The J1 uses Nikon's new 1-mount lens system, which was created specifically for their newer 1-series of EVIL (Electronic Viewfinder Interchangeable Lens) or ILC (Interchangeable Lens Camera) cameras. This is an all metal mount system, which gives one the feeling that it's well built and durable. To the right you can see the lens release button. When attaching lenses, you rotate the lens barrel counter clockwise in order to lock the lens in place, and clockwise to remove the lens; which is the exact opposite of many dSLR mount systems. This caused some slight confusion the first few times I swapped lenses on the J1.

In the photo above you can also see the J1's 10-megapicel CX-format (13.2mm x 8.8mm) image sensor. Nikon chose to develop an all new CMOS sensor for the 1-series, which is slightly smaller than the sensors featured in Olympus and Panasonic Micro Four Thirds modes. Labeled an AF CMOS sensor, this unit is the first in the World to include phase-detection autofocus. This allows Nikon to boast that the new sensor/AF combo allows the J1 to "deliver super-precise focusing that captures a wide range of subjects flawlessly". The angle of view is approx. 2.7x the lens' focal length to get the 35mm equivalent.

The AF system is quite impressive on the J1, which combines conventional phase detection with contrast detection, in what they call their "Hybrid AF" system. It utilizes 73 AF points across the frame, and detects which system it needs to use depending on the lighting and shooting conditions. In lower lighting, the camera will switch to contrast-detection AF, giving you can edge in difficult situations. AF modes include Single AF (AF-S), continuous AF (AF-C), auto AF-S/AF-C selection (AF-A), fulltime AF (AF-F), and manual AF (MF). You can also choose the AF-area mode from Single-point, auto-area, or subject tracking; as well as Face-priority AF. In poor lighting the system is aided by a built-in AF assist lamp.


Nikon_FT1_MA_650.JPGNikon offers a mount adapter (Nikon FT1) that allows you to use your existing Nikon F mount lenses with the J1 and other 1-series cameras. Like with the J1's lenses, you have a multiplier of 2.7x when using F mount lenses.


Lenses


nikon_j1_lenses.jpgHere we can see the J1 with three of the four current 1-series lens offerings from Nikon (as of 3/2012): The 1 Nikkor VR 30-110mm f/3.8-5.6, 1 Nikkor VR 10-30mm f/3.5-5.6, and the 1 Nikkor 10mm f/2.8.  All of their 1-seires lenses come in two color combinations; White and Black.



nikon_j1_10-30mm.jpgHere we have a close-up of the J1 with the 1 Nikkor VR 10-30mm f/3.5-5.6 lens mounted. In this photo you can see the 10-30mm in the locked position. To unlock the lens you press the black button the zoom ring and rotate the lens counter clockwise. Not only does this unlock the lens, but it will also turn on the J1. I found this option really helped capture quick shots, allowing you to just rotate the lens and shoot; instead of pressing the power button, then rotating the lens and pressing the shutter release.

This lens covers a 35mm equivalent zoom range of 27-81mm (3x).

nikon_j1_10-30mm_extended.jpgHere we can see the 1 Nikkor VR 10-30mm in the open position.


nikon_j1_30-110mm_nohood.jpgFor those who need a bit more magnification, Nikon offers their 1 Nikkor VR 30-110mm F/3.8-5.6 lens. This unit starts off right where the 10-30mm left off, leaving no gap in focal range between the two. With the 2.7x magnifier in place, this 30-110mm lens covers a 35mm equivalent focal range of 81-291.6mm (approx. 3.6x). Like the 10-30mm, this model offers built in VR (Vibration Reduction) technology, giving you addition stabilization when shooting in lower lighting or at longer focal lengths. It also boasts two high-quality ED (Extra-low Dispersion) lens elements.

nikon_j1_10mm.jpgThe last of the lenses we used with the Nikon J1 was the 1 Nikkor 10mm f/2.8 pancake lens. It offers a 35mm equivalent view of 27mm, which is nice and wide for various types of photography; street photography, landscapes, etc. With a fast f/2.8 maximum aperture, the lens also offers some excellent low light capabilities.
