<em>New Model Features Ultra-Fast 4D FOCUS, Translucent Mirror Technology and more</em></p>
<p><strong>SAN DIEGO, Dec. 17, 2015</strong> – Sony Electronics, a worldwide leader in digital imaging and the world’s largest image sensor manufacturer, has today introduced the α68 (model ILCA-68) camera with ultra-fast 4D autofocus to the US and Canada markets.</p>
<p>The new camera, which was announced for the European market last month, is the latest model to feature native compatibility with Sony’s extensive collection of A-mount lenses. Inheriting many pro-style features from the acclaimed α77 II, the α68 features Sony’s unique 4D FOCUS system that delivers extraordinary AF performance under any shooting conditions – even in lighting as low as EV-2 where many other cameras struggle.</p>
<p><!--more--></p>
<p>This system utilizes 79 autofocus points – the most AF points on any interchangeable lens camera with a dedicated phase-detection AF sensor<sup>1</sup>. Included are 15 cross points as well as a dedicated F2.8 AF sensor point for dimly-lit scenes. This all adds up to extremely fast, wide area AF with predictive tracking that locks faithfully onto fast-moving subjects. Additionally, the camera utilizes Sony’s unique Translucent Mirror Technology to deliver constant AF tracking at up to 8 fps<sup>2</sup>.</p>
<p>The camera features a 24 MP<sup>3</sup> APS-C Exmor CMOS sensor with a wide ISO 100 – 25,600 sensitivity range<sup>4</sup>, allowing it to produce outstanding image quality for both still images and video. The sensor is teamed with a powerful BIONZ X image processor that uses Detail Reproduction and Diffraction-reducing Technologies plus Area-specific Noise Reduction, resulting in pristine, finely detailed shots every time.</p>
<p>Full HD movies use the efficient XAVC S<sup>5</sup> format, enabling high bit rate recordings at up to 50 Mbps with outstanding detail and low noise. With Translucent Mirror Technology, shooters can enjoy non-stop continuous autofocus with accurate subject tracking during video shooting, producing crisp, professional looking footage. With a powerful array of advanced controls and capabilities, the α68 has plenty to offer experienced amateurs as well as step-up photographers and first time interchangeable lens camera customers.</p>
<p>Framing stills and movies is a pleasure through the clear, bright OLED Tru-Finder, which features 100% frame coverage with high contrast and accurate color reproduction. Complementing the Tru-Finder, the 2.7-type LCD monitor tilts up to 135 degrees upwards or 55 degrees downwards for comfortable composition from a wide variety of shooting angles. Serious photo enthusiasts will also value the backlit top display that allows quick confirmation of camera settings, whether shooting handheld or on a tripod.</p>
<p>As found on the critically acclaimed α7 series, the α68 has a control wheel on the camera’s rear that allows quick fingertip adjustment of camera settings, as well as 10 customizable buttons<sup>6</sup> that frequently-used functions can be assigned to. There is also a front control dial for quick adjustments of settings and a sturdy grip to ensure a balanced shooting experience, even when using heavyweight prime or telephoto lenses.</p>
<p>The new camera features SteadyShot INSIDE stabilization to reduce the effects of camera shake and allow for blur-free handheld shooting at all focal lengths, with any compatible lens. Additionally, the inclusion of a Multi Interface Shoe and Multi Terminal lets users expand their creative options with a wide range of optional accessories, including flashes, lights, microphones and remote commanders.</p>
<p><strong>Pricing and Availability
</strong>The Sony α68 interchangeable lens camera will be available in April at authorized Sony retailers in the US for about $600 body only or about $700 in a kit along with the DT 18-55mm F3.5-5.6 SAM II lens. In Canada, the body and kit will also be available in April and will be sold for about $800 and $950 CAD, respectively.</p>
Tugela said:This is why your camera will often continue to process data long after you have actually taken your shots (a long exposure for example, where data is collected over a period of time and then summed).
dilbert said:The system can only go as fast as the slowest component and right now the slowest component is the CF card.
Hi,Besisika said:I would have bought one if I new. Please let us know next time.ritholtz said:Canon sold it for $110 during blackfriday.
