So how does the A7 compare with the A99 and Nikon D610? DxO (Click here) writes:

Unsurprisingly perhaps, compared with the Nikon D610 and the firm’s SLT A99, both using a similar full-frame 24-Mpix CMOS sensor, the results are very close. Color depth between the three is similar and the A7 sits between the two with regard to the dynamic range, just +0.2 Ev separates the Nikon. However, it’s the low light performance that divides the two Sony models. While the A7 has a + ½ stop advantage over the SLT-based A99, the Nikon has a +1/3 stop over the A7, presumably on account of the latter model’s modified sensor.

And Photogrpaphyblog (Click here) posted the full A7 review:

After shooting with both the A7 and the A7R side-by-side, we’d be hard-pushed to choose between them, as both are remarkable cameras in their own right. On paper at least the A7 should offer faster auto-focusing and less noise at high ISOs than the A7R, but in reality there’s not a big enough difference between the two cameras in either regard. Instead we’d choose the A7 instead of the A7R because it’s significantly cheaper, it produces more manageable file sizes, has a higher flash sync speed, slightly faster burst shooting and a quieter shutter release.
