It does have the same manual focus peaking and a sharp EVF as its big brother, so manual focus is just as fast and easy.

What People Are Saying Give it to me straight

Sensor

The A7 incorporates the lower-resolution sensor in order to use Sony's hybrid autofocus system; Sony says that it couldn't put the phase-detection pixels on the 36-megapixel sensor for the A7R.

Both new sensors have redesigned microlens arrays.
by c|net (Feb, 2014)
While most modern sensors use gapless microlenses, these also required some tweaking on the edges near the lens mount to prevent vignetting, since the sensor's such a tight fit in the mount opening.

Iso

On one hand, you can start seeing artifacts in JPEGs as low as ISO 800, but processing raw lets you alleviate the edge artifacts and recover some detail.
by c|net (Feb, 2014)
Depending upon subject matter, you can get usable JPEGs as high as ISO 6400 that print nicely as large as 13x19, and even at ISO 12800 there's a reasonable amount of retained tonal range and detail to make those shots usable when scaled down a bit.
by c|net (Feb, 2014)

Shutter

Unfortunately, it also has the same embarrassingly loud shutter.
by c|net (Feb, 2014)
Also, for those who care, Sony lets you set shutter speeds as low as you'd like - it doesn't cut you off at 1/30-second like most cameras.
by c|net (Feb, 2014)

Image quality

Even in low light at ISO 3200, it produces saturated colors without a lot of image noise.
by c|net (Feb, 2014)

Autofocus

And while it can sustain a solid burst - it doesn't slow until after about 27 shots for raw and it doesn't slow at all for JPEG - with continuous AF that's for a fairly low frame rate of 2.1fps.
