  • DJI Mavic Pro - Rent it out in Chennai soon

    The Mavic from DJI packs features you once thought possible only on much larger platforms into a compact quadcopter that is snappy, agile, and captures high-resolution images. The drone features an advanced flight control system that draws on a host of sensors — including a ground-facing camera, ultrasound, GPS, dual redundant IMUs, and more — to keep track of where it is flying in 3D space and even avoid collisions.

    The Mavic works in tandem with DJI's GO mobile app for accessing settings, getting a telemetry readout, viewing a low-latency video feed, and even editing and sharing your footage. In addition traditional joystick style controls, you can fly with simple tap-based commands, and the Mavic can even recognize gestures for the perfect selfie.

    Info shared from kenrockwell.com

    The Canon 5D Mark IV is the world's most universally useful DSLR. It is competitive for both sports and action as well as for wedding, nature, portrait, landscape and product photography.

    With 7 FPS on tap, the 5D Mk IV is fast enough for just about anything other than dedicated full-time sports coverage.

    With 30 full-frame megapixels, it's state of the art in resolution as well. Nikon's highest resolution camera today, the old D810 from 2014, has essentially the same resolution, but only runs at 5 FPS. The only camera with significantly more resolution than this 5D Mk IV is Canon's 5DS and 5DSR, which is essentially a higher resolution but slower version of this 5D Mk IV.

    This is why I'm so impressed that Canon chose to introduce the 5D Mk IV. Canon already has all this covered in other cameras: the 5D Mk III runs at 6 FPS and the 5DSR has more resolution. The 5D series sells only a fraction as much as the lower priced cameras, so we ought to be glad that Canon actively develops new models here at all. Nikon hasn't introduced anything really new since about 2007. Introducing this new 5D Mk IV does more for us than it does for Canon; if anything it eats into Canon's existing 5DS and 7D Mk II sales. The 5D Mk IV is essentially an upgraded blending of various other 5D series features, giving us the fastest 5D or 6D series camera ever, with almost as much resolution as the top-line 5DSR.

  • Nikon d500 - fastest DX camera ever from Nikon

    It’s a compact powerhouse fusing the highest performance of Nikon’s professional D5 with the unique agility of the DX format. Portable and powerful, the D500 will galvanize the way you shoot stills and video.

    The Nikon D500 is the fastest DX camera ever from Nikon: 10 frames per second. It is the first consumer Nikon that's worthwhile considering for serious sports shooting.

    Nikon d500 will also be available for rent soon when its out for sale .

    It has the same AF system as the D5, which is pretty hot.As expected, it has more AF points than ever before, but you can't select them all. You have only 55 selectable points, even if there are a claimed 153 AF points hidden somewhere.The bizarre part is that we lose our second SD card slot. It's been replaced with an XQD slot instead, leaving us with only one SD slot.

    It ships in March 2016 — but only to those who order it today and get the first ones. If you wait until tomorrow, it may be quite a while until Nikon can make enough of these to fill all the orders for the latecomers. With the Internet, the order que fills within hours.

    Missing

    ● No exposure MODE button near the shutter release; it's been moved off to the left side of the camera and an ISO button appears in its place.

    ● No lock on power switch; easy to knock on or off by accident and miss shots.

    ● Only 20 MP (5,568 x 3,712 pixels native); you still have to buy a D810 for high resolution.

    ● No auto brightness control for the LCD. The D4s has this.

    ● Still no full-frame AF; it may have a lot of points, but they're all in the center of the image.

    ● No Wi-Fi unless you buy something.

    ● Still no sane replacement of Nikon's idiotic Custom Settings Banks, which has been a core incompetancy of Nikon since they introduced these in 2003. There are no U1, U2, U3 (or C1, C2, C3 or M1, M2, M3 etc.) modes so we can save and recall camera settings. As-is, there is no way to save camera settings immediately; the Custom Banks

    As expected, it has more AF points than before, but you can't select them all. You have only 55 selectable points, even if there are a claimed 153 AF points hidden somewhere.

    It ships in March 2016 in two versions (CF-card version or XQD-card-version) — but only to those who order it today and get the first ones. If you wait until tomorrow, it may be quite a while until Nikon can make enough of these to fill all the orders for the latecomers. With the Internet, the order que fills within hours.

    The genuinely hot and new cameras like this always have people who wait a few days and then can't get them for their summer vacations. With the Internet, the order que fills fast and waiting another day can put you months behind. See How to Get It; never wait to order yours.

    Of course get the CF-card version; the XQD-card-version is only for people with an XQD workflow. The only real advantage to XQD is that you can't bend pins — an advantage if you swap cards fast, hard and often.

