Default Sony's best kept secret !

That is a very impressive image, NHL-

I am assuming that the lens used is the SAL-500F80 lens. How is the auto focus quickness with that reflex design lens?

Thanks for posting. Have a great day.

So, is a congrats in order (i.e., did you buy an A900 or were you borrowing one to try it)?

Surprisingly quick!

Even in dark indoor this camera has no problem focusing @ f/8, but being a full-frame the viewfinder is so bright that you can't even tell the difference between it and my cropped D300/Bigma combo when looking through the camera

Thank you - I bought it with the CZ 24-70 for my upcoming trips overseas

Cool. That should be a very sweet combo (with the CZ 24-70mm outperforming the latest Sigma, Nikkor and Canon 24-70mm f/2.8 lenses from tests I've seen).

So, Congrats!

The new Sigma 24-70 was a difficult decision with the Sony's rebate on their camera/lens combo...

I will get the Sigma 50m f/1.4 EX though

The Sigma 24-70mm f/2.8 HSM should come pretty close in optical performance, and it's significantly better than the Canon 24-70mm f/2.8L from tests I've seen. Only the Nikkor and CZ 24-70mm f/2.8 lenses test better (with the CZ coming out on top). But, I suspect the Sigma or CZ would be great choices in Alpha Mount.

If budget is not a huge consideration, then the CZ is the obvious choice (and I can imagine the extra $300 discount swayed you a bit). lol

Yes, the 50mm f/1.4 EX HSM seems to be the 50mm to beat right this minute.

If you haven't seen it, here's a review with tests comparing the Sony/Carl Zeiss, Canon, Nikkor and Sigma (newest HSM version) 24-70mm f/2.8 lenses in various areas:

http://www.lenstip.com/index.php?tes...wu&test_ob=172

P.S.

Note the comments on the page testing resolution. The CZ is the one to beat when used with the aperture wide open. For example, see these comments (note the "class of it's it's own" part):

"Perhaps it’s not a fault but it’s worth notice that the Sigma is slightly worse than the Nikkor and the Zeiss. The second lens is a class of its own because the results of over 40 lpmm were optained even at maximum aperture."

http://www.lenstip.com/172.4-Lens_re...esolution.html

It goes on to discuss how the Sigma is better compared to the Canon 24-70mm f/2.8L.

The review also has some measurements between the Sigma and Nikkor 24-70mm f/2.8 lenses on a D3x to show full frame performance, and the performance of the Sigma on the Sony A900 should be about the same as that lens on a D3x, other than differences in image processing that probably wouldn't influence most lens tests much (since both cameras are using a Sony 24MP sensor).

Yes - IMO anyone buying this camera has already thought out their lenses options...

For example I'm quite amused at Canon latest Macro release in response to the Nikkor 105VR when any old macro mounted on the Sony will automatically get stabilized!
-> Another thought about this 500mm is that I can stay pretty far away and get the shot whereas with a shorter lens theses Monarch would have fly off before I can get close for the shot.
