Blazar Remus vs Sirui Saturn

A 1.5x cinema-mount line with a choice of three flare colours, against a light 1.6x carbon-fibre line for mirrorless cameras.

Sources: specs from Blazar's Remus spec page and Sirui's store, launch prices from CineD and Sirui as recorded in our database. We have not tested either line hands-on. Cells marked unverified are missing from our sources.

The short answer

Squeeze: 1.5x vs 1.6x

On a 16:9 recording, 1.5x gives 2.67:1 and 1.6x gives 2.84:1, so both get cropped at the sides for a 2.39:1 deliverable. On a 3:2 open-gate recording, 1.6x gives exactly 2.4:1 and 1.5x gives 2.25:1. See the squeeze calculator for your camera, or the Lumix S5 II guide for an open-gate body.

Flare

Remus is the only one of the two with an amber or silver option. Saturn is sold in blue or neutral; Sirui describes neutral as taking the colour of the light source. More in anamorphic flare colors.

Other 1.5x options

If you want 1.5x on mirrorless without adapters: Blazar Talon AF (Sony E, $899), Sirui IronStar ($999), or the S35 Laowa Nanomorph.
