2) Lens Handling and Build

If you have used Nikon Nikkor lenses in the past, you will not be disappointed with the new Nikon 1 lenses. The Nikon 1 30-110mm VR is built very well, despite its relatively compact size (for a telephoto lens). The base of the lens barrel seems to be made with the same tough plastic Nikon uses in its DSLR lenses. The thick rubber zoom ring with a plastic base has pretty good traction to easily zoom in and out with fingers and sits in between two thin metal rings, one of which has focal length markings on it. The top of the lens has another metal ring, which is there for aesthetics. The lens employs a retractable lens mechanism, similar to the 1 Nikkor VR 10-30mm f/3.5-5.6, which reduces the size of the lens to approximately 61mm and locks it in place when fully retracted. Here is a size comparison between 1 Nikkor lenses:

The barrel is fully extended at 110mm focal length, which almost doubles the length of the lens, so it is definitely nice to be able to collapse it when not using it. Nikon put plenty of thought into the new Nikon 1 lens line-up and developed the CX mount from scratch. Compared to the current Nikon DX/FX mounts with 8 contacts, the Nikon 1 lenses and cameras have a total of 12 contacts, which allows for more communication between Nikon 1 cameras and lenses. As a result, many of the lens functions are now controlled by the camera, so all the extra buttons and switches have been eliminated. Even the manual focus ring has been removed to simplify lens operation. There is only one button on the lens located on the zoom ring and it serves a dual purpose – it is used to collapse or extend the lens and to turn the camera on. I really like that the camera turns on when the lens is extended – one less thing to do when taking pictures (sadly, collapsing the lens does not turn the camera off). Another positive outcome of the new CX mount with extra contacts is the ability to upgrade lens firmware through the camera, which has never been possible before. Now you see an extra “L” firmware in addition to the traditional “A” and “B” under “Firmware version” in camera setup menu, which shows what firmware the lens is running on. Nikon has already identified and resolved a serious problem with Vibration Reduction on the Nikon 1 30-110mm VR lens and released a firmware update.

Just like the rest of the Nikon 1 lenses, the Nikon 1 30-110mm has a metal mount, which is surprising, because lenses of this caliber from Nikon typically have plastic mounts. This is great news for the Nikon 1 system owners, because it means that all future CX lenses will most likely have metal mounts as well, even on cheap zoom lenses. On the other hand, the rubber gasket on the lens mount that Nikon has been putting on all new AF-S lenses is absent, which could make the lens and camera more susceptible to dust. As of now, none of the Nikon 1 system components (including all current lenses) are weather sealed. On a positive note, I have used the Nikon 1 30-110mm f/3.8-5.6 VR in cold, windy and very dusty environments and I did not have any issues with dust specks making their way into the camera or the lens.

Despite its compact size, the Nikon 1 30-110mm sports impressive optical features such as Vibration Reduction (VR), Super Integrated Coating (SIC), Internal Focusing (IF) and Silent Stepping AF Motor (STM). Vibration Reduction is Nikon’s term for image stabilization, which is a very useful feature in low light situations, where camera shake and slow shutter speed can cause images to be blurry. Super Integrated Coating helps reduce lens flare and ghosting. Internal focusing means that the lens barrel does not change when the lens focuses. And finally, Silent Stepping AF Motor is a brand new motor specifically developed for the CX lenses, which allows for super fast and near-silent autofocus operation.

The Nikon 1 30-110mm f/3.8-5.6 VR has a complex optical design consisting of a total of 18 lens elements (in 12 groups), 2 of which are aspherical elements. Aspherical elements greatly reduce lens aberrations such as Spherical and Chromatic Aberration and significantly increase lens sharpness. Even the Nikon 50mm f/1.4G does not have a single aspherical element by comparison.

Unlike the Nikon 1 10-30mm VR kit lens, the Nikon 1 30-110mm VR comes with a plastic “HB-N103″ lens hood. Nikon packed the lens hood with the lens for a reason – telephoto lenses are typically much more prone to ghosting and flare than wide-angle lenses. See more info about this under “Ghosting and Flare” section further down below.

3) Autofocus Performance and Accuracy

As I have already pointed out in my Nikon 1 V1 Review, the new autofocus system on the Nikon 1 system is phenomenal when compared to other mirrorless competitors. It is very fast and accurate, thanks to the hybrid autofocus system that Nikon specifically developed for the Nikon 1 cameras. Hybrid autofocus is a combination of phase and contrast detect AF that work together to obtain quick and accurate focus. For the much faster hybrid autofocus operation, Nikon had to develop a brand new AF lens motor called “Silent Stepping AF Motor” (STM). Compared to the “Silent Wave Motor” (SWM) that Nikon uses on its latest AF-S lenses, STM is much quieter and quicker.

I had a very positive experience with autofocus performance and accuracy of the Nikon 1 30-110mm lens. It truly does acquire focus quickly, silently and most importantly, accurately. I shot several hundred images with the 30-110mm lens and I had a hard time finding images that were out of focus. Large depth of field due to the small 2.7x crop factor sensor surely plays a role here, but I have shot with point and shoot cameras with even smaller sensors before and managed to get a lot more out of focus images.

