The Samsung NX1 mirrorless camera and a new 50-150mm f/2.8 ED OIS S lens are already listed on B&H website (there is still no official press release from Samsung):
A large 28.2MP BSI APS-C CMOS Sensor works to produce high-resolution digital imagery while maintaining good shadow details and enhancing low-light performance throughout the camera's 100 to 51,200 ISO range.
4K Recording at 24 fps, UHD Recording at 30 fps and 1080p Full HD Recording at up to 60 fps.
As a 4K-capable camera, the NX1 is among the most compact cameras in its class. Aside from 4K, video may be recorded in Ultra-HD as well as in full HD. To help ensure that even the highest resolution video files are easy work with, the NX1 accommodates UHS-I or UHS-II memory cards and employs HEVC (H.265) compression. Additionally, video may be recorded directly to an external device with a 4:2:2 (8-bit) output signal.
Hybrid Autofocus System
The Advanced Hybrid Autofocus system utilizes 205 phase and 209 contrast-detection autofocus points to acquire focus quickly and precisely. The phase-detection method is ideal for gaining focus in an expedited manner while contrast-detection is employed to fine-tune the focus for critical applications. When combined, focusing is sharp and leads to making photos in a natural and intuitive manner.
High-Speed Performance
A 15 fps burst rate with continuous autofocus and a 1/8000 sec top shutter speed keeps even the fastest action sharp. If needed, high shutter speeds are also possible in low light with an ISO range of 100 to 51,200.
Smart Shooting Modes
A full menu of "smart" modes is available to accommodate most imaging scenarios. They include: Action Freeze, Beauty Face, Fireworks, Landscape, Light Trace, Multi-Exposure, Night, Panorama (Live), Rich Tone (HDR), Samsung Auto Shutter, Silhouette, Sunset, and Waterfall. For more direct control over the output, Aperture Priority, Auto, Manual, Program, and Shutter Priority modes can also be selected.
Clear Viewing Options
Whether filming video or taking still photos, a tiltable 3.0" HD 1036k-dot touchscreen monitor is provided for subject framing, menu selection, and image review. When use of a viewfinder is preferred, an XGA OLED electronic viewfinder is available that turns on when brought up to one's eye.
Easy Connectivity
Files saved on a memory card within the NX1 can be downloaded off the camera via its speedy USB 3.0 connection. When wirelessly accessing images stored to the camera is preferred, NFC capability allows individual files to be transferred to a smartphone or tablet with one tap. Large groups of images may be transferred using 802.11b/g/n/ac Wi-Fi, and Bluetooth 3.0 technology can be used to easily activate the Wi-Fi while allowing a connected phone to constantly feed accurate GPS data to the camera for tagging to photos and videos in real-time.
Samsung NX Lens Mount
A broad array NX-mount of lenses is available for use, ranging from wide-angle primes to long-reaching zooms. The ability to change and utilize different lenses depending on the situation at hand aids in producing captivating and more dynamic imagery. Additionally, the NX1 is compatible with the unique 45mm f/1.8 2D/3D lens that enables one-lens creation of true 3D photos and movies.
