New Zeiss 16-35mm f/2.8 and 70-400mm f/4-5.6 G Lenses
SAN DIEGO, Sept. 9, 2008 - Sony is expanding its number of high performance Carl Zeiss and G Series lenses with the addition of the new SAL1635ZA and SAL70400G models.
Vario Sonnar T* 16-35mm f/2.8 ZA Carl Zeiss Series Lens
The SAL1635ZA model is a super wide-angle 16-35mm f/2.8 constant aperture zoom lens, well suited for landscape, snapshot, and indoor photography. It is constructed of 17 lens elements in 13 groups, including an extra-low dispersion (ED) for exceptional clarity and center-to-edge resolution and a super ED glass element for much stronger correction of chromatic aberration or discoloration. It also features three aspherical lens elements that provide greater brightness from center to the edge of the image field. Its Carl Zeiss T* (T star) coating technology provides higher light transmission, and minimizes flare to produce images of luminous clarity, color and sharpness.
The SAL1635ZA lens offers the utmost flexibility in challenging lighting conditions due to its wide f/2.8 constant aperture. Combined with Sony's in-camera SteadyShot Inside image stabilization system, this lens is the only large aperture, full-frame capable, wide-angle zoom lens with the benefit of stabilization in the industry. Smooth, fast, and precise focusing is delivered by Sony's Super Sonic wave Motor (SSM) autofocus drive system. It utilizes a solid-state focus drive motor to provide silent, high-speed response, powerful torque, and fine rotational control - critically important for large wide-aperture lenses.
70-400mm f/4-5.6 G Series Lens
The SAL70400G lens is a 5.7x super telephoto zoom lens and the latest addition to Sony's G-series line of premium lenses. Designed to deliver extremely sharp descriptive performance across its wide focal length range, it is ideally suited for sports, action, and wildlife photography. Constructed of 18 elements in 12 groups, it includes two extra-low dispersion glass lenses for high contrast, sharp details, and exceptional center-to-edge resolution with minimal chromatic aberration. A circular aperture with nine diaphragm blades is utilized to achieve natural, aesthetically pleasing de-focusing effects.
With a minimum focus distance of 1.5m and maximum magnification of 0.27x, the lens delivers best-in-class performance. Like the SAL1635ZA lens, focus drive is provided by its SSM system, which offers the speed and rotational precision often required for telephoto shooting. Additionally, the lens has an internal focusing system for faster autofocusing.
A focus-mode/range switch and three focus-hold buttons have been added to the lens barrel for enhanced operability. For both models, when attached to the flagship α900 camera body, the AF hold buttons can be customized to activate the intelligent preview function.
Price and Availability
The Vario-Sonnar T* 16-35mm f/2.8 ZA and 70-400mm f/4-5.6 G lens will ship in January 2009 for about $1,800 and $1,500, respectively.

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.
