Sony just announced the 24-70 f/2.8 SSM ($1799.99 USD) and the 70-300 SSM ($800 USD).

I was also hoping that they would be announcing a few more SSM equipped lenses. Like a 14-24 f/2.8 and a 70-200 f/2.8. Maybe Sony will make another announcement in the days to come. This is already their 2nd pre-PMA announcement.

JimC, looks like I just might be picking up an A700. I was (actually I still am) considering a Nikon D300 too. But the A700 does do a few important things better. Like AF faster in bright light (where I do most of my shooting) and in low light. The A700 also writes to high speed CF cards very fast taking advantage of the speed more. And resolves more detail across the ISO range.

Will make my final decision after the PMA show.

Don't forget Dynamic Range (the Sony's ability to capture a wider range of light to dark).

If you look through some of DIWA Labs' newer camera tests using DxO Analyzer, the new Sony DSLR-A700 has better dynamic range compared to any of the cameras they've tested, besting the Canon EOS-40D, Nikon D300, Nikon D3, Olympus E-3, Fujifilm S5 Pro and more.

Here's a chart from it. It's best DR comes in at ISO 200.

To see their test results, click on a camera model, then click on "Test results for camera performance" when you get to choices on the next screen.

Dynamic Range from this new Sony is impressive compared to other cameras.

Of course, you know that I'm biased (since I now shoot with a Sony DSLR-A700). :-)

Phil Askey over a dpreview.com also commented on it in his A700 review conclusion as having Excellent Dynamic range with more highlight range than they are used to seeing.

For example, his tests in the A700 review show it measured at 2/3 stop better than the Nikon D200. IOW, you could retain detail in areas almost twice as bright using the Sony A700 that would be "washed out" with most other DSLR models.

I'm waiting for Dave Etchells' Imatest results, too. I suspect he's probably retesting a lot of stuff since his preview, since Sony has upgraded the firmware to this camera since his initial test shots. He usually measures DR shooting both RAW and JPEG with cameras he reviews. So, I'd keep an eye out for his tests to be finished in the full reviews of newer models over at imaging-resource.com for Imatest test results of Dynamic Range.

Hello JimC,

Thanks for the links. Will check them out in a bit.

Unfortunately the $1750 USD 24-70 won't be available till Spring. So if I get the A700 next month I have to choose from among the currently available non-G series lenses which really aren't of the best quality as many online testers have noted. I could get the 70-200G f/2.8 and shoot with that for a while. Then add the 24-70 to my collection. Followed by a 14-24 SSM (when ever Sony gets around to putting that out...which I assume will be sometime this year...surprised it wasn't announce witht he 24-70...and that a 70-200 CZ wasn't announced...perhaps Sony will announce the 14-24 with the CZ 70-200...shrug).

But as I said the D300 is still high on my list. Though I am now leaning more towards the A700 than I was before.

Btw...do you know when using a SSM equipped lens...will the AF speed equal that of the in-camera motor? Or would it actually be faster or slower (using a DT lens)?

Just buy a Sigma 24-70mm f/2.8 EX DG AF lens instead. B&H has them for $429:

From tests and comments I've seen, this lens is optically superior to the Canon 24-70m f/2.8L, at a fraction of the cost. Browse through the forums posting under the images at the below link, and see some of they comments from someone that has used multiple copies of the Sigma and Canon 24-70mm f/2.8 lenses. Sure, the Canon has better build quality. Personally, I'm more concerned with the image quality ;-)

If you're worried about build quality, buy a spare. ;-)

I would consider it if it had the HSM lens motor. I think I'd buy the "Minolta" 70-200 f/2.8. Then buy the CZ 24-70 in the spring. IF I end up with the A700 over the D300.

Few minutes later...

Noticed that Sigma just announced a few new lenses including a 70-200 f/2.8 HSM. For the Sony and Pentax mounts. Though they do note in green text that "if the camera doesn't work with HSM lenses the AF won't work". Or something to that affect. Hope that doesn't include the A700.

http://www.dpreview.com/news/0801/08...0050150aps.asp

But again to play it safe I'd probably still just go for the Sony (Minolta) 70-200G if I get an A700.

OR. Buy the Sigma 24-70 and have it as a backup after picking up the CZ SSM version. Hmmm....probably not.

Can any one tell me if you will take an AF speed hit using a SSM lens vs using the in-camera AF motor in the A700??

Thanks.
