range, and a wide S-Gamut mode. Other features include Time Code/User Bit (useful in editing), Rec Control (for synced recording with compatible external recorders), marker display/settings, and dual video recording.

    6  S-Log2: Original Sony gamma curve designed for HDR recording. Even under conditions when detail would otherwise be lost in highlights or shadows, images can be edited to recover detail.

     

     

    1. Enhanced usability and reliability

    Refined usability

    Grip shape and height keep the camera steady even when using a large telephoto lens. The shutter button has been shifted toward the front, to a position that feels more natural. This, along with the button’s increased size, helps reduce camera shake. Shooting comfort and convenience were a priority in design. Ten customizable buttons can be assigned to any of 56 functions.

    The tilting display features a White MagicTM LCD screen for exceptional visibility even under bright sunlight.

     

    Sharp, high-contrast XGA OLED Tru-Finderâ„¢ viewfinder for accurate previewing

    An XGA OLED Tru-Finder viewfinder with a 2.36 million dot equivalent resolution and high contrast, enabling faithful reproduction of setting adjustments, fine-tuned focusing using magnified display or peaking features, and bokeh effects. The viewfinder also allows for clear review of previous shots. Because the camera is fully APS-C-compatible, it displays the entire view even when APS-C lenses are used.

     

    Reliability that professionals can appreciate

    Sturdy magnesium alloy construction of the top, front cover, and internal structures ensures that the camera is both durable and light. The robust mounting structure easily handles large telephoto lenses, heavy video lenses, and many others.

    Main buttons and dials are also sealed to help keep out moisture and dust, and an interlocking double layered construction of media and port covers as well as body seams ensures greater moisture and dust resistance. Overall, the camera is designed to be used by photographers in any number of situations without having to worry about the safety of their cameras.

     

    Quick startup time – 40% faster4

    After the camera is switched on, it is ready to shoot 40% sooner than current models.4

     

     

    1. Wi-Fi and NFC enabled for connectivity with mobile devices; support for PlayMemories Camera Apps that allow the camera to evolve even further

     Wi-Fi and NFC connectivity for mobile linking

     Features can be expanded with PlayMemories Camera Apps

    By installing an updated Lens Compensation app (enabling the storage of lens information in Exif data, compensation of recorded video, and import/export of lens compensation values), users can manually set correction values for lens peripheral shading, chromatic aberration, and distortion.
