SIURI 150mm

SIRUI has launched 35mm, 50mm, 75mm, and 100mm focal length anamorphic lenses before. This 150mm anamorphic lens, which is announced by SIRUI nowadays, is the last lens of the Venus 1.6x full frame anamorphic lineup. If you are looking for budget-friendly full-frame anamorphic lenses, this series would be a good choice.

Why Choose SIRUI 150mm Full Frame Anamorphic Lens?

There are two words that you rarely see together, especially on an affordable lens and that is full frame and anamorphic. In addition, The 150mm has a shallower depth of field, smoother blurred backgrounds, and more elongated oval bokeh than the other lenses, which separates the subject from the background. And this 150mm lens, with a minimum focus distance of 0.58m, is suitable for close-ups. And other advantages will be listed as follows. The following sections will show the features and advantages of the new lenses in detail.

Consistent in the Set

Compared with other lenses in this set, this 150mm T2.9 1.6x full frame anamorphic lens is larger in size but is still designed with the same specifications as the kit lenses. All the lenses are designed with identical gear positions and uniform 82mm filter thread, which helps users fast swap from one lens to another without using any other accessories to change focal length. Besides, the filter can be used at any lens in this set.

To keep consistent across the whole set, these lenses are all designed with full frame, matched color tone, consistent lens flares, controlled aberration, etc. Therefore,  changing focal lengths during shooting is not abrupt.

Squeeze Factor

In terms of anamorphic, there are several different popular squeeze factors including 1.33x which is what SIRUI used on their older lenses and this 150mm full frame lens is 1.6x, which is really nice and can do several things for us.

With the 1.6x squeeze horizontally, when shooting 3:2, this lens offers a 2.4:1 aspect ratio, which is favored by professional cinematographers, and photographic teams. And you will get a wider 2.8:1 aspect ratio when using this lens on a 16:9 sensor. It helps separate the subject from the background and at the same time contains more details. Thus, the images will look more cinematic.

A telephoto lens with 0.58m Minimum Focus Distance

This 150mm telephoto lens performs well optically with low distortion, which helps capture images naturally. Equivalent to a 94mm horizontally, it is suitable for portrait and still life shooting. Thanks to its small angle of view, it is convenient for users to shoot even when they are not able to walk close to the subject.

Meanwhile, the 150mm lens breaks through the limitation of other telephoto anamorphic lenses. With a 0.58m minimum focus distance, it can be used for close-ups shooting. The 150mm lens also has a shallower depth of field, smoother blurred backgrounds, more excellent foreground separation, and more elongated oval bokeh than the other lenses. Thus the subject is separated from the background.

Image Quality

In terms of image quality, this lens is sharp without being clinically sharp. The chromatic aberration and focus breathing are very well controlled as well. In addition, if you hit the lens with a light, cinematic blue lens flares will be created, making the whole image much more colorful and cinematic.SIURI 150mm

Lens Flares

Next up, we’re going to talk about a big one for anamorphic and that is flares. We can take a look at some footage in nature with a hard source in front of the lens. And then, there are some incredible flares. You can clearly see flares are very blue and saturated. The classic blue lens flares stand out for adding a Sci-Fi ambiance to your shots without being too aggressive.
