TBH I'm probably in the danger area anyway, and I suspect that with the high pixel density on the A900 the anti-shake is always going to be less than effective, purely as there are more pixels to record the blur.
Trouble is - in good light, its not needed, and in borderline light, it really doesn't seem to do very much! Maybe its more effective with longer lenses.
Without wanting to start an inbody vs in-lens IS / VR debate.. too be honest from what I am seeing a Nikon 18-55 VR kit lens is far more effective than Sony's SSS though if I can be honest here!
I would agree with you on the in-body vs in-lens, think the in-lens is more effective especially when you start making the sensor bigger. It does do the job and there are advantages of having it with every lens (such as primes), but really the solution is to have both.
I'm pretty sure the a700 was better on this front, maybe it was because the sensor was smaller (so easier/quicker to move). Like all things at this time in my life, I owned the a700, I sold it to switch to the a900 about 6 months ago, and can't for the life of me really remember to compare the two cameras.
So both would be nice.. 'In body' to give you that little bit extra with every lens, and 'in the lens' for a specialist application, like a long zoom, etc. I did read somewhere that Sigma were looking at this lens based OS on Sony and Pentax mounts, which have in-body. I wonder whether having both will be here sooner than we think!
2008 was the year for LV. 2009 looks like it's the year for HD video. Maybe 2010 is the year for hybrid OS/IS/VR/SS/SSS.
Also, it's SS on the A900, NOT SSS (Super Steady Shot). Not sure why they dropped the 'Super'
BTW, I upgraded my version of DXO last night (as Elite is needed for a900) after your comments about Capture One being better than ACR, but got a bit of a green surprise (or should I say green tint!). Wondering what I was doing wrong, I gave up and went to bed. Checked DXO's forums this morning and guess what? Looks like I'm not the only one! It's a known bug which is being worked on, but I wish I knew that before I handed over my cash. But I guess, the lens correction modules seem to have much better support nowadays for the new Sony range - pretty much every G and CZ is now covered.
Shadow noise also looks like better/smoother, at errr, those ISO's you'd not expect shadow noise. (Sssshhh)! Is is me, or does Adobe seem to turn the Sony noise pattern into grains of rice? [do Nikon files have that same rice grain texture?)
Anyway back to DXO, apart from the green tone that is rather annoying, I'm kind of liking it, and also like their attempt at intergration into Lightroom (you can see the Lightroom library from within DXO, so you can select the RAWs, edit and convert, and push back to LR in with Jpg, TIFF, or DNG (converted RAW)
