This camera is really great in low light, roughly TWO full stops better than the A77/65 (not one). About 1/2 F stop noisier than the spectacular low light ability of the D600 - expected from the very similar sensor, and the loss of ~30% light from the SLT approach. But this camera is right there with the Canon 5DIII.… see more This camera is really great in low light, roughly TWO full stops better than the A77/65 (not one).

But this camera is right there with the Canon 5DIII. Like Gregory says, if you need that 1/2 stop better noise than what the SLT approach gives you, then yes, get the D600. If you like PD full time auto focus while shooting video, get the A99 (but admittedly Sony over priced this!) see less This camera is really great in low light, roughly TWO full stops better than the A77/65 (not one).

In my testing so far it's very close if not a full 2 stops better than the a77. ISO 1600 on the a77 looks about like ISO 6400 on the a99.

Now that I've been shooting with the a99, and processing the RAW files in Lightroom 4.2, I feel comfortable shooting ISO 1600 the way I used to use ISO 200 on earlier crop-sensor cameras. ISO 6400 can be noise-free but you get a softer image as a result of that, especially visible when you look 1:1. The very highest IS… see more Now that I've been shooting with the a99, and processing the RAW files in Lightroom 4.2, I feel comfortable shooting ISO 1600 the way I used to use ISO 200 on earlier crop-sensor cameras.

6400 looks pretty good. A touch noisier than the d600 but still good (especially if you're down-scaling).

What noise problem? You lose half a stop of light due to the mirror, and gain a stop (over APS-C) by going FF. The A77 has no noise problem, so this one won't either.
If you absolutely need that last half stop, maybe get the Nikon D600.
