This maybe the next big hitter in the Mirrorless movement ? We will have to wait and see.

A7mkII

Sony has announced the Alpha 7 II, which the company has managed to keep very close to its vest. The big story on this 24MP full-frame mirrorless is its 5-axis sensor-shift image stabilization – the first of its kind in a full-frame mirrorless camera. Sony claims that this IS system can reduce shake by 4.5 stops using the CIPA standard. If an E-mount lens with OSS is attached, the camera will detect it and use a combination of in-lens and in-body stabilization.

Like the original a7, the a7 II features 117 phase detect and 25 contrast detect points on its CMOS sensor but Sony is claiming a 30% improvement in the a7 II’s AF speed and 1.5x better tracking performance than its predecessor. Sony says this is thanks to its ‘proprietary image analysis technology’ using more information from a scene to keep focus locked on a subject.

On the video front, the Alpha 7 II now supports the XAVC S codec, which can record 1080/60p video at 50Mbps. The camera also supports S-Log2 to capture a wide dynamic range in video for grading.

From a design standpoint, the biggest changes are the grip – which is larger – and the addition of a front dial. The shutter release button has been moved to a more natural position on the grip and the front panel is now magnesium alloy instead of plastic. The lens mount has also been reinforced, for more stability when using heavy lenses.

NEX

Intro-001Lately I’ve been using a camera in the Sony lineup called the NEX-5R and have really been enjoying it much more than I thought I would and have reached a point that alot of other photographers have. I reach for the camera that works the best for me. Needless to say its the one that I purchased as a backup to my big camera, the Sony a77 that weighs about 10 times as much. My new camera of choice the NEX-5R.

The great thing about the system is the adapter you can get for it. Any camera you are using now or in the past, even in the film days, you can find an adapter for it. Its Amazing, and with the focus peaking option even manual focus is easy.

The Alpha NEX-5R is Sony’s seventh NEX camera and the third in its ‘5’ series that aims to appeal to a more demanding customer than the point-and-shoot-upgrader-friendly ‘3’ cameras. The 5R is a subtle upgrade over the existing 5N but the changes wrought suggests Sony has a clearer idea of who each camera is ment for.

The NEX-5R isn’t a NEX-7 by any means, but it’s finally added a couple of features that make it more attractive to keen photographers – namely a dedicated function button and control dial. These may essentially be an extension of the level of control that the 5N already offered, but devoting more space to external controls shows that Sony expects the users to actually use these functions.

The biggest technology advance on the NEX-5R is the addition of a modified sensor with pixels devoted to performing phase-detection to provide a hybrid autofocus system. The phase-detection pixels are used to determine depth information about the focus target, which means the camera has to perform less hunting with the potential of faster focus, improved continuous focus performance and better autofocus in movie shooting.

The other big advance on the 5R is the addition of DNLA-compliant Wi-Fi and on-camera app, the NEX can only run Sony-made apps, but the couple included on the camera do increase its capabilities. The Wi-Fi and apps combine to mean that the 5R can push images to an iOS or Android smartphone, push images straight to Facebook or Sony’s own PlayMemories site across a Wi-Fi network, or allow the use of a smartphone as a remote viewfinder/trigger.

  • 16.1MP CMOS sensor w/10fps
  • ISO 100-25600
  • Top-plate control dial
  • Dedicated Fn button
  • Wi-Fi for connection via Wi-Fi networks or to smartphones
  • Proprietary in-camera apps
  • Touch-screen display
  • Electronic First Curtain shutter
  • 1080p 60p HD movies in AVCHD (50p on PAL region models)

Sony a99

Posted in DSLR, sony alpha, Uncategorized with tags , , , , , , on December 27, 2012 by reselgroth

TS300x300The Sony SLT-A99 is the Japanese camera maker’s flagship model, aimed squarely at DSLR enthusiasts who will settle for nothing less than a full frame sensor in a rugged body with a plethora of external and customizable controls. It arrives almost four years after its predecessor, the A900, the company’s first full frame DSLR. You’d certainly expect significant new features given such a long gap between products and Sony has lost no opportunity to equip the A99 with every bit of electronic expertise they’ve incorporated into their NEX and SLT models in the interim. Whereas the A900 was a defiantly conventional SLR that would have been immediately familiar to Konica Minolta film-camera users, the A99 is something of a technological tour-de-force.

Start with a dual chip AF system, live view focus peaking, tiltable rear LCD, built-in GPS and 1080p60 movie recording plus the ability to output uncompressed video, and the contrast to the stills-only A900 couldn’t be more stark aside from the A99’s identical 24MP resolution. And then of course, there’s the fact that with the A99 Sony has opted for an electronic, versus optical viewfinder. From a features standpoint, it’s clear that Sony was out to rethink its approach to the enthusiast market and attempt to lure would-be DSLR shooters with a surfeit of technology while broadening its appeal to videographers.

