Nikon 1 18.5mm f/1.8 Lens for Mirrorless Camera System - White


About Nikon 18.5mm F/1.8 Mirrorless

The 1 NIKKOR 18.5mm f/1.8 is a normal, 18.5-mm (angle of view equivalent to 50 mm in 35-mm [135] format) fixed focal length (prime) lens with the fastest maximum aperture, f/1.8, in the 1 NIKKOR lineup. Its lightweight size makes it conveniently portable. Adoption of an aspherical lens element to the latest optical design results in extremely sharp rendering, as well as reproduction that expresses the beautiful blur characteristics and three-dimensional feel expected of a fixed focal length lens. As the lens itself is so fast, it is not only capable of capturing sharp, blur-free images indoors under dim lighting without increasing ISO sensitivity, but it also supports incredibly fast shutter speeds up to 1/16,000 s, enabling capture of photos utilizing the lens' beautiful blur characteristics even outdoors on bright, sunny days. With a weight of approximately 70 g, the 1 NIKKOR 18.5mm f/1.8 is the lightest lens in the 1 NIKKOR lineup, making it extremely easy to carry around. When used with the compact and lightweight Nikon 1 J1, J2 or V1, the incredible portability of the entire system makes it easy to take additional lenses wherever you go, increasing the possibilities and enjoyment of photography in any situation.

The 1 NIKKOR 18.5mm f/1.8 is a single lens perfectly suited to those new to fixed focal length lenses as it easily allows users to expand their power of expression through interchangeable lenses. It is best suited to scenes in which a portrait subject stands out clearly from a beautifully blurred background, whether it be at a party or other special event, or with standard portraits.

1 NIKKOR lenses continue in the tradition of the Nikon F mount, which has a history that goes back more than half a century. 1 NIKKOR lenses employ the new Nikon 1 mount, and are developed for use with Nikon 1 cameras. The optical technologies and superior image quality Nikon has long cultivated along with the latest cutting edge technologies adopted for NIKKOR lenses ensure sharp rendering not only with still images, but also movies. The 1 NIKKOR 18.5mm f/1.8 is the sixth lens in the 1 NIKKOR lineup, following the 1 NIKKOR VR 10-30mm f/3.5-5.6 normal zoom lens, the 1 NIKKOR VR 30-110mm f/3.8-5.6 compact telephoto zoom lens, the 1 NIKKOR 10mm f/2.8 slim, wide-angle, fixed focal length lens, and the 1 NIKKOR VR 10-100mm f/4.5-5.6 PD-ZOOM lens equipped with a power-drive mechanism recommended for movie recording all released last year, as well as the 1 NIKKOR 11-27.5mm f/3.5-5.6 2.5x normal zoom lens.

Great lens

Great performing lens. Found myself using the auto setting on the camera most of the time since it worked pretty well in maintaining the widest aperture and lowest iso setting needed to achieve proper exposure. Indoors it's also a great performer with faster shutter speeds than the 10-30mm lens. Now I can take pictures without having to use the flash to freeze motion in lower lit areas.

A sharp, fast lens! The nifty fifty for Nikon One


from Happy Valley Tennessee  -  Hobbyist/Enthusiast

Great 'normal' lens. Only thing missing is optical stabilization, I'm sure that will be coming in the future, but for now this lens is wonderful in corner to corner sharpness.


Great lens


from O'Fallon MO  -  Semi-Professional

This is the perfect lens for your Nikon 1 system.It's fast and well made. I returned it but I will buy it again this summer because it is the perfect lens to take close ups in the woods. Adorama returned my money within days.I buy all my photo gear at Adorama.


A great fast lens for the Nikon 1


from san leandro ca

This lens is a great in low light!! It works great on videos with both my Nikon 1 V1 and Nikon 1 J1. It matches my Nikon 50mm 1.8 d lens.


...the nifty fifty !


from Denver  -  Professional

...the nikon 1 system offers great image quality and a fun factor that is off the charts...the 18.5 continues that theme...affordable, fast 1.8 aperture, superlightweight, blazingfast autofocus, a 50mm FOV...and really, it's just GREAT !!! ...just get one and enjoy the ride with a prime lens.


Great Lens


from Hartford, CT  -  Hobbyist/Enthusiast

I bought this lens so that I could have some fast(er) glass in my V1. With kids who don't stop moving, the fast focus it provides allows me plenty of keepers.


nice lens


from ca  -  Hobbyist/Enthusiast

i mainly use this lens only and rarely use the stock. i love that its wide open at 1.8, just wish there was a focus ring on the lens.


The lens that should come with the came.


from Indiana  -  Semi-Professional

This little lens, takes me back to the days when a decent camera would ship with a fixed 50mm 1.4 (or similar) lens. Most consumer level modern digital cameras, even the quasi dslr's ship with a do it all zoom which lacks any kind of aperture. This little lens, with it's 1.8 hasn't come off the camera since I put it on. Forget the bland 10-30 (or whatever the thing is) that comes with the camera. I plan on buying the fixed 10mm, since I now consider this camera worth investing in. I wish they made a fixed portrait lens like a 135 (which would be a 50 in the the Nikon 1). I highly recommend swapping to this lens as soon as you buy your Nikon 1.


Great Product-Very Fast


from Utah  -  Casual user

So far so good, shoots very fast compared to the other nikon 1 lenses. So far it has been worth the money.

Great Camera, Great Images


from Silver spring, MD  -  Hobbyist/Enthusiast

Everyday shooting, some portraits. I love carrying this when I'm just casually shooting and don't need the big DSLR. The white looks great and different from the cameras around everyone elses neck. Easy adjustments, settings, would be great with an EVF but I get by without it. Great camera!


Sharp and Fast


from San Francisco Bay Area  -  Hobbyist/Enthusiast

This is the only choice for those who needs a 50mm(equiv) f1.8 lens. And thank goodness it is a good lens. I bought it for my V1 because none of my Nikkor FX/DX lenses come close to that focal length and aperture because of the 2.7 crop. IQ is very good. Bokeh is acceptable but not as creamy as the DX 35mm f1.8 on my D90. Overall, I am pleased with my purchase. It's a bit pricey(was expecting ~$140). It is not exactly pancake size too.
