The world’s widest full-frame non-fisheye wide-angle lens is currently the Lowa FF II 9mm F5.6 W-Dreamer ultra-wide-angle lens that will be launched soon. This lens will have Leica M, Sony FE and Nikon Z mounts. Today we will bring the shooting experience of this lens.
For this lens, there is no exaggerated size design, but a relatively small design, weighing only 350g, and it has a very high portability. However, in order to achieve the extreme wide-angle of 9mm, the lens adopts an optical design of 14 elements in 10 groups, with 2 aspherical lenses and two ED lenses, thereby ensuring the quality of the lens.
The viewing angle of 9mm is 135 degrees, which exceeds all current non-fisheye wide-angle lenses. In addition, this lens is an ordinary wide-angle lens and does not have the strong distortion of a fisheye lens, so the angle of view is more natural when taking pictures. The lens is a typical landscape lens, very suitable for shooting buildings in a narrow environment.
Let’s take a look at the actual angle of view of this lens. The above picture shows the author using the iPhone 11 Pro wide-angle end to shoot, the angle of view is 120 degrees, and the picture below shows the old frog 9mm F5.6 shooting, the angle of view At 135 degrees, the viewing angle is very wide.
The size and weight of this lens is not big, the length of the lens is only 66mm, the maximum diameter is 62.6mm, and the weight is 350g. It is a compact wide-angle lens with bulb design. This time the lens we use is still Leica M mount, we use the adapter ring to transfer to Nikon Z7 body, there will be Nikon Z native mount lens in the future.
The aperture range of the lens is F5.6-22, and the scale ruler can accurately indicate the entire range of aperture. In addition, the focus ring of the lens feels good and has an accurate focus scale. In the focus scale, a focus limit is added to the 0.7m part, which is more convenient when focusing.
It is also worth noting that because The lens is 9mm. In fact, starting from F11, the lens can achieve full hyperfocal shooting from 0.12m-∞. That is to say, starting from F11, we actually don’t need to worry about focusing.
At present, the coating process of domestic lenses has been improved a lot. The coating of Lao Frog 9mm F5.6 is purple-red, and the color is very beautiful when backlit. As a bulb head, Lao Frog 9mm F5.6 has better anti-glare performance when shooting against the light, which can suppress a large part of glare and ghosting. The rear coating of the lens uses a standard yellow-green coating design.
For the image quality of the lens, the center resolution of this lens is pretty good, but the edge vignetting is more serious, and there will be more obvious vignetting after the aperture is reduced. The author used Nikon Z7 for shooting, and the resolution of the lens is enough to meet the needs of scenery shooting.
The closest focusing distance of the lens reached 0.12 m, so you can shoot very close to get an impactful photo. In addition, the focus of the lens is very easy, and the hyperfocal distance can be easily obtained, so there is no need to worry about focusing issues for daily shooting.
The distortion control of the lens is ideal, and the edge distortion is not serious. This is a non-fisheye lens, so although the angle of view reaches 135 degrees when shooting, there will be no strong distortion.
The backlight performance of the lens is also ideal. Although the bulb head will inevitably have glare, the control of flare and ghosting is relatively good. In addition, the lens uses a 5-blade aperture design, so the starburst presents a very dazzling 10 starburst effect.
Finally, let’s take a look at more photos.
