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.

what conditions did the a700 survive in that the 1Ds didn't?hanugro - Friday, September 12, 2008 - link
Hm ,I do remember last year that I heard about shooting video and choosing 1 fram as digital still from SOny CEO himself. I don't know whether it is his idea or he heard from someone else. But Sony has stated that it won't put feature that is not ready. I am sure it has cross Sony's mind. Also they are one that among the first develop sensor that can take 120fps but at lower resolution. You have to understand that this 24MP create about 15MB per frame. If your video is 24fps then does the CF available now is big enough? Also don't tell me that SOny should allow lower HDTV 1920x1080 pixel video and hope that you can extract one frame of it and sell it to newspaper. They will laugh at it, newspaper / magazine needs at least 6-12MP pictures before they consider to publish it. Also if you want video then buy videocam instead. I imagine using liveview (or using the sensor for video) will shorten the live of the sensor itself. Whay would I want to do that?aeternitas - Friday, September 12, 2008 - link
I think people willing to pay 3k for a camera;#1 Dont care about 100$ battery. (wtf?)
#2 Could get something better for a bit more if they want new.
#3 Something better for less if they buy used.
#4 Nikon and Cannon will come out with something better for less in a matter of a few months.
"Full frame" is great, but all it does is get rid of crop factoron 35mm cameras. What happeneds when CCDs get bigger? They will need to, becuse no matter what technology the camera has in it, SnR is going to be better at lower MP resolutions on the same size CCD. 24MP sounds fantastic, but noice reduction does not always equate to added detail. The only real way to get more detail, is to actualy replace noise with information and the real only wat to do that is to make the CCD bigger or make the pixelsites bigger.

Nice preview of a very interesting camera. I did notice several times you mentioned the Sony as being twice the resolution as the D3/5D which is not accurate. It has twice the pixels but you need 4x the pixels to truly double a sensors resolving power.This camera should shake up the industry on the high end. I can't see Canikon shooters ditching their current investments and going with Sony because of this cam, but at the very least the era of high resolution FF cameras costing as much as a new compact car is over. Bravo Sony.

Just a note: Canon's 1Ds mkIII has a larger viewfinder than the A900 in specs...Canon 1Ds mkIII: .76x 100% FF vf
Sony A900: .74x 100% FF vf
Yea the Canon costs more than 2x as much. However, if history has its say, Canon will trickle down the viewfinder like it did from the Canon 1Ds mkII to the 5D (0.70x in the 1Ds mkII and 0.71x in the 5D). Whatever Canon has up its sleeve, its likely a full frame, and hopefully Canon users will get a nice large viewfinder in whatever the followup to the 5D is.

As for the bump in fps rate with cropped lenses like Nikon does, apparently this is due to a lens design decision by Minolta. The aperture arm must travel a much more significant distance compared to the aperture arms in Nikon's lenses. This physical requirement alone is likely what is limiting all of Sony's DSLRs to 5fps maximum.Wesley Fink - Friday, September 12, 2008 - link
I shot several images with DT lenses and the A900 crop factor worked perfectly. You can also manually force DT, even on a full-frame lens. With that capability, and an 11 megapixel image size in crop mode, a faster shooting speed would have been an incredible feature. The Nikon 5 megapixel crop-mode image is OK for newspaper but too small for some things. An 11 megapixel crop is a lot more interesting.strikeback03 - Friday, September 12, 2008 - link
The point of an L bracket is to get the flash above the lens regardless of camera orientation. This new flash still has the flash offset to the side, so you still need a bracket if you want to move your flash over top of your lens.Wesley Fink - Friday, September 12, 2008 - link
There are some cases where an in-line flash is more desirable, but for most situations where photographers use a flash the Sony 90 degree turn will accomplish just what the photographer is looking for when he attaches an L bracket.haplo602 - Friday, September 12, 2008 - link
I bought a Nikon F75 as my first SLR after some long search and decision making. Then a few days after it's arrival I learned about the Minolta Dynx 7 and regreted my decision. A few months later I had the opportunity to actualy shoot with a Minolta 7D and I was even more unhappy.Now with this new Sony, I am close to tears. The Nikons I have are solid cameras, I do not complain there, however any Nikon camera close to this Alpha sensor will cost a fortune which I cannot afford. The A900 seems like a quality and "cheap" camera.
(I have to add I never owned a DSLR :-))
