evaluation

[IT168] August 9, 2012, Nikon officially announced the upcoming Nikon 1 J series of new products – Interchangeable Lens Digital Camera the Nikon 1 the J2. If Nikon 1 Series products to the majority of Nikon fans a surprise, announced Nikon entered the single-power field, The J2 advent of absolute claim to be an eye, we are looking forward to the J2 will bring us new experience.

The

J2 has many improvements in design and practical performance, mainly concentrated in the body with the manipulation. We will test each of these upgrade evaluation. All in all, this upgrade of J2 we are looking forward to its specific use. Now, with our evaluation to a comprehensive understanding of the camera.

basic parameters characteristic

The

▲ Nikon of J2 main features

Nikon J2 equipped with J1 as the CX frame (1 inch CMOS) image sensor. It is worth noting, however, the Nikon official data presented show that J2 has 10.15 million effective pixels 10.1 million effective pixels of J1, more than 50 000 pixels. In the strict sense, the 50000 pixels in the age of four million pixels on this cell phone can really not worth mentioning, careless users and even ignore it. But this gap can be found on J2 in the structural design is certainly relatively J1 do fine-tuning.

Nikon 1 J2 reflector design also makes every time you release the shutter without the reflective plate lifting operation, thereby reducing the exposure of the physical processes in addition to the camera size becomes small, non-reflective plate camera as Nikon, cancel. Much can enhance the continuous shooting speed, J2 can lock the focus on electronic (high speed) shooting mode, up to 60 / second continuous shooting speed, and this is the SLR to shoot what horse can not catch up.

the J2 built-in phase detection AF system, making it both in the photo was taken, or high-definition video capture, and the focusing speed has shown a significant advantage. CX frame sensor size than APS-C format DSLR smaller, even not as good as the Panasonic Obama’s M4 / 3 camp, but this advantage is its light volume is unparalleled as a location for the “look cool still easy to carry products, Nikon weighed after the sensor size with the camera volume to make such a choice is clearly no problem. However, a smaller frame for users to worry about its quality performance is understandable.

data from the hardware point of view, J2 compared to J1 basic no special upgrade, which makes us more to look forward to quality performance in actual use of the J2.

the compact

little change shape, the display compared to J1 has been a great upgrade

get Nikon J2 is the first feeling is that the overall appearance with J1 change, still integrated into a simple, stylish design factors are truly a pleasure.

The

▲ Nikon J2 front view

Nikon J2 body size of about 106x61x29.8mm (not including protrusions), weight 237g (camera body only), almost unchanged compared to J1. Still very small, as seen from the front, very simple and smooth, Nikon 1 Department of LOGO is very striking. Although we have been playing for a long time, but still feeling its shape is too attractive.

The

▲ Nikon J2 rear view (than J1 roulette new creative shooting modes)

J1

Nikon equipped with three inches of 460,000 effective pixel LCD screen, Nikon 1 J2 3 inches, approximately 921k-dot, wide viewing angle LCD LCD screen, compared to J1 has been dramatically improved, clarity higher visibility better. Thanks to the LCD screen for a camera shooting, this is undoubtedly very useful upgrade.

J2 screen does not support touch operation, the parameter is set to be completed through the fuselage button, the buttons are all located in the back of the camera. It is worth mentioning that the wheel J2 J1 of the original four shooting modes on the basis of a new a new “creative mode” to achieve the five kinds of options.

The

▲ Nikon J2 about View

J2,

Nikon, lens color and body, there is a wide range of choice, looking from the side, and the body harmonious unity, telescopic lens can not shoot contraction to the shortest possible extent.

The

▲ Nikon J2 top view

shutter button, the video capture button and the power switch is located at the top of the fuselage, the shutter button with a metal threaded design, very beautiful in the light, Nikon J2 without an external flash hot shoe interface, built-in flash is hidden at the top of the fuselage, can flash back of the switch lever so that it pops up.

