Flagship HVL-F58AM Flash
SAN DIEGO - Sony is expanding its α (alpha) system of accessories to include the new HVL-F58AM flash unit with exceptional features for versatile and flexible external lighting control.
Quick Shift Bounce and Expanded Versatility
This new flash features a new and innovative Quick Shift Bounce system. It offers more creative ways to achieve lighting, flash and bounce angles you may not have been able to experience before. The flash head can pivot 90 degrees left and right on a horizontal axis in addition to the conventional up and down vertical adjustment. With this system, the camera and flash unit can keep the same orientation regardless of portrait or landscape shooting. This gives a higher degree of flexibility when arranging the direction of light. For example, you can take full advantage of the flash unit's built-in bounce card even during portrait shots since the flash head can maintain the same orientation as it would in the landscape position.
Enhanced Operability and Ease-of-Use
A powerful performer, the HVL-F58AM flash unit features a maximum guide number of 58 at 105mm and ISO 100. It recycles (or recharges) in as little as five seconds, approximately 55% faster than the predecessor HVL-F56AM model, so you are ready to capture the next shot. And because it features a quiet recycle charge, there's no whine to distract you from your subject. It also has a large, easy-to-read LCD screen that is about 13% larger than its predecessor's. Its intuitive control layout makes it easy to control flash functions and configure the settings based on your shooting needs.
Wireless Auto Flash Control
This new flash has wireless auto flash control so you can remove the flash unit from the camera and easily light subjects from different angles. Photographers can create soft shadows to add depth to their images and avoid the strong shadows and hot spots that can occur with front lighting. The HVL-F58AM flash unit can also control the ratio of lighting from several off-camera flash units.
Up to three groups of flashes can be set up for optimal, complete control of lighting via a wireless connection. Flash output ratios can be adjusted automatically without having to do tedious exposure calculations. Additionally, you can fire a modeling flash to preview flash effects before taking the picture. Even with multiple units, the modeling flash fires according to the flash ratio you have set.
Advanced Features for Optimal DSLR Performance
One of the flash's most advanced features is its sophisticated zoom control that automatically optimizes illumination angles that are suitable for either APS-C size or 35mm full-frame sensors. This control reduces light "fall-off" at the periphery of images. It also has an advanced white balance compensation system that gathers color temperature information, complimenting the white balance information reading of the camera. This achieves more accurate results when the main unit is in auto white balance mode. Other features include: high-speed synchronization at shutter speeds of up to 1/4000 of a second, ADI flash metering, manual flash and zoom (six levels), multiple-flash, and a supplied mini-stand for greater wireless freedom.
Price and Availability
The HVL-F58AM flash unit will ship in September for about $500 at sonystyle.com, Sony Style retail stores, military base exchanges, and authorized dealers nationwide.

If I had any personal gripes with Sony,it would be because of their 'business tactics' in the past with things mentioned by Westley here. Westley made mention of the 'battery issue', but what he did not mention was Sony's bad judgment in the past concerning rootkits.Sure, Sony's motivation for installing 'software' on a system without the users knowledge may have had to do with protecting their IP(DRM), but I have to question any company who deems they have the right to take control of any system that does not belong to them. Also, for those who may think that this is no big deal, keep in mind that even USB thumb drives, etc have their own MAC address.
What does this mean to the end user you may ask ? This means that anyone of us *could* potentially be locked out of the hardware that we payed hard earned cash for at the whim of a company who obviously has serious moral issues.
Thankfully Mark Russinovich caught this back in 2005, but it took several class action suits, and a court order that made Sony pay up $150 to each affected individual before they stopped shipping the CDs(almost two years later).
Now onto the subject of lenses. Zeiss also makes Nikon glass, but according to Ken Rockwell (heh yeah I know . . .) Zeiss actually does not make these lenses(some other company in Japan does), and most of, or all of these are MF. Ken Rockwell then goes on to say - "When photographers want quality they use larger format cameras, not 35 mm. " Nothing he says here really matters to me. All I care about is how well any given lens I purchase performs. I suppose the part he mentions going to a different format for quality does sort of make sense, but since I am not a 'professional photographer', my Nikon DSLR will just have to do . . . The thing is though, Zeiss is not the end all be all of lenses, and other manufactures make good lenses as well (Nikon for one).
I did the research more than 1.5 years ago when purchasing my first DSLR, and at that time, there just was not a broad enough lens selection available for the Alpha 100. Obviously I decided against it(and I do have my reasons), but with shooting pictures with a decent DSLR, I am finding that knowing how to use a camera in the first place makes more of a difference than the 'quality' of equipment used.
In the meantime, while the latest Alpha may have some desirable features, and can use some seemingly nice glass. I think I would have to pass on the 'latest flavor' of the month. Also seems to be yet another company who can not get it into their heads that the 'big MP penis' *thing* was a last year and before trend. While this year savvy photographers have been asking for, and want more dynamic range . . .

