SIRUI has just announced a new lineup of full-frame lenses called Jupiter. There will be three prime lenses at launch: 24mm, 35mm, and 50mm T2. Also, a 28-85mm T3.2 zoom lens will give users even more creative options. All lenses will be available in Canon EF and PL mounts. Let’s take a closer look at all these lenses!
Chinese manufacturer SIRUI started manufacturing affordable anamorphic lenses in 2019 with its 50mm F/1.8 1.33x prime for APS-C cameras. These budget-friendly anamorphic lenses are quite popular amongst independent filmmakers. SIRUI released many complementary anamorphic lenses for Micro Four Thirds, APS-C, and Full Frame cameras in a short amount of time, including the 75mm T2.9 1.6x Full-Frame, the 50mm T2.9 1.6x Full-Frame, and the 24mm F/2.8 anamorphic 1.33x to list a few.
SIRUI is now famous for launching new products via a crowdfunding campaign. They announced that a new lineup of spherical full-frame lenses would be launched on Indiegogo on May 9th: the SIRUI Jupiter.
SIRUI Jupiter 24mm, 35mm and 50mm T2 prime lenses
Let’s start with the three spherical full-frame prime lenses: the SIRUI Jupiter 24mm, 35mm, and 50mm T2. These lenses will be available in either Canon EF or PL mounts and have a lot of things in common, including:
- A maximum aperture of T2.
- The front filter diameter is 92mm.
- An industry-standard outer diameter of 95mm for clip-on matteboxes.
- The lenses have macro capabilities, with a minimum focusing distance of only 0.79ft/24cm.
- Each lens has 11 rounded aperture blades.
- Industry-standard 0.8mm pitch gears on the focus and aperture rings.
The SIRUI Jupiter lenses are made of metal and are relatively compact/lightweight. Below is a tab with the weight and length of each lens.
While the length of each lens is not identical, the focus ring’s position is similar, making lens changes quick and easy. Also, the focus throw is 200° on the 24mm and 35mm T2 and 220° on the 50mm T2.
The lens design of the 24mm T2 consists of 13 elements in 11 groups, the 35mm T2 has 14 elements in 11 groups, and the 50mm T2 features 13 elements in 10 groups.
SIRUI Jupiter 28-85mm T3.2 zoom lens
SIRUI also announced the Jupiter 28-85mm T3.2 zoom lens. This 3x parfocal zoom will also be available in either PL or Canon EF lens mounts, and various adapters will be available for Sony E and Canon RF cameras.
The lens is entirely made out of metal. It weighs 2.5kg/5.5lbs, and it has a length of 22.3cm/8.66″ in Canon EF mount.
You’ll find 0.8mm pitch gears on the focus, zoom, and aperture rings. The focus ring has a long rotation angle of 260°.
The front of the lens has a diameter of 114mm for matteboxes, but you can also screw 110mm filters at the front of the zoom.
The SIRUI Jupiter 28-85mm T3.2 lens design consists of 18 elements in 22 groups. Like the prime lenses, it has 11 rounded aperture blades. The minimum focusing distance is 70cm/2.3ft.
Price and availability
All SIRUI Jupiter lenses will launch on Indiegogo on May 9th, and they will start shipping at the same time. The prime lenses will retail for $799 each, and the 28-85mm T3.2 full-frame zoom will retail for $2.319 for early backers. The Canon lens mount adapters are $79, and the PL lens mount adapters are $119.
This SIRUI full-frame zoom lens has many designs and features similarities with the CHIOPT 28-85mm T3.2 zoom lens, so I would not be surprised if the image comes out of these two images lenses had similar characteristics. Also, both lenses are in a very similar price range, the CHIOPT being $2.899.
