Sony announced two new models to their growing mirrorless, small-frame camera line.

The NEX-7 and NEX-5N both sport APS-C sensors, support interchangeable lenses, and video with the new AVCHD Progressive codec.

The NEX-7 carries the new 23.4 MP APS-C sensor backed up by the Boinz image processor, capable of writing 10 full-resolution images per second in burst mode.

Most of the external controls in the NEX-7 have been migrated to menus in their Tri-Navi menu system, which uses a combination of two unmarked physical dials and scroll wheel on the back to access camera functions.

The ISO rating is an eye-popping 100-16000, making that a significant leap over the NEX-5.

Video mode offers 1080p HD at 60 fps and 24 fps along with full manual control over exposure along with a selection of creative effects.

Also new to the NEX-7 is the built-in viewfinder, which is an add-on for the NEX-5N that also happens to block the port used by the flash, an unfortunate design choice.

The NEX-7 is almost the same size as the NEX-5, maybe a bit taller, and sports a redesigned grip which adds quite a bit to the stability.

Price for the NEX-7 is expected to be around $1,350 with an 18-55 f/3.5 kit lens, delivery in November.

The NEX-5N is fitted with the new 16.1 MP APS-C CMOS sensor that features the ability to select electronic first curtain to speed up capture times.

The 5N offers the same AVCHD 1080p video modes in 60 fps and 24 fps.

Menu options are similar to the NEX-7, except the 5N adds touch screen capability to the LCD back screen.

The ISO range is rated from 100 to 25,600, which means we should be able to expect some mind-blowing low light performance.

The NEX-5N offers a lot of features for $600.  Add the 18-55mm zoom for another $100.  Not exactly a pocket camera with the interchangeable lenses, but a sweet camera loaded with a lot of attractive features in a small frame.