Like its predecessor, the SLT-A99 enters a full frame DSLR playing field still dominated by the ‘big two’, so the camera’s success will depend not just on its advances over the A900, but how well it competes against the Canon EOS 5D Mark III and Nikon D800. Sony may have chosen not to challenge the 36MP Nikon D800 for pixel count – somewhat of a surprise given that the D800 houses a Sony-made sensor – but has opted instead for a unique dual sensor AF system that promises more precise subject tracking along with a 6fps continuous AF burst rate.

Sony has gone to great lengths to stress the work that has gone into improving the camera’s image quality. The latest 24MP sensor has been designed so that more of each photosite is light-sensitive. The electronics in front of this light sensitive region have been slimmed-down to increase the angle from which each site can receive light. These changes, combined with a design that provides a short and high-capacity path between the sensor output and the image processor, and the addition of 14-bit Raw output, should mean improved still image quality.

The rapid adoption of DSLRs by video professionals has made HD recording with manual exposure control a stock feature in even mid-range models. With the A99 though, Sony leverages its considerable video expertise by combining 1080p60 video capture with SLT-enabled phase-detection AF along with the ability to output uncompressed video over HDMI (a feature we first saw in the Nikon D800). Another well-implemented nod to the needs of run-and-gun videographers can be found in the inclusion of a ‘silent controller’ that allows for adjustments to made while recording without the attendant button clicks

a77 Firmware 1.06

Posted in DSLR, sony alpha with tags , , , , , , , , , on October 23, 2012 by reselgroth

The Alpha 77 upgrade also adds in-camera lens correction support for the SAM 30mm f/2.8 Macro, SAL 50mm f/1.4 (and presumably for the Minolta/KM equivalent with the same lens identity), the SAL CZ 24-70mm f/2.8 SSM, SAM 28-75mm f/2.8, SAL 70-400mm f/4-5.6 G SSM, SAL 70-200mm f/2.8 G SSM, SAL CZ 16-35mm f/2.8 and SAL 35mm f/1.4 G (again, presumably also correcting the Minolta/KM lens with the same identity number).

There are initial reports of a faster response, and faster image review time, supported by other Sony sources (Sony UK does not list these). Changes like this are normally accompanied by minor improvements in image quality, as the firmware has to be addressed pretty deeply rather than just tweaking a few parameters. Nothing gets to work faster unless it’s re-coded and that is good news. This is a near 64-megabyte program download, and not all of that is used for the updater part of it which runs on your Windows or Mac machine (exact specs are given on the links, and 64-bit is not supported so you need an old laptop or something like that to do your updating, if you have current systems – we always keep an older machine around for exactly this reason).

Specific additional claims which have surfaced include faster start-up and/or shutdown, more responsive front and rear wheels (?), improved auto review response, better AF performance with the new 500mm G, and better AF with scenes including bright areas. http://www.sony.co.uk/support/en/product/SLT-A77/downloads/FW_A77_V106_WIN

Sony A77

Posted in Uncategorized with tags , , , , , , , , , on June 1, 2011 by reselgroth

The A77 announcing in July.  If Sony’s new A77 SLT does indeed have a 24mp sensor,  it should be as good or better than Sony’s lovely 16mp sensor. It would have better corner to corner resolution than the A900 and A850 because it will be taking advantage of the sweet spot of the same full frame lenses they use, and a serious advantage even with lower priced lenses over higher priced lenses FF require just to get close to the kind of corner to corner sharpness levels APS-C can produce. We’ll see what happens in July ? (7/11/11) Latest update says it’s NOT going to be a SLT but will be a SLR.

Sony is expanding its line-up of over 30 A-mount lens.

Sony is expanding its line-up of over 30 A-mount lenses with new models that will appeal to seasoned photographers and those new to DSLR cameras alike – a 35mm f/1.8 DT (APS-C) SAM, an 85mm f/2.8 full frame SAM, and the long-awaited 24mm f/2 Carl Zeiss Distagon T* 24mm f/2 for full frame with SSM ultrasonic focusing.
The Distagon T* 24mm F2 ZA SSM (SAL24F20Z) features Carl Zeiss Distagon design and rounds out the existing Planar (SAL85F14Z) and Sonnar (SAL135F18Z) models also developed in conjunction with Carl Zeiss. It is intended to appeal to experienced photographers looking for a large-aperture wide-angle lens of real distinction.

The DT 35mm F1.8 SAM (SAL35F18) adds the important 35mm focal length to what Sony now calls the ‘Easy Choice’ series. ‘Easy Choice’ is intended to provide great value, compact and lightweight lenses that are attractive to entry-level and advanced photographers alike. Each lens in the series is selected for a specific purpose, for example portraiture or macro. – Sony definition.

The 85mm F2.8 SAM (SAL85F28) is another ‘Easy Choice’ lens, this time offering the 85mm focal length considered the standard for portraiture because of the natural perspective it provides. True to type it is extremely compact and light, weighing just 175g.