4) Vibration Reduction

The Image Stabilization / Vibration Reduction technology found on the Nikon 1 30-110mm f/3.8-5.6 lens is very similar to the VR technology found on modern DSLR lenses – it is very effective when shot at slow shutter speeds. There are, however, some differences in the way VR is deployed on the new mirrorless cameras versus DSLR lenses. First, VR does not engage on DSLR lenses unless the shutter button is half-pressed (or AF-ON pressed). This is not the case with the Nikon mirrorless cameras – when VR is turned on in camera setup, it is constantly on. You do not have to half-press the shutter button – it will always be active. This seems to be a flaw in the Nikon 1 system design, because having VR turned on constantly will have its toll on battery life. Second, VR is no longer controlled through lens switches, but rather from inside the camera menu (as reported earlier). Lastly, for some strange reason, both the Nikon 1 J1 and V1 cameras were shipped with VR turned on in “Active” mode. This is rather strange, because the active mode is supposed to be used when a person stands on a moving platform (inside a car, on a boat, etc). Not sure if this is a firmware issue, but it would be interesting to find out exactly why Nikon decided to do that. Despite these differences and reported issues, Vibration Reduction works great. I would leave it on “Normal” mode within the camera setup and only turn it off when mounting the camera on a tripod.

5) Lens sharpness, contrast and color rendition

As I reveal in my sharpness tests in the subsequent pages of this review, the performance of the Nikon 1 30-110mm f/3.8-5.6 VR is very good throughout the focal length of the lens and its aperture range. You can see many examples of lens sharpness taken in a controlled environment in the next page, along with comparisons against other lenses.

A quick note on lens sharpness that generally applies to all Nikon 1 Nikkor lenses. Due to the small size of the sensor and the nature of compact optics, an aperture of f/5.6 is rather small and often represents peak lens performance. While diffraction negatively effects images on DX and FX sensors above f/8-f/11, it greatly impacts lens performance at anything smaller than f/5.6 on CX sensors. In the case of the Nikon 1 30-110mm lens, its maximum aperture of f/5.6 on the long end means that you are at its peak performance when it is wide open and stopping down the lens only decreases image quality. This is yet another negative consequence of a small sensor camera design.

6) Bokeh

Isolating subjects from the background with a small-aperture zoom lens is a challenge due to its larger depth of field. This becomes even a more difficult task on Nikon 1 cameras, because of their small 2.7x crop factor sensors. While depth of field and the size of background highlights depend on multiple factors such as focal length, aperture, camera to subject distance and subject to background distance, the quality of Bokeh largely depends on lens optics. If you are able to get close to your subject while keeping the busy background further away from the subject, you can get a decent-looking bokeh, as long as you are shooting at maximum aperture and zoomed in a little. The 1 Nikkor VR 30-110mm f/3.8-5.6 lens is equipped with a rounded 7-blade diaphragm, which helps in obtaining circular bokeh highlights. Here are a couple of examples of bokeh when shot at large apertures:

Once Nikon releases fast f/1.2-f/1.8 prime lenses, I will look into their bokeh performance in more detail.

7) Vignetting

As for vignetting, the Nikon 1 30-110mm has the most amount of vignetting wide open at the wide end at 30mm, which stays about the same at 40mm, then gradually decreases in the mid range and eventually almost disappears at around the 80mm mark. Stopping down the lens to f/5.6 or f/8.0 (above 80mm) will significantly reduce the effect vignetting, as expected:

RAW shooters will see more vignetting in their images, because vignetting is automatically reduced on JPEG images by camera firmware. If vignetting is an issue for you, it is easy to fix in post-processing, so I would not worry about it. Adobe has not yet added a lens profile for the Nikon 1 30-110mm f/3.8-5.6 VR into Lightroom or Camera RAW, but we should be seeing it in upcoming updates pretty soon. Once it is added, you will be able to get rid of vignetting with a single click through the Lens Corrections sub-module in Lightroom / Camera RAW.

8) Ghosting and Flare

As I have already pointed out, telephoto lenses are typically much more prone to ghosting and flare than wide-angle lenses. Although the Nikon 1 30-110mm VR features Super Integrated Coating, I would not use it without a lens hood or shoot it against the sun. You will especially see a significant decrease in contrast when the sun is outside the frame and sun rays reach the front element of the lens – a very normal occurrence on all telephoto lenses.

9) Chromatic Aberration and Distortion

Chromatic aberration is controlled well, with the highest levels of CA at 30mm and 110mm marks. There is a modest amount of barrel distortion on the widest end at 30mm, which flattens at around 40mm. From there it then switches to a very slight pincushion distortion all the way to 110mm. I would not worry about chromatic aberration or distortion, since you can easily remove them in Lightroom or Camera RAW after a lens profile comes out.
