Sirui Launches IndieGoGo Campaign for Jupiter Full Frame Cine Lenses

Lens manufacturer Sirui has launched a new crowdfunding campaign on IndieGoGo for its Jupiter Line of Cinema Lenses. And judging by how quickly the campaign breezed by its initial goal, it’s safe to say that filmmakers want to see these affordable full-frame lenses hit the market.

The campaign covers three T2 prime lenses that run from 24mm to 50mm focal length, with 35mm right in the middle. The lenses are designed with a larger image circle, to support larger format camera sensors and an 11 blade iris for some silky bokeh.

The lenses also enjoy a minimum focus distance of just under 10 inches (.24m), while the aperture ranges from T2-T22. The lenses are also step-less, for smooth Iris control along the entire range.

Moreover, with optics that are custom coated to prevent glare, chromatic or optical aberration, and distortion, Sirui says that the sharpness, color reproduction, and dynamic range rival any other cinema lens for shooting in resolutions up to 8K. Focus breathing is also kept to an absolute minimum, to keep the viewer fully immersed in the visual storytelling.

The Jupiter design also shows complete consistency across the entire focal range, with unified gear positioning for both iris and focus control rings, the same 92mm lens diameter, and a weight that is within .2KG of each other.

Sirui has also laid out the control rings with both imperial and metric measurements. Focus rotation for all three passes 200°, with the 50mm going a full 220°.

To accommodate most professional cinematic camera platforms, the Jupiter line of lenses will be natively available in PL and EF mounts, with adapters that also support E-mount and RF-mount cameras. The three lens set also comes with a custom-fit hard case for protection.

Sirui is also developing a 28-85mm T3.2 optical zoom with a 3x zoom ratio and a 259° focusing throw. The lens has a parfocal design so the focus remains unchanged throughout the zoom range.

The 44mm image circle easily covers full-frame and large-format sensors, and the zoom can be used on many large cinema camera systems, such as RED V-Raptor, ARRI ALEXA Mini, Canon C500 Mark II, Sony FX9, and Sony VENICE.

The super early bird price on IndieGoGo for each of the lenses is $799, with the three lens set going for $2238. Meanwhile, the 28-85 zoom will be $2319, and a set of all four will set you back just under $4400. The adapters range in price from $79-119.

After the campaign ends next month, the actual retail price will be 20% more. All lenses are due to ship starting May 13th.
