From ultra-wide to humanistic Fuji 10-24mmF4 R OIS evaluation

IT 168 evaluation fuji XF 10-24mmF4 R OIS is an ultra-wide-angle zoom lens released at the end of last year, which was officially listed in JD.COM on March 14, 2004, with a price of 6600 yuan. The appearance of this high-quality super wide-angle lens enriches the choice of Fuji wide-angle lens. (equivalent to 35mm frame) From the super wide-angle focal length of 15mm to the humanistic focal length of 36mm, combined with street sweeping and landscape shooting, the constant aperture is F4. Fuji used to have XF's 14mm and 18mm super wide-angle fixed-focus lenses, and 23mm and 27mm fixed-focus lenses with equivalent human shooting focal lengths. Now a new zoom 10-24mm integrates these lenses in focal length, which will be very practical for many photographers. Now let's take a look at this shot.

Fuji XF 10-24mmF4 R OIS lens adopts 10 group 14 lens. The newly designed optical system includes four aspheric lenses and three ultra-low dispersion glass lenses. F4.0 has a constant aperture, and its longest focal length is 36mm from the ultra-wide angle of 15mm, with optical anti-shake function. The filter size is 72mm, and the weight is 4 10g.

Evaluation summary: Fuji XF 10-24mm F4 R OIS lens is a good start for Fuji, which has no big ternary. The appearance of this lens also gives Fuji a very good wide-angle zoom lens in Junior Three. Fuji XF 10-24mm has passed the test, with good quality in all aspects, excellent resolution and good background blur effect when shooting at telephoto end, which provides a foundation for shooting humanistic themes or some simple portraits. So 10-24mm is a good small ternary lens of Fuji. I look forward to the big ternary lens of Fuji in the future, but I look forward to the full-frame camera and lens of Fuji.

Purchase suggestion: Fuji XF 10-24mm F4 R OIS lens is equivalent to the familiar small ternary lens. The biggest advantage of small ternary lens in daily shooting is its practical focal length. Moreover, this lens covers from the ultra-wide-angle scenery focal section to the humanistic focal section, which is very easy to use. It is more convenient for Fuji users who like to shoot scenery everywhere to buy this lens than to use several Fuji wide-angle focal lenses. And if you are only an entry-level user of Fuji, it is recommended not to buy this lens. 16-50mm may be more suitable for you. At present, Fuji XF 10-24mmF4 R OIS offers 6600 yuan in JD.COM. Click to view the details, the price is slightly more expensive than SLR lens.

Telescope-like design Fuji XF 10-24mm appearance

In my impression, Fuji's lenses are relatively small except 18-55mm and two other telephoto lenses. Relatively speaking, XF 10-24mm is relatively large in Fuji lens group, but compared with SLR lens, this lens is very small. The size of the lens will be related to the lens equipment and the size of the aperture. Under the condition of ensuring the image quality, the dimensions of Fuji XF 10-24mm are well controlled. The aperture of the filter is 72mm, the weight is 4 10g, and the closest focusing distance is 24cm.

▲ Fuji XF? 10-24 mm lens

This lens adopts precise, sensitive and fine-tuned metal aperture ring and focus ring design, which is also the standard of Fuji lens. The zoom ring is made of plastic and is very comfortable to operate. This material is also less likely to accumulate dust than metal materials.

▲ Three-ring design

XF 10-24 lens is made of metal as a whole, and its surface is designed by matte paint to avoid scratching the lens body to the greatest extent. A newly developed coating is added to the back of the front lens, which is not obvious in appearance.

▲ matte paint Design

The mirror body is equipped with two switch buttons: one is the lens anti-shake switch, and the other is the aperture automatic and manual adjustment switch. These two functions can be adjusted according to your own needs, such as aperture adjustment. If you need to use manual M-file or aperture priority, you must be in the closed state, and if you need shutter priority and automatic exposure, use Aout appropriately.

▲ Two switch buttons

▲ lens coating and external zoom

Fuji XF 10-24mm uses external zoom without changing the length of the mirror. Through its internal focusing system, high-speed autofocus can be realized only by driving the small lens of the middle or rear lens group without moving the large lens of the front lens group. It uses a lighter built-in lens and a new stepping motor, so it can be used with low noise.

Excellent central resolution, the image quality of wide-angle edge is slightly degraded.

Fuji XF 10-24mm adopts 10 group 14 lens. The newly designed optical system includes four aspheric lenses and three ultra-low dispersion glass lenses. When shooting with various aperture values of X series cameras, the lens modulation optimization (LMO) function can improve the resolution. So in terms of resolution, Fuji XF 10-24mm has a strong performance on the screen.