  • Sony A7s II Sony's full-frame, high-ISO Alpha 7s II can record 4K video in camera itself

    Out of darkness cometh light

    Ultra-high sensitivity up to 409600i with low noise across the whole range
    Wide dynamic range across entire ISO range delivering smooth tonal gradation from dark to bright conditions
    In-camera 5-axis optical image stabilisation for expanded shooting possibilities
    Internal 4K movie recording featuring full pixel readout without pixel binning in full-frame format
    Wide range of professional movie functionality including S-Gamut3.Cine/S-Log3, new Gamma Assist Display, enhanced Zebra Function, Full HD 120fps recording and 4x/5x slow motion recording and full pixel readout without pixel binning in full-frame format
    High-speed AF with enhanced accuracy in wide ranging scenes and advanced shooting functions
    Sony today announced the latest addition to its award winning series of compact, full-frame α7 cameras with the introduction of the α7S II. Offering ultra-high sensitivity and wide dynamic range across the entire ISO range and 5-axis image stabilisation for greater shooting control, the α7S II delivers stunning image quality for photographers who shoot in the most challenging light conditions. Be it the brightest of mornings or darkest of nights, the α7S II enables new levels of photographic expression at whatever shutter speed you wish to deploy. The α7SII also incorporates a host of pro-style movie functions including the ability to shoot 4K video with full pixel readout and no pixel binning in full-frame format, making it an extremely appealing proposition for photographers and videographers alike.
    The α7S II delivers an awe-inspiring sensitivity range of ISO 50-409600[i], thanks to the combination of its 35mm full-frame 12.2 megapixel[ii] image sensor and BIONZ X image processing engine. The sensor optimises the dynamic range across the entire ISO range and broadens the range of tonal gradation in bright environments and minimises noise in dark scenes meaning that it delivers impressive results even in the most extreme conditions. The upgraded image processing algorithm of BIONZ X maximises the sensor’s capabilities and improves depiction throughout the full sensitivity range with particular emphasis on the mid-to-high range. This means that the resulting stills and movies demonstrate extra-fine detail with minimal noise.

    a7s2
    Video Master

    The α7S II can record 4K[iii] movies internally in the XAVC S format[iv] meaning that content is wonderfully detailed. Because information from all pixels is utilised without line skipping or pixel binning, the camera can maximise the expanded power of the full-frame image sensor and produce 4K movies with higher image clarity and negligible moiré. Full pixel readout without pixel binning is also employed when shooting Full HD[v] movies which means that it collects information from approximately five times as many pixels that are required to generate Full HD[vi] and condenses the information to produce extremely high quality movies.

    In a first for the α7 series, the α7S IIcan record 120fps at 100Mbps[vii] with full pixel readout without pixel binning in full frame format which can be edited into wonderful 4x/5x slow motion footage[viii] in Full HD. The α7S II also has the ability to shoot 4x/5x slow motion footage internally which can be immediately reviewed on the camera screen.

    Video functionality has been further enhanced with new profiles; S-Gamut3.Cine/S-Log3 and S-Gamut3/S-Log3. These new profiles deliver wide dynamic range and colour correction is easier to perform. The α7S ll even offers impressive 14-stop latitude in the S-Log3 gamma setting. The camera also supports S-Gamut/S-Log2 which is very popular among cinematographers and videographers. Gamma Display Assist is a new function that allows users to monitor images or check focus when recording S-Log movies and the Zebra function has been improved for even greater control.

    5-Axis Image Stabilisation

    The new α7S II is equipped with the innovative 5-axis image stabilisation system that is proving extremely popular in the α7 II and α7R II cameras. The system corrects camera shake along five axes during shooting, including angular shake (pitch and yaw) which has the greatest impact on image quality and tends to occur with a telephoto lens, shift shake (X and Y axes) which becomes noticeable as magnification increases, and rotational shake (roll) that often affects night shooting or video recording.

    Autofocus accuracy

    The autofocus system on the α7S II has been upgraded and now offers 169 AF points for fast, precise focusing with greater accuracy.[ix] The power of the image sensor means that the absence of noise in images generated, enables the Fast Intelligent AF to detect contrast more easily and react speedily even in low-light situations (as low as EV-4), when it’s even tough to check with the naked eye. When shooting video, the AF performance is twice as fast as the predecessor model.[x]

    Electronic Viewfinder

    The XGA OLED Tru-Finder in the α7S II has been upgraded and offers the world’s highest viewfinder magnification[xi] of 0.78x (roughly 38.5 degrees in diagonal field of view) and shows clear images across the entire display area. The use of ZEISS T* Coating ensures sharp reduction of reflections on the viewfinder and unlike an optical viewfinder, the OLED Tru-Finder can be used to instantly show how exposure compensation, white balance and other selected settings are affecting the displayed image.
