HI ArneHi Jono, thank you for sharing your impressions of the a900, the info re the weak AA filter is interesting and would indicate excellent resolving power+more realistic looking images out of the box (so to speak). I just read Chasseur d'Images quite favorable test of the Sony. They seem to indicate that high ISO noise isn't nearly as bad as some early posted images would lead us to believe.
Personally, the lack of live-view is a deal breaker, so I just hope Nikon has the good sense to follow Sony when it comes to AA filtering,or ideally drop the *#¤ thing , when they present their high res DSLR.
H Jono,HI Arne
Certainly the images seem fine 'out of the box'. I've now done some A2+ prints which you really can eyeball (even my 20 year old can't see any problems).
I hear you about the live view, although they do have this 'preview' thing, which is okay if you are on a tripod.
As for the noise - well, of course the trouble is that the first thing you do is look at it at 100% - which is fine, but it's half the area of the frame with a D700, I suppose one should really compare at 50% on the Sony and 100 on the Nikon. Whatever - I've done some ISO 800 and 1600 shots tonight, and they seem to be pretty good. Although not in the same league of course. I'm not sure quite why it should be the case, but it seems to me that good low noise has a pretty direct correlation with strong AA filters: I suspect you can't get the best of both worlds at the moment (and Nikon certainly seem to be in favour of stronger filters at the right now). To be honest, this was one of the motivations of the change - it's all very well waiting until next summer for the Nikon - but if it's in a D3 sized body, has a heavy AA filter, and costs £4000 . . . .
About 70.4% for the Sony and 100 for the Nikon ought to do the trick based on the relative linear dimensions at maximum native file sizes.... I suppose one should really compare at 50% on the Sony and 100 on the Nikon. Whatever...
A stronger AA filter should decrease detail without affecting noise to as great an extent (some components of noise, eg read noise, aren't affected at all by the AA filter), whereas sharpening to get more detail in the presence of a strong AA filter will make noise more evident. Thus a strong AA filter has a net effect of increasing apparent noise for a given level of detail. I've always thought that Olympus is exacerbating their "noise issue" by using a strong AA filter.I'm not sure quite why it should be the case, but it seems to me that good low noise has a pretty direct correlation with strong AA filters: I suspect you can't get the best of both worlds at the moment (and Nikon certainly seem to be in favour of stronger filters at the right now)...
And you think you two are bad? Well, look who else has just joined! There goes the neighborhood .....And thanks , Guy, for the welcome to the forum. Looks like the place where sensible folk hang out (which kind of disqualifies Jono and me :ROTFL
Ha, that you Gareth?! Sue the author of a masterwork? I think not. I'd sue the guy who allowed said author/photographer to take the pic in his studio. I have his name and address if you need to pass it to your legal representatives :ROTFL:And you think you two are bad? Well, look who else has just joined! There goes the neighborhood .....

PS - Jono .... don't blame me for THIS purchase. The 'Autumn approaching and you need 25MP to take pictures of coloured leaves' comment isn't a valid reason ok!
PS - Q, I need some advice. I've just bought a book and there's a picture of some bloke waving his wad at me on the front cover in a crazed yet menacing manner. I'm suffering mental trauma each time I look at it. Can I sue the author ??
