Tamron officially released this brand new product-Tamron SP35mmF1.4DiUSD lens, internal code-named F045
“The embodiment of all the optical technology and manufacturing technology that Tamron has developed so far.”-This sentence that looks at some “outstanding” is definitely not out of thin air, but as early as February this year Tamron announced this lens Commitment made when developing news. A few months later, Tamron officially released this brand new product-Tamron SP35mmF1.4DiUSD lens, internal code-named F045.
From the perspective of consumers, Tamron SP35mmF1.4DiUSD Of course it is dazzling. The focal length of 35mm and the aperture of f/1.4 is a classic, and it is a good choice that cannot be avoided on the road of photography; taking into account the humanities and scenery, there is room to play in low light and chaotic backgrounds. Only one thing is regrettable: that is why the Tamron SP35mmF1.4 lens came so late? Needless to say, the original lens of the original factory of this specification, and other sub-factory lens brands have already launched similar products, which are very popular in the market. Although Tamron had launched a SP35mmF1.8DiVCUSD lens as early as 2015, with a large aperture + anti-shake + price of less than 3,000 yuan, which brought a very high cost performance, but from the market feedback, users seem to be unwilling f/1.8 aperture.

The Tamron lens has been silent for many years in high-end fixed focus, and finally took this lens into the door of “f/1.4 aperture fixed focus lens”. I got this lens for the first time, let me appreciate the uniqueness of this lens from several different angles.
Appearance analysis: excellent and solid texture
Speaking of the appearance and craftsmanship of Tamron lens, it has been well received in these years. After breaking away from the previous calm design, Tamron lens I suddenly became younger. Naturally, this brand new product is no exception, let us quickly unpack it and find out!
Tamron SP35mmF1.4DiUSD lens packaging Tenglong SP35mmF1.4DiUSD lens package overview
The content after opening the package is relatively concise, except for the lens itself, which is the manual and certificate, and a medium-sized flannel bag is included with the lens. After getting the lens, you will feel the heavy texture of this lens. The quality of the Nikon lens used in this evaluation is 805 grams, which weighs more than a 24-105mm zoom lens.

Tenglong SP35mmF1.4DiUSD lens is painted in black, the texture tends to be between matte and bright, and the hand feels smooth. The silver decoration on the bottom is this The appearance elements of Tamron lenses during the period. When held in the hand, the size of this lens is quite satisfactory, and the 72mm diameter does not appear too obtrusive. After installing the petal-shaped hood, the appearance of the lens is more compact and capable.

In terms of optical design, Tamron SP35mmF1.4DiUSD lens uses a structure of 14 elements in 10 groups, and it is not hesitating to configure 4 LD low-dispersion lenses and 3 GM glass cast aspheric lens, the new BBAR-G2 broadband anti-reflective coating Compared with the previous generation BBAR coating, the performance of the new coating is greatly improved, greatly suppressing the occurrence of flare and ghosting. The excellent performance is evaluated in the following evaluation It is also reflected in it.

For such a classic fixed-focus humanistic lens, Tamron puts its own optical technology accumulated over the years into it. I believe Tamron has a long-standing capacity It will definitely bring more extraordinary performance in this lens.
MTF curve test
As a portrait lens, it has excellent performance under high spatial frequency The image quality is a necessary quality. We took the Tamron SP35mmF1.4DiUSD lens to the Hummingbird Testing Laboratory for MTF curve testing. The body used in the test is Nikon D810. In this test, we focused on the usual maximum aperture f/1.4 and the center two-stop aperture f/5.6 and f/8.
Let’s first look at the performance of the Tamron SP35mmF1.4DiUSD center image quality. After our tests, we found that the MTF50 value of aperture f/1.4 is 2912LW/PH, aperture f The MTF value of /5.6 is 4002LW/PH, and the MTF50 value of f/8 is 3767LW/PH. Judging from the readings of MTF50, the best aperture performance at the center image quality is f/5.6, and the value of MTF50 at aperture f/8 is also very brilliant, but slightly inferior to the performance at the best aperture f/5.6.
Continue to look at the performance of each aperture under different spatial frequencies. Let’s first look at the MTF performance of the center image quality. From the curve comparison table, the performance of the aperture f/1.4 and the center two apertures f/5.6 and f/8 have a large gap, but in fact, when the spatial frequency reaches 1500LW/ Its MTF value can still be maintained at about 0.8 at PH, and it can show a sharper picture.
From the perspective of the MTF curve, the center imaging capability of the Tamron SP35mmF1.4DiUSD lens has a very good performance, and from the edge MTF curve, the edge imaging of this lens seems to be a bit weak, even in The MTF curve at the best imaging aperture f/5.6 still has some room for improvement.
resolution real shot test
For a large aperture lens, the maximum aperture is drawn Whether the quality is acceptable to people is the best criterion for judging its picture quality. How is the image quality of this Tamron SP35mmF1.4DiUSD lens at different apertures? We fixed the camera position and took pictures from f/1.4 to f/16 in turn, and took 100% screenshots of the center and edges. The test machine As a Nikon D810.
the red box is 100% screenshot area
through the table From the screenshots, this lens has excellent performance in the center image at full f/1.4, with a slight decrease in resolution at the edges, and a slight improvement at f/2.0. When the aperture is shrunk to f/2.8, the image quality of the center and edges has been significantly improved. Through observation, it has excellent resolution performance at f/4.0-f/8.0. After shrinking to f/16 aperture, the screen again showed a slight resolution drop, which is due to interference caused by optical diffraction.
blur is almost perfect, dispersion is very slight
As a lens product that focuses on large aperture, blur effect is also the most discussed topic for large aperture lenses, so this new Does the Jin player have excellent blur performance? Here I shot the blur performance from f/1.4 aperture to f/16 aperture, and the focus distance has been selected as the closest to make the blur more prominent.

