Sony a99

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

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

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.