The

▲ Nikon J2 within a flash pop-up

Nikon J2

built-in L-type flash work feeling in general, the index is very low, about 5/16 (m, 100,20 ° C), but it is worth mentioning that the flash pop-up the machine is very lovely, even the evaluation male editor of the rooms are sprouting. In general talk better than nothing, the machine with a hot shoe interface, regardless of the function of the amount of index size, with a flash a critical moment is always more than anything else to no good.

The

Nikon J2 body interface is also very simple, only the most commonly used USB data interface, and HDMI high-definition signal interface, the interface protective cover at the side of the fuselage.

The

▲ Nikon J2 Bottom View

Nikon J2 at the bottom of the hole of a metal tripod, product model and encoding is also the bottom of the camera. Purchase inspection of three yards and one need look here. (Three yards in one: the coding of packaging, warranty certificate encoding, body encoding to be consistent side you have a warranty)

The

J2 with

Nikon with J1 EN-EL20 models of rechargeable lithium-ion battery capacity of 1020mAh. Do not use flash, the battery is fully charged state to meet the basic J2 day on the road shooting needs.

from the overall perspective, the appearance of the Nikon J2 with really good to see a very attractive, very compact size, can be placed directly on a handbag or jacket pocket. Compared to J1 in addition to increasing a roulette option with slightly materials and design, no major changes (the LCD screen to upgrade the appearance point of view does not come out). But the focus of specific performance with experience, how is this consideration, the following is a look at the Nikon the J2 image quality evaluation performance.

Nikon J2 resolution test

Nikon J2 compared to its predecessor Nikon J1 for the pixels change, but the effective pixels increased from 10.1 million to 10.15 million to nothing. I guess Nikon J2 should be used with Nikon J1 Similarly a sensor and effective pixel enhancement may simply be because the pixels of the sensor edge of a certain optimization, so an increase of 50,000, in theory, the five million effective pixels The effect should be reflected in the actual resolution is very small.

in testing, we use the Nikon J2 equipped with a 10mm lens shooting ISO12233 resolution (4000 lines) target for the sample under the stop and through the Imatest software to test the conclusion that the best resolution values. Nikon the J2 best resolution test results:

The

▲ Nikon J2 best resolution histogram

data from the test results point of view, Nikon J2 resolution JPEG to a straight out of the case, the horizontal resolution of about 2500 lines, the vertical resolution of about 2150 lines. RAW the turn JPGE, the horizontal resolution is prohibitively high, reaching about 3200 lines, while the vertical resolution is also increased by nearly 500 lines.

The

▲ Nikon J1 test results

data compared to the Nikon J1, in fact, the difference is not large. So it can be said that Nikon J2 is not an improvement in resolution.

Nikon J2 intelligibility test

resolution testing allows us to know the definition of the theory of a camera, but the photo shoot is not able to achieve clarity we hope better to look at the effect of the actual shooting.

The

▲ definition real film contrast scenes

The

▲ Nikon J2 the Nikon J1 real shot slice comparison

view from the actual shooting, confirmed the resolution of the test results, the Nikon J2 and J1 is almost no difference, if I do not mark the sample is taken by Nikon J1 or J2 shooting, I believe completely unable to distinguish .

comprehensive resolution and clarity of both the test results is not good the Nikon J2 quality performance, compared to J1 is no progress, which is inevitably disappointing. To actual shooting, the Nikon J2 is stronger than ordinary DC some mainstream single electronic camera or there is some discrepancy. This is mainly because the sensor size, sharpness and detail preservation is difficult to M4 / 3 and APS-C format a single power to compete.

Nikon J2 high sensitivity imaging measured

effective pixel

Nikon J2, although only 10.15 million, but for the one inch size sensor pixel density is not low, the small sensor size and high pixel density will certainly affect the J2 sense of the high imaging quality, which previously Nikon J1 and V1 are reflected.

following scenario IT168 Testing Room sensitivity standard test environment. Camera fixed on a heavy tripod gear head allows the camera to shooting a motionless stall sensitivity effect. After our photo slice of the image above the interception of the same location, as shown in the red box as shown, to see how Nikon J2 stall sensitivity in the end.