Let's test this lens in the standard evaluation room of IT 168. In this resolution test, we use Fuji X-T 1 fuselage and Fuji XF 10-24mm lens to shoot ISO 12233 resolution cards, and then use IMATEST software to get the final data. Let's look at its resolution.

10mm wide-angle end test results

▲ 10mm wide-angle end center test results

The central resolution of the wide-angle end basically hovers at 3000 lines, which belongs to the middle-upper level in the non-reflex lens. The best resolution of the center appears on F8.

▲ 10mm wide-angle end edge test results

The best resolution of wide-angle edge test results appears on F8. Based on the above central resolution results, it is recommended to use F8 aperture to take the clearest photos at the wide-angle end. The edge resolution is generally low, which can not be completely avoided in ultra-wide-angle lenses, which is a normal phenomenon. Try not to take high-definition photos with F4 and F22.

Test results of 24mm telephoto end

▲ Test results of ▲24mm telephoto end center

In zoom lens, the resolution of telephoto end is generally not high, which is a common phenomenon in zoom lens. The best resolution of the telephoto end center also appears on F8.

▲ Test results of ▲24mm telephoto end edge

As can be seen from the above figure, the best edge resolution of telephoto end also appears on F8.

From the test results, we got the best resolution on F8, and shot the test in the real scene under this aperture, and the original film 100% directly showed the viewing details. The red mark is the truncated part.

Through the screenshot, we can see that the details of the central area of this lens are well preserved and the performance is remarkable.

Summary: The best resolution of Fuji 10-24mmF4 R OIS appears under the aperture F8. When taking some high-definition pictures of landscapes or Taobao shops, it is recommended to use the aperture F8. But this shot is not suitable for Taobao merchants to shoot goods. After all, the focal length can be used more widely outside.

Excellent distortion control, no obvious dark angle.

Distortion is a very concerned problem in ultra-wide-angle lens. Some people like the super wide-angle lens with large distortion, which makes some scenes have great visual impact. Some people don't like distortion, and they always feel that distortion affects the image quality in the lens. In short, Fuji 10-24mmF4 R OIS lens will enter the state of "some people love and some people hate" no matter how distorted. Before it is too late, let's take a look at the distortion of Fuji 10-24mmF4 R OIS.

▲ Live fire test

▲ 10mm wide-angle end distortion test results

The distortion of Fuji 10-24mmF4 R OIS at the focal length of 10mm is -0.975%, which is a slight barrel distortion in a wide-angle lens. It can be seen that Fuji has high requirements for lens research and development, and tries to control the distortion in the super wide-angle lens to ensure the image quality. In the process of real shooting, you can still clearly feel the distortion of the picture in the electronic viewfinder, and the feeling of shooting from different angles is not the same.

▲24mm telephoto end distortion test results

The distortion of Fuji 10-24mmF4 R OIS at the 24mm telephoto end is 0. 125%, which belongs to pincushion distortion. There is basically no sense of deformation in the test chart, and it can be said that the distortion is controlled to an extent invisible to the naked eye. There is no problem with the subject matter of taking humanistic photos after the equivalent focal length of 35mm, so there is no need to worry about destroying the most authentic humanistic picture because of distortion.

Summary: The barrel distortion of Fuji 10-24mmF4 R OIS at the wide-angle end of 10mm is obvious, which can be clearly seen in the test chart, but this achievement is well controlled for the ultra-wide-angle focal length. However, there is no obvious distortion at the 24mm telephoto end, which is good news for people who like to shoot humanities with a 35mm telephoto lens.

The dark corner disappeared in F8.

24 mm end dark angle test

Many ultra-wide-angle lenses have obvious dark angles at large aperture, but Fuji 10-24mmF4 R OIS controls this very well, and the dark angles are not obvious at the maximum aperture F4 at the telephoto end and the wide-angle end until F8 disappears completely.

Excellent ghost control and obvious glare.

Fuji XF? 10-24mmF4 R OIS uses HT-EBC* 1 multilayer coating in the lens, which can reduce ghost images to a very low limit. The ghost seen in the test can be basically ignored, showing a small color point. Glare, Fuji 10-24mm is more obvious. As can be seen from the test chart, there are basically circles of glare near the light source.

▲ laboratory glare test

▲ Glare is also obvious in real shooting.

When shooting with this lens, it is recommended to avoid direct strong light sources. After all, a lot of glare will reduce the image quality a lot, especially when shooting scenery.

Jiao Wai is soft.

Fuji XF? The equivalent focal length of 10-24mmF4 R OIS is 15mm to 36mm, which covers the focal length of people. When shooting some human subjects, it is necessary to apply the background blur function to soften some messy backgrounds. So when testing Jiao Wai, I was surprised to find that Fuji Super Wide Angle 10-24mm can blur the soft background. There is no problem from wide-angle scenery to human nature shooting.
