So SNR or noise - not much difference, which seems to be confirmed by the DPreview images. But in terms of dynamic range (which is perhaps harder to assess by eye) - the A7s does appear to be delivering the goods.
Which makes that sensor perfect for a 'wedding camera', where DR is usually more important than resolution and some wedding photogs actually prefer the smaller files size for rapid-fire work and faster PP on huge batches.

Not to mention the video capability.... That's a very nice sensor. I'll still take 36MP any day, though, unless/until there's a real SNR advantage to something smaller, but even then it would need to be significant to make up for the resolution loss.

EDIT: A7s doesn't show a DR advantage until after ISO 800 - but then it really pulls away impressively. For base-ISO shooting (landscape, etc) the D800 would better, for low-light shooting, the A7s - in terms of DR.

That is why Sony gives you a choice 12mp, 24mp and 36mp sensors. For 50-3200 iso the 36mp A7r makes more sense.