The

▲ test area

First of all, let’s turn off noise reduction JPG straight out of the RAW transfer JPG the slice comparison of the original film.

The

label from the figure above 100% of the region slice JPG straight out of Nikon acceptable sensitivity also at ISO 800. Nikon J2 screen grainy ISO100-200 is very minor, ISO400, when the screen appears the noise, significant increase in noise from ISO800 onwards, began to seriously affect the quality can be seen from the above sections. I believe that the ISO 800 quality requirements of users, and only reluctantly accepted. ISO800 above the stalls only for emergency situations.

while the RAW to JPG effect is not significantly improved, and JPG straight out of the effect is almost the same. I believe more for Nikon J2 users will still choose the convenience of JPG shooting, while the author was also so recommended.

Nikon J2 noise reduction effect can be normally open

assume

Nikon J2 provides us with a noise reduction function, let us to compare one group to open a high sensitivity noise reduction effect of contrast.

The

from the above comparison, we can see the Nikon noise reduction effect of the J2 to work at ISO 400, noise reduction effect is most obvious is effectively inhibited the screen grainy screen cleaner at the same time there will be some loss of detail.

at ISO 800, when, because of noise inhibit the screen grainy, and there is no obvious loss of detail, so the pleasure of the entire screen is enhanced. Above ISO 800, although the serious loss of detail, but compared to a rough picture, or is more acceptable. The author suggested that the high sensitivity noise reduction can be normally open.

Nikon J2,

Nikon of J1 sensitivity comparison

The resolution and clarity, Nikon J2 without any progress, but I have something to look forward to enhance sensitivity. As an upgrade product, to improve the noise reduction algorithm is the manufacturers are willing to do. Let’s take a look at the Nikon J2 and J1 high sense of contrast.

The

Based on the figure, we can easily see that the high sensitivity performance of Nikon J2 with Nikon J1 absolutely in the same horizontal line. This result so I was quite disappointed. As a result, in terms of picture quality Nikon J2 can be said that no progress.

high sensitivity test summary: Nikon J2 sensitivity at ISO 800 Shihai be acceptable, I suggest that you use ISO 400 sensitivity shooting. When shooting can be set to automatic sensitivity, the sensitivity range for ISO 100-400, compared to the Nikon J1 without any progress.

Nikon the J2 color performance test

clarity, high sensitivity imaging is an important manifestation of the definition, while Nikon J2 color performance is also worth noting, first, depends on whether it’s white balance to accurately restore the original color temperature of the object, see Nikon J2′s overall color tendency is more suitable for the performance of what the subject matter.

The

▲ white balance test standard plate

In order to know the Nikon J2 imaging style, the color test session, we let J2 equipped with a 10mm fixed focus lens, and set the automatic white balance and manual white balance shooting the standard color card (top red box area is the color test range final data), and obtained by imatest software:

The

▲ Nikon J2 manual white balance test results

test pattern reflects the difference between the Nikon J2 is the actual image color values ​​and the ideal value. Part of the figure surrounded by the gray line is the color gamut of Nikon J2 test pattern value of the Chinese color for the idealistic values, rounded blocks of color for the actual shooting. The manual white balance 29.9% beyond the sRGB color space, the Nikon J2 in the color performance of the more gorgeous, blue performance sensitive, suitable for shooting photos of the scenery theme.

The

▲ Nikon J2 auto white balance test results

Nikon J2

automatic white balance beyond the sRGB color gamut of 30.8 percent, the same color more gorgeous, but also sensitive to blue-green performance, suitable for shooting scenery class photo.

from the above two test results have been seen, Nikon J2 footage color is gorgeous, especially when shooting landscapes, easier to shoot a nice blue sky. But for the user is not prepared to late, I still recommend shooting landscapes, you can use the landscape mode, so the color will be more gorgeous.

the Nikon J2 appearance in

control experience

itself is very small J2, was only accompanied by the 10mm F2.8 biscuit head will seem relatively portable, but walking back and forth in the viewfinder. 11-27.5mm new sets of head and focal lengths 10-30 wide, but is more compact in size. Thus J2 is at first glance, the feeling of the author is smaller overall.

