New Sony Alpha A550, A500 target burst, low-light shooters

With the announcements of the Alpha DSLR-A500 and A550, Sony brings what feels like a market microsegmentation strategy to dSLRs. These models raise the total of new Sony dSLRs under US$1,000 up to 5; if you count the older A700, which hasn't been formally discontinued, then you've got 6 Sony dSLR options squeezed into the US$400 gap between US$549 and US$999. A welcome plethora of choices, or a try-anything-and-see-what-sticks strategy? I can't answer that for Sony, but I've been staring at the specs for hours and still can't figure out why the A380, introduced only 3 months ago, exists in this family.

Just announced:

The cameras incorporate Sony's latest technologies for improving low-light shooting experiences. They both use Exmor CMOS sensors (compared to CCDs for the lower-end models), debuting updated on-chip noise reduction which processes chroma and luma channels separately. The quality of its noise suppression has long been one of Sony's weak points, and this can only help. Will it bear scrutiny up to the extended sensitivity of ISO 12,800? I can't wait to test them and see.

They also debut Auto HDR, a variation on the Hand-held Twilight mode, one of the few things I liked in the company's DSC-HX1 megazoom. Auto HDR snaps two sequential shots at different exposures and combines them into a single shot with "optimal" highlight and shadow detail. It doesn't have quite as much control as I'd like--you'll be able to manually select the amount of the bracket, but it's limited to 2 shots and it doesn't save the individual frames, just the combined result and only as a JPEG--but it's potentially a superior approach to the gamma-adjusting schemes such as Sony's Dynamic Range Optimization and Nikon's D-Lighting. Provided there's no performance overhead, of course.

In addition to the resolution differential between the A500 and A550, the A550 has a higher resolution LCD--the same one used on the A700 and A900--and a faster burst option called Speed Priority mode, which basically forgoes continuous autofocus. (With AF, the continuous-shooting performance is the same.)

Notably missing from all these models: Video. At the press briefing, Mark Weir, the senior technology manager of the product management unit in the Digital Imaging Division at Sony Electronics, basically said no one does video up to Sony standards.

"The video implementation of SLRs today do not deliver the video experience people expect from Sony...though we can imagine pros having assistants to pull focus and exposure...we believe that mainstream SLR customers...may not have a camera with the existing technology fill their expectations...delivering an excellent user experience...is an obligation that we have that we don't necessarily see being taken quite so seriously when we see video implementations that don't follow focus...or exposure...we understand that has a value...we can imagine that HD video without focus and exposure...can be tough for people to get a good experience out of...but it has to be better...not just possible, but better."

While I agree that video capture in dSLRs is still rough around the edges at all levels, it's also something that many people miss when they move up from a point-and-shoot, or that they still might want to play around with. Furthermore, I think Sony might have outsmarted itself with its two-sensor Live View autofocus system; since it doesn't use contrast-detection AF I think these models would require a lot more retooling to implement video capture than competitors. Is Sony's exceptionally fast Live View AF worth the tradeoff? Perhaps.

Video aside, however, the A500 and A550 finally look like Sony's aggressively taking on Canon and Nikon in the sub-US$1,000 segment. On specs alone, here's how the A550 stacks up to its competition:

A lot's riding on that low-light performance. While the 50D claims the same ISO 12,800, it doesn't execute terribly well; if Sony nails the noise reduction, combined with the tiltable LCD it could provide quite an advantage. The A550's viewfinder doesn't compare particularly well, though.

The A500 looks a lot stronger in its price cohort. It has the same viewfinder as the A550, but Nikon and Canon's are also small in these models, and their slower burst performance lends Sony the advantage. And even more so in this territory than that of the A550, if the noise reduction delivers as promised, the A500 will be a very strong contender.

One of my biggest complaints about all the low-end Sony dSLRs that have come through here of late are the default settings for Sony's Creative Styles. I really hope they're improved for the new models. I guess we'll find out when they ship in October.

I Think Video Recording Isn`t A Necessary Object For A DSLR Camera.
I`ve 1 DSLR , But Allways Take My Video With My Camcorder.
Even In Time I Thought About Buing A DSLR , Video Recording Wasn`t
One Of My Favorite Specifications.
