The Nikon 1 lenses test and reviewTuesday November 29 2011
A few weeks ago, Nikon announced the Nikon 1 series that we had the chance to test immediately. For this new format of camera, Nikon also designed a completely new format of lenses, the “Nikon 1 mount,” for which we are publishing the measurements today.
Nikon put a lot of effort to design lenses that offer the best balance of image quality and portability, and apparently it paid off. Let’s look closely at how these lenses perform compared to their direct competitors.
Nikon 1 NIKKOR 10mm f/2.8 (equivalent to 27mm):
- Resolution: With a score of 41lp/mm, sharpness is just average. Resolution is optimal at f/5.6.
- Distortion: Visible but very weak. (This is surprising in a positive way, given that the distortion for this kind of lens is generally stronger.)
- Transmission: No noticeable flaws.
- Vignetting: Strong at f/2.8, with a loss of up to -1.4 EV. It stabilizes at f/4, with a loss of only 1/3 EV in the corners.
- Chromatic aberrations: Important at f/2.8, but diminishing progressively as one closes the aperture.
Nikon 1 NIKKOR VR 10-30mm f/3.5-5.6 (equivalent to 27-81mm; this lens is part of the Nikon 1 kit):
- Resolution: With a score of 39lp/mm, sharpness is just average. Resolution is optimal at 10mm f/4.
- Distortion: Visible at 10mm (similar to the Nikon 1 NIKKOR 10mm f/2.8), and weak for other focal lengths.
- Transmission: No noticeable flaws.
- Vignetting: Reasonable for this kind of short focal length, with a maximum loss of up to –0.6 EV. There is no loss starting at f/5.6 for 10mm, 14mm, and 24mm focal lengths. To overcome the phenomenon at 30mm, one must shoot starting at f/8.
- Chromatic aberrations: Very good, diminishing as the focal length increases.
Nikon 1 NIKKOR VR 30-110mm f/3.8-5.6 (equivalent to 81-297mm):
- Resolution: With a score of 39lp/mm, sharpness is just average. Resolution is optimal at f/5.6, but only in the image center.
- Distortion: Visible but weak.
- Transmission: No noticeable flaws.
- Vignetting: Globally “very correct,” with a maximum loss of up to –0.9 EV, and negligible or nonexistent for all focal lengths starting at f/5.6. It is worth noting that there is no vignetting until 2/3.
- Chromatic aberrations: Very good, no noticeable problems.
Globally, these zoom lenses and the fixed-length lens are of average optical quality. This said, they do have some attractive features:
The Nikon 1 NIKKOR 10mm f/2.8 is very light (77g) and very compact, thus transportable... but not very versatile.
The Nikon 1 10-30mm and the Nikon 1 30-110mm are also quite light (115g and 180g, respectively). The two lenses together cover a wide range (the equivalent of 27–297mm), making them useful in most situations that amateur photographers will encounter.
A new “video” lens from Nikkor
The most unusual (and best!) thing about this zoom lens is that there isn’t a manual focusing ring. Instead, it uses a “T-W” drive on the lens itself to change focal lengths, which helps the user zoom in and out smoothly. In addition, the rate of zoom change is more or less proportionate to the amount of pressure on the drive — very fun for shooting video.
Here are the performance results and technical characteristics of this video lens (tested on the Nikon 1 V1):
- DxOMark Score: A weak 6, understandable in light of the low-light performance of the Nikon 1 J1 and V1 sensors. This DxOMark score, particularly its low-light component, demonstrates once again the limits of the Nikon 1 cameras.
- Resolution: At 40 lp/mm, this lens has good sharpness for this type of equipment, with higher resolution at 30mm than at other focal lengths. The 10mm focal length becomes interesting at f/4.5-5.6.
- Distortion: Visible at all focal lengths, it is at its weakest at 30 mm.
- Vignetting: Darkening is especially present in the last third of the field, where one can lose up to -0.9EV. This said, one good point is that there is no measurable loss of light on 2/3rds of the field.
- Chromatic aberrations: Important in the corners at 10mm and 100mm; once again, 30mm seems to be the optimal focal length.
