Hands On: Sony Alpha A77 and A65 Translucent Mirror DSLR, Plus DT 16-50mm F2.8 SSM Zoom Lens

The translucent mirror technology has been working out well for Sony and now they've gone and stuffed it into two new DSLRs, this time aimed at higher-level users. Here's the breakdowns of the two new models.

SLT-A77

The direct successor to Sony's mid-level A700 uses Sony's newly-developed 24.3-megapixel Exmor APS HD CMOS sensor and the latest version of Sony's BIONZ image processing tech.

Thanks to the translucent mirror (like the one found in Sony's A33, A35 and A55 DSLRs), Sony claims the A77 to have the world's fastest continuous AF among DSLRs. It can pull down 12 FPS at full-resolution while keeping up phase-detection AF. Even the sound of that is pretty impressive.

The AF system is rounded out by 19 AF points with 11 cross-type sensors. The shutter has a minimum release time lag of just 50 milliseconds, which hammers home the idea that Sony was really going for pure speed with this thing.

The unique viewfinder system has been improved with a new OLED Tru-Finder viewfinder, which uses a 2359 dot display to give you 100-percent coverage of the frame through the eyepiece. That allows you to zoom in on the image to check focus and even preview exposure changes in real time.

Another cool feature is the built in Smart Teleconverter mode, which allows you to drop the image resolution to 12 megapixels in exchange for a crop factor of 1.4x or 2x.

Switching over to video mode, Sony is proud to proclaim themselves the first company to achieve 60 FPS at full HD resolution using the new AVCHD Progressive format. That's a result of the upgraded BIONZ processor's ability to churn through more data in a quick way. It can also still do more traditional 24p shooting, while offering a full suite of manual control modes.

ISO settings range from 50 all the way up to an expanded setting equivalent to 16000. It has on-board GPS for geotagging, and a shutter that's rated to 150,000 actuations. Plus, the 3-inch, 921K dot, Xtra Fine LCD display tilts and pivots in three directions for maximizing wacky shooting angles.

But how much are all of those bells and whistles going to cost? The kit, which comes with the newly-announced 16-50mm F/2.8 zoom lens (more on that here) will ship for about $2,000. If you only want the body, it'll cost $1,400. That makes it cheaper than Canon's 7D, about the same as Pentax's K-5 and about $200 more expensive than Nikon's consumer-level D7000. On paper, it outmatches all three in quite a few areas and occupies a space that may be advantageous for Sony.

SLT-A65

As you might expect, the A77's little brother shares many of the same familial traits. It uses the same combo of a 24.3-megapixel Exmor APS HD CMOS sensor and BIONZ processor. It also carries over the OLED Tru-Finder, the high-end video capabilities and, of course, the translucent mirror.

There are some things missing in order to make up for its cheaper $900 price tag. Instead of 19 AF points, the A65 has 15 total with just three cross-type sensors. It also gets 10 FPS with full-time phase detection AF while the A77 gets 12. The lowest ISO setting is 100, compared to the A77's 50 and its 921k dot LCD screen only rotates in two directions instead of three.

DT 16-50mm F2.8 SSM

As a complement to their new bodies, Sony has rolled out an extremely versatile standard zoom with a range that should sound vaguely familiar to many crop-sensor shooters. The body is dust and moisture resistant and it uses three Extra Low Dispersion lens elements to cut down on ugliness at all focal lengths. It has an internal Super Sonic wave Motor for quiet focusing and at $700, is very affordable if you consider what you're getting.

VG-C77AM Vertical Grip for A77

As you can see in the pictures, Sony has also introduced a new vertical grip meant to work with the A77. It mimics the controls offered by holding the camera in the traditional way and is beefy like the grip for the A900. It hold two batteries, which Sony says will stretch the time between charges to about 1,000 shots. It checks in at at a price of $300, which makes it the most expensive non-wireless DSLR grips we know of.

Sony's New Fast-Firing DSLRs and NEX-7

Sony announced a pair of new DSLRs in their Alpha line today, named the A77 and A65. As our sister publication Pop Photo awarded Sony's A55 the camera of the year award in 2010, we sit up and take notice whenever Sony releases a new flagship DSLR--and we're glad we did this time, because good lord, these are some impressive cameras.
Both are outfitted with the newest version of Sony's Translucent Mirror tech, basically an entirely new type of camera that our counterparts at Pop Photo absolutely love. You can read a longer description of that tech and why it's amazing here, but essentially the idea is that by using a translucent reflex mirror (rather than one that must be flipped up and away when switching to video mode), Sony's cameras enable legitimate autofocus for video. The higher-end A77 boasts the newest version of the Translucent Mirror, which gives it the world's fastest continuous autofocus shooting, capturing full-rez images (and at 24-megapixels, these are massive ones) at 12 frames per second (the A65 gets 10fps).
The viewfinder, another major strength of Sony's latest Alpha cameras, also gets an upgrade--this time to a high-resolution OLED. Instead of using an optical viewfinder, these digital ones allow all kinds of tweaking and overlays of settings, so you don't have to withdraw your eye and mess around on the camera's LCD to quickly change your aperture or white balance.
A surprising amount of the tech in the Alphas gets carried over to Sony's new interchangeable-lens compact, the NEX-7, the predecessor of which we ranked one of the best cameras of last year. It's got the same 24.3-megapixel sensor and same processor as the big boys, for example. Read more about it here.
You can read more about the NEX-7, A77, and A65 over at Pop Photo--and see a gallery of images taken with them, as those lucky photogs have been playing around with these cameras for a good few days now. The A77 will retail for $1,400, and the A65 for $900, with just the body--no lenses included. The NEX-7 will run for $600, body-only.