Thanks for the review Dustin, much needed.
Have been thinking about it for a while now.
Yes...it shows a renewed approach to how they do everything, now. The company has definitely restructured itself.9VIII said:Thanks for the clarification. It's nice to see Sigma on the cutting edge of more than just MTF charts.
privatebydesign said:sanj said:Bennymiata said:I use my 16-35 II a lot, and it's been an excellent workhorse.
If the new has BR I'll get the new one, but if not, this lens will last me another 4 or 5 years.
What happens after 5 years? I can last practically forever.... If the new one does not have BR (I think it will) then the next replacement will be LONG time from now.
The lens will probably still work, though after enough time Canon don't support it and the inability to get parts for them will make many of them paperweights. I think the more relevant point is the IQ doesn't really stack up for many images.
The 16-35 f2.8 MkII came out when the Canon wide angle lens design team consisted of a on old blind guy, the work experience guy that also empties the bins when everybody went home, and the new kid who didn't know what end of the lens went on the camera. Well that new kid made good, he went to optics school in the evening and continued on to write his PHD on an unimaginable concept, a 17 TS-E. Well the old blind guy signed off on the 17 idea even though he truthfully didn't have the authority to and the blind guys protege, the 'new kid', became the wide and ultra wide go to guy. The marketing department, fresh from the success of the 17 TS-E put pressure on everybody else to let 'the new guy' do whatever he wants, kind of a Japanese lens skunkworks. Because all these random elements (little pun intended) fell into place, we now have the 17 TS-E, the 24 TS-E MkII, the 8-15, the 16-35 f4, the 11-24, the 35 f2 IS, the 35 f1.4L MkII.
The 16-35 f2.8 MkII is a weak performer by modern standards, and while content might trump IQ a lot of the time, there is a limit and those old weak Canon wides are not a thing of beauty.
I have a Zacuto, which works, but I prefer the S-type focusing screen.Jopa said:johnnycash said:Eldar said:I have a custom made precision focusing screen in my 5DSR (I got one for the 1DX also, but have not used it since I got the 5DSR) and manual focus is a lot easier than many seem to believe, even in poor light. If you shoot wide open, your subjects better be fairly static though.
In addition to my 12 AF lenses, I have 8 manual focus lenses (6 Zeiss and 2 Canon TS-E). I love using them and I routinely shoot them wide open. People seem to believe that AF is preferable in every situation. But that is not true in every case, at least not for me. When you want to focus on a small detail behind large front objects, that is a lot easier and faster with manual focus. When you want something in the periphery of the image in focus, outside the AF point matrix, you can focus directly and skip focus/recompose. When your AF point is in the top right and your subject is to bottom left, you can skip moving the AF point etc. etc.
In my case, without having a good explanation for it, I am a better photographer with primes than with zooms and I am even better (or less bad) with manual focus. I believe it has to do with the attention and focus it requires. I would never use them for a low light event though.
Hi, you have a custom made precision focusing screen in your 5DSR? Can you please tell me more about it? I love using my Otus, if only I could use the viewfinder!
What about a live view magnifier like Zacuto? It's no worse than an EVF.

Canon Rumors said:We have been sent a specifications list for the upcoming Canon EOS-1D X Mark II. This one is more in line with what we’ve been getting in pieces over the last 6 weeks or so.</p>
<p>Specifications:</p>
<ul>
<li>24mp full frame Canon sensor</li>
<li>80+ AF Points</li>
<li>New processor technology</li>
<li>14+ stops of dynamic range</li>
<li>Nearly 15fps</li>
<li>4K video (max frame rate unknown)</li>
<li>Dual CFast</li>
<li>Slightly larger LCD</li>
</ul>
<p>It’s possible there is marketing material being made for the upcoming camera, and we may start seeing some of those leaks.</p>
<p>More to come…</p>
9VIII said:If the amount of surface area occupied by circuitry is the same per pixel, just for a harsh estimate lets say 10 square microns, then the A7S would be losing approximately 14% surface area per pixel... But the A7RII would lose 50%.
Using an expensive fabrication method to get back 14% of your sensor's potential doesn't sound that appealing.