The

▲ single handheld grip

J2 In addition to the new orange body, the materials also made certain minor changes, the color of the fuselage using embossed design, and therefore a little better than before the piano paint the non-slip effect. However, the J2 body is too small, even small hands can not use all the finger grip.

the J2 manipulation and J1

Although the basic operation of the J2 and J1 is not caused, but for the first time using a single power, the manipulation of the Nikon J2 is certainly still a little complicated, especially the many parameter settings need to enter the menu to complete, so the next I will introduce some common features of the regulation. J1 more familiar with a friend, we can skip this part to see the J2 relatively J1 what changes in handling the details and menu.

• adjust the aperture / shutter

The

the

▲ top of the lever can adjust the aperture (A file) / Shutter (T file under)

In fact, the normal shooting, the right index finger just fall on the shutter button, while the thumb is located in the zoom in / out lever nearby, so you can always adjust parameters such as aperture, shutter.

• adjust the exposure compensation

The

▲ arrow keys to “right” to enter the exposure compensation to adjust

If you are shooting through the screen when the screen is too bright or too dark, you need to adjust the exposure compensation value. Relative sensitivity, white balance and shooting adjust for, J2 exposure compensation adjustment is relatively easy, simply by the arrow keys to “right” to enter the exposure compensation menu, and then roll the trackwheel or the arrow keys can change the EV value .

adjust the sensitivity, white balance

dedicated function keys for Nikon J2 very little body nor independent of the custom button, so the need to enter the menu for the sensitivity value and white balance adjustment settings.

The

▲ press the MENU button to enter the menu level

after

MENU button to enter a menu to select the ISO speed or white balance settings, the specific operating two similar, so here are introduced to what is more important sensitivity adjustment.

The

▲ ISO setting options

enter the sensitivity adjustment menu, we can not only select the appropriate ISO value, if you feel the need to repeatedly set the ISO is too much trouble, then, you can choose Auto ISO and limit the maximum ISO value, so that allows the camera to be decided in accordance with exposure ISO value within a range, for J2, we can choose the A800 automatic file and open the noise reduction function.

• Set the timer shooting and shooting

In order to facilitate user self-timer, Nikon J2 timer shooting set up a dedicated button, but does not contain the general camera would have burst setting function, and each timer to continue shooting after shooting the need to re-set again, this is a common problem with Nikon a single Department of power, but J2 still did not get rid of this I believe that the bug was a little disappointed.

The

▲ arrow keys left button to set the self-timer (every time settings can also suck)

and J2 in the details than the J1, J1 in automatic mode press the “F key” can be continuous shooting, new creative mode, J2, so the F key role in the automatic mode failure .

The

J2 the “F key” function failure

▲ automatic mode, default settings (machine)

J2 of the “F key” function in automatic mode failure (machine default settings), although the J1 only in automatic mode through the F key to set the shooting, but it is quite easy.

The

▲ shooting settings

Therefore, regardless of the mode in which, if we want to change the J2 burst mode need to enter the menu selection is very convenient. In fact, this feature can from the back of the arrow keys left-control, perhaps because the buttons are too small to accommodate two icons of the reasons (I guess), J2, has not changed at this point.

new creative mode for quick switching the shooting mode

the appearance of the first page introduction, the author has referred to a “creative mode” more than J1 and J2 mode dial, this mode through the “F key” can quickly switch between the eight shooting modes.

The

▲ creative mode interface

The

▲ creative mode interface

This eight kinds

mode – Night, Night Portrait, Backlight, easy panorama, soft, model effects, optional color, and P / S / A / M exposure modes, however P / S / A / M file the switch still need to enter the detailed menu can be changed. However, it is more closely tied to the user is J2 scene selection auxiliary picture is built-in camera and the initial use of white users can understand the show a variety of creative effects.

menu option less the

automatic mode

increase in creative mode, so J2 automatic camera mode menu has quietly taken place changes the same MENU button to enter the J2 can adjust the parameters of only the size of the image quality and shooting. But this division of functions and makes the shot easier, the automatic transmission is a pure fool mode, the user of the card machine with up will feel at home.

