Sirui has officially announced the general availability of its full-frame Saturn 35mm T2.9 1.6x Anamorphic lens. Initially launched in November 2022 as a pre-order, this tiny lens is smaller than a can of coke, yet covers a full-frame sensor with a 35mm anamorphic field of view. It’s intentionally small so it can be more easily used on lightweight gimbal rigs, as well as drones, where balance and lens weight is important.

Available in Canon RF, Sony E and DJI DL mount, the lens measures only 100-103mm with a weight of only 390-415g. Its weight is thanks to its use of carbon fibre on the lens barrel. Carbon fibre is much lighter than aluminium or other metals often used in lens construction while maintaining more than enough strength for a lens barrel. So while it’s still a but of a lump, it’s a lot lighter than it could have been.

As a full-frame anamorphic lens, the Saturn 35mm T2.9 is about as tiny as it gets. It’s also available in two different flare options, depending on the look you prefer. One is the more typical blue, creating that classic anamorphic look we’ve become so familiar with from movies, while the other option is a “natural” colour flare, which changes colour depending on the colour of the light source that’s causing the flare itself.

The lens is said to offer minimal focus breathing and maintains its 1.6x squeeze ratio throughout the focus range as you rack from one end to the other. As an anamorphic lens, it essentially offers two focal lengths in one. The horizontal field of view is equivalent to that of about a 22mm standard rectilinear lens. On a 3:2 sensor, that produces a 2.4:1 aspect ratio while on a 16:9 sensor you get a 2.8:1 ratio. Whichever way you cut it, it’s a nice wide field of view that’s ideally suited to use in the air.

The Sirui Saturn 35mm T2.9 full-frame carbon fibre 1.6x anamorphic lens is available to buy now for $1,299 in Canon RF, Sony E and DJI DL mounts and either Blue or Natural lens flare options.