Nothing surprising about the results for particular lens and lens type, which shows reasonable quality at 10mm and 30mm. However, at 530g, this is a fairly heavy lens. We expected something lighter, particularly for a camera that one might want to carry in one’s pocket.
In practical terms, the Nikon 1 NIKKOR VR 10-100mm f/4.5-5.6 PD-ZOOM has been well thought-out for shooting video. As a lens for shooting still images, it’s not very interesting, given that it is heavier than both the Nikon 1 NIKKOR VR 10-30mm f/3.5-5.6 and the Nikon 1 NIKKOR VR 30-110mm f/3.8-5.6 put together, and especially since its image quality is only equivalent to these lenses, not better.
Let’s compare how these new Nikon lenses perform on Nikon 1 cameras against the performance of similar lenses on other cameras.
Our goal, by the way, is not at all to denigrate the Nikon 1 cameras in comparing their lens quality results to those of the Nikon D3X and other cameras, since this would be entirely unfair (given that the different kinds of cameras are not comparable). Rather, we are using these measurements to show the relative strengths and weaknesses of these new lenses.
Nikon 1 NIKKOR 10mm f/2.8 vs Nikon AF-S NIKKOR 35mm f/1.4G:
Let’s start with a comparison a comparison which could look completely unfair: Nikon 1 versus full-frame: Nikon 1 NIKKOR 10mm f/2.8 on the Nikon 1 V1 versus Nikon AF-S NIKKOR 35mm f/1.4G on the Nikon D3x
- Resolution: 41 lp/mm for the 10mm and 52 lp/mm for the 35mm — only 11 lp/mm difference, which is not very big when one considers the enormous difference in quality between the two Nikon sensors. Thus the resolution of the 10mm is quite excellent.
- Chromatic aberrations: 15µm for the 10mm and 14µm for the 35mm, meaning that both lenses are similar in this regard.
Nikon 1 NIKKOR VR 10-30mm f/3.5-5.6 vs Nikon AF-S DX Zoom-Nikkor 18-55mm f/3.5-5.6G ED II vs Olympus ZUIKO DIGITAL ED 14-42mm F3.5-5.6:
Let’s now see how the 10-30mm compares with dSLR kit lenses: 10-30mm on the Nikon 1 V1 versus 18-55mm on the Nikon D300s versus 14-42mm on the Olympus E620:
- First observation: The 10-30mm achieves the same DxOMark score of 7 as the lenses in its competitors’ kits, but with a smaller sensor, so it is a serious rival.
- Resolution: At 39lp/mm, the results for the 10-30mm on the Nikon 1 are as good as for the 18-55mm (44lp/mm) and the 14-42mm (34lp/mm). A solid performance.
- Chromatic aberrations: Better corrected on the 10-30mm (7µm) than on the 18-55mm (10µm) and the 14-42mm (8µm). The differences are visible on the maps.
Nikon 1 NIKKOR VR 30-110mm f/3.8-5.6 vs Nikon AF-S VR Zoom-Nikkor 70-200mm f/2.8G IF-ED vs Nikon AF-S VR Zoom-Nikkor 70-300mm f/4.5-5.6G IF-ED:
And finally, a comparison among entry-level telephoto lenses: 30-110mm on Nikon 1 V1 versus 70-200mm on the Nikon D300s versus 70-300mm on the Nikon D300s:
- Resolution: At 38lp/mm, the results for 30-110mm closely follow those for the two Nikon super-zooms (45lp/mm for the 70-200mm and 42lp/mm for the 70-300mm), thus excellent by comparison.
- Chromatic aberrations: Better corrected on the 30-110mm (6µm) than on the 70-300mm (16µm), and equivalent to the 70-200mm (5µm).
Relatively speaking, the Nikon 1 lenses are of very good quality if one takes into account the differences in size and performance of the tested sensors:
The Nikon 1 10mm is an excellent substitute for a 27mm lens.
The Nikon 110-30mm is comparable to the lenses found in Nikon and Olympus kits.
The Nikon 130-110mm holds up well against Nikkor 70-200 and 70-300 lenses.
In the course of testing, we perceived that the quality of the JPEGs that the cameras produced was far less than excellent. This is a shame, considering the potential for the same kind of excellence as seen with RAW images.