The

▲ automatic mode, the menu changes

and difficult to find J2 screen and D4, D800, the same yellowish green, but the color of the screen, Nikon has stated that the new model is more correct, it seems that Nikon after the new screen should be like this.

contraction of the lens can be controlled switching machine

and J1, J2 can be directly through the contraction of the lens to switch machines, and J1 is only through the lens zoom ring to unlock the boot menu.

The

▲ contraction of the lens can switch machine

and we use the J1, J2 tested Nikon an old lens has nothing to do with Lens through the lens switch, this feature is mainly decided by the body that is only through the lens switch machine function J2 have.

manipulation summary

: In fact, the manipulation of the main parameters on the J2 and J1, there is not much different, creative mode so that the camera mode broken down more clearly and more playable of the filter function to join. Although J2 is still left over from the many previous generations of models, but on the whole, the J2 user experience is improved.

The Nikon J2 video shooting,

well

Nikon J2 not only support 1920 × 1080 resolution HD video capture, still be set separately on the right side of a video record button. However, in the camera mode can not be directly press the record button to enter the video capture mode, through the back of the fuselage of the mode select dial to select the camera mode in order to press for video capture.

screen shot not the camera’s long, but as a not well documented for many shooting scene, the advantages of high-definition video capture will be reflected. Nikon J2 phase detection auto focus technology, theory on the focus and tracking focus performance is impressive in the embodiment, let us to test the actual shooting.

▲ Nikon J2 video autofocus test

a lot of photography camera for beginners, AF is sure to be the main way to shoot video. This way, when shooting moving objects, it is difficult to let the focus always falls on shooting the main body. However, you can see the screen to move from vision close, J2 AF is very crisp, can be very smooth, will shift the focus to a new subject, without the slightest hesitation, this is definitely thanks to phase detection focus assist function.

▲ Nikon J2 Video chasing coke test

from J2 continuous chase to focus video you can see the entire train coming, Nikon J2 is guaranteed on the front of the location of continuous automatic tracking AF, when the front was approaching after a brief loss of focus process , but soon went on to focus on in the body of the letter, Auto tracking AF performance good.

video capture summary: J2 video capture relatively J1 almost no difference, have reached a good standard, AF, tracking AF is very accurate and fast. Its video recording capability is not mere decoration or say gimmick, that it is stronger than most SLR, single power is no exaggeration. If we can resolve the holding in the stability of this problem, then, the J2 want to replace part of the consumer DV is not difficult, after all, the J2 has a larger than many consumer DV Media Converter size with good focus, tracking AF performance.

The Nikon J2 official,

proofs appreciate

diagram of

theory of test data and evaluation are able to more objectively reflect the imaging quality of the lens, but look at the proofs sorted intuitive feelings of a camera’s performance, but due to limited evaluation time, IT168 temporarily all official original film View more real film proofs in the next week, J2 new lens reviews offer for everyone.

Nikon J2 evaluating summary: quality is not the point, cost is king

relatively J1 J2 picture quality

overall there was no improvement, but the J2 upgrade the focus does not lie in the quality, cost-effective upgrade is the J2 real selling point. Because of J1 prices very close to the people while sales have been good, J2, on the basis of the the J1 compact, portable fashion, they were the improvement of functional parameters, but slightly enhance the performance of J2 pricing than J1 cheaper, so worth buying.

The

▲ Nikon J2 than J1 in the body color look better

However J2 remains a common problem of a Nikon it is a single power, especially in the viewfinder J2 in a strong light through the screen viewfinder difficult. And timer shooting every time need to re-set the timing parameters, and the timer button on the directional pad, unlike other cameras can control the shooting set, so we need to pay attention to use.