Through the degree of flare dispersion, you can feel that the blur under f/1.4 is exceptionally dreamy. On the edge of the picture, there is a certain caliber erosion phenomenon, which is more obvious in the lens below 50mm, which is a conventional physical phenomenon. The light spot under the maximum aperture is also very soft and round, thanks to the use of 9 aperture blades, there is no obvious bilinear feature outside the focus, and the image quality under more large apertures can also refer to the sample at the end of the article.
Dispersion, glare and starburst test
This series of tests mainly examines the application effect of this Tamron SP35mmF1.4DiUSD lens under complex conditions. The first thing to do is the dispersion test, which is a situation that often occurs in general large-aperture lenses at the beginning, and it will get better as the aperture shrinks. Of course, Tamron SP35mmF1.4DiUSD is naturally no exception, but it took me a lot of effort to capture the dispersion picture. In other words, under normal circumstances, this lens has almost no dispersion. In a high-contrast scene, I used Tamron SP35mmF1.4DiUSD to capture the dispersion, but such slight dispersion can be easily removed in the later software.

I put the glare and starburst tests together, in the face of strong direct sunlight , This lens not only does not show the dispersion that is obvious enough to affect the image quality, but with the gradual reduction of the aperture, there is also a significant starburst effect. It’s just that at f/1.4-f/2.8, there are vertical lines in the highlights, some of which affect the visual beauty, and when the aperture is reduced to f/5.6, the starburst effect gradually appears until f/8.0 starts to be significant.
Tamron SP35mmF1.4DiUSD lens backlight scene and astronomy reality take samples
I encountered a more prominent backlit scene, so I took a more prominent sample. At this time, the sunlight was so dazzling that I couldn’t look directly at it. I took this photo after narrowing the aperture to f/8. You can see a certain glare on the diagonal angle of the screen.
Vignette and distortion test
As a wide-angle lens with a focal length of 35mm, vignetting and distortion test is necessary. Regarding vignetting, especially the vignetting under large aperture is usually more obvious. Through a series of shooting, I have observed that the vignetting of this Tamron SP35mmF1.4DiUSD lens is more obvious within f/2.8, and the aperture is closed to f It has improved after /4, so when shooting blue sky or single-color scenes, pay attention to shrink the aperture.

In a distorted shooting scene, I shoot three sets of images at different shooting distances in the same scene, and examine the distorted images when the focus groups are in different positions. The three photos were taken 1 meter, 3 meters and 5 meters away.

usually when shooting with 35mm, More use of shorter shooting distances, so the distortion at 1 meter and 3 meters is very slight, and the edges are only slightly distorted. When shooting from 5 meters away, we can see obvious barrel distortion through the corners. The straight lines at the upper and lower ends of the screen are distorted to a certain extent, but they are also very slight. There is no image for shooting and vision.
Appreciation of Environmental Portrait Samples
The greatness of the 35mm lens lies in the performance of environmental portraits, so portrait shooting has also been added to my testing session. Here we bring you a group of outdoor environment portrait samples. All samples were taken by Nikon D850, and the photos were all original NEF converted to JPEG and exported. The file size was only slightly compressed without any post adjustments. All samples can click to enlarge and download the original image.

through portrait shooting, you can feel this The overall performance of the lens has strong advantages in all aspects. All the samples are shot at the maximum aperture, and involve multiple scenes from full body, bust to bust, bringing different visual senses and spatial changes. The focus accuracy rate under actual shooting is very high, and the sharpness in the focus is also amazing-especially when shooting portraits, the accuracy of the human eye focus is even more important, allowing me to compose or command more calmly Model modeling has brought a very high success rate for shooting.
More samples and summary
35mm lens is also my favorite focal length, very suitable for off-camera street shooting, especially in complex environmental backgrounds or low-light situations. You can take pictures calmly. The advantages brought by the large aperture can also make the background completely blurred, highlight the subject and atmosphere, and bring a beautiful visual experience. From the previous evaluation, I have already felt the good quality of this lens, and the personal shooting experience made me even more fond of this lens.

Tamron SP35mmF1.4DiUSD lens experience summary:
At the end of writing, I don’t want to mention more about the reflection on the book data, but want to talk more about the actual hands-on experience. Although the evaluation time was not long, this lens still left a deep impression on me. The first is the most direct aspect of shooting-that is focusing. The focus motor of this Tamron SP35mmF1.4DiUSD lens has no hesitation. It can focus at the moment of half-pressing the shutter, which is accurate and stable. In addition, the texture shows that Tamron has worked hard in appearance and materials in recent years, smooth and delicate. The mirror body makes people love it, and it really feels worthwhile.
Next is the picture quality. Thanks to the 45.7 million high-pixel Nikon D850 used in the experience, the high-resolution performance of the lens is an exceptional test. After shooting through portraits and “sweeping the street”, the picture still has extremely high sharpness and detail performance after zooming in to 100%, even when it is fully opened, it can be seen that the resolution performance of this Tamron SP35mmF1.4DiUSD lens can be “hello Full” high-pixel sensor.
At the end of the evaluation, I want to express my love for the 35mm focal length again. It covers a wide range of subjects and has a high degree of “affinity”, which is different from 28mm or 50mm. It is also the preferred focal length for advanced photographers. Presumably one of the reasons for Tamron’s move to launch this SP35mmF1.4DiUSD is to allow more people to enter a deeper field of photography through this focal length, and to “call” Tamron with such a comprehensive quality lens. !