Yes. Right now, most of Sony's lenses are old, and not intended for digital sensors. There are a few Zeiss lenses, which are certainly good, though not quite up to the standard of their third party offerings for Nikon, and now Canon. But their Sony models do auto focussing, which the Nikon and Canon models do not.It's surprising that their sony models, at the prices that they sell for are not weather sealed as Canon and Nikon's own lenses are.

1. Sony have made it very clear all through the A900 development that they do not consider the A900 a Pro body (albeit capable of being used by a Pro).I guess a proper Pro body (or several) comes later if they decide that they really want to seriously target that market.
2. the reason that there is no increase in burst speed in APS-C mode is that Minolta/KM & now Sony have never had a shutter/mirror mechanism that can do more than 5fps i.e. it's the shutter that is the limiting factor not the image processing abilities.
3. batteries - yes, it's dear compared to generics but it's no dearer than equivalent Canon, Nikon, Olympus, Pentax genuine batteries.
& I've got to say that it's a great battery in terms of performance so I don't need as many.

Sony is an Industry standard in broadcasting with their video cameras, expect it to become a reference standard in photography as time passes. They have the engineering power to solve problems, and almost an unlimited budget to make things happen. They are the freshman in the SLR market and already making good decisions, it's only a matter of time before they get all of it right. The other question to factor in is how the photo industry will accept Sony as a future industry standard. Artist and photographers tend to stick with what they know and love. Lets see how their incredible marketing team handles that. It might be Sony take over, PS3 stile.Only time will tell.

Looks interresting, but there are a few things that stops me from buying right now. First, it's the first of its kind in a new breed from Sony. Some functions and engineering is just great, while some other seems premature or even absent. Onther big backlash is the batteries. I don't wanna end up with a "Sony-only" choice of battery source. I have have a friend that is tied to the Sony batt-packs, and he claims it is really a pain in the ass.For now on, I'll probably wait until Nikon or Canon turns up with a similar 24 MP unit, just because of what I mentioned.

Actually, the entire range of Konica-Minolta engineers are in Sony's employ and you cannot get any more expertise than that, from a photography perspective, regardless of manufacturer. As far as electronics and sensor technology is concerned, Sony has been doing that for a while, including as a supplier to Nikon.Bottomline, in the "DSLR", the "D" aspect is covered through Sony's own expertise/know-how and the "SLR" aspect is covered through the prior Konica-Minolta engineers.
I would not have too much concern about Sony being new to this field.
They did have some mis-steps when the A700 was initially released one year back, by applying NR onto RAW (BAD in my book) but they have completely reversed course, with the upcoming release on Sept.16th, of Firmware Ver.4, which completely changes things for the better.
Now the RAW files are virgin-untampered-RAW-files (with the NR-OFF setting) and is unbelievably detailed even at ISO 6400 and seemingly has even more luminance data in it than its peer, the Nikon D300 (which shares roughly the same sensor).

how much is sony paying you ;)i'm going to wait for some side by side comparisons by phil askey, etc before putting my money into something that isn't even on the market yet.

I suppose if you have already decided to buy Canon or Nikon then waiting for Phil's side-by-side makes sense. You can always be sure Canon or Nikon will be the winner in Phil's reviews. And dpreview and their parent Amazon are obviously paying me nothing.chiew - Sunday, September 14, 2008 - link
are you saying you are more qualified to compare cameras side by side than phil or any other site's reviewers? dpreview was just one site i mentionedKorruptioN - Monday, September 15, 2008 - link
It has been generally seen that Phil favours his Nikons and Canons over something "different", such as a Sony. Cameras that are technically stronger but are of the "different" nameplate earn lower final ratings than a camera from one of the proven stablemates.
