Ultra macro vs. cine macro: the core decision
An ultra macro lens is a specialised optic that lets you photograph subjects at very close distances and high reproduction ratios, often beyond life‑size, making tiny details fill the frame and demanding precise focus control, careful lighting, and a stable working distance for both scientific imaging and creative macro photography gear setups. For most shooters, the choice here is simple: Laowa’s Aksen series is the better tool if you care about extreme magnification and repeatable studio workflows, while Sirui’s Vision Prime 150mm T4 1.5x Macro suits filmmakers who need a macro cine lens that integrates smoothly into a full-frame cine kit. In practice, that means still and hybrid shooters chasing insects, textures, and technical specimens will gain more from Laowa’s parfocal zoom macro design, whereas narrative crews and product videographers will prefer Sirui’s cinema-grade handling and mount flexibility.

Laowa Aksen: parfocal zoom for extreme magnification
Laowa’s Aksen 45mm f/2.8 1–5x Ultra Macro APO and 17.5mm f/1.7 5–10x Ultra Macro APO form a full-frame parfocal zoom ultra macro lens series aimed at filling a long-standing gap in the 1–10x category. According to the manufacturer, this series addresses a market where serious macro photographers, professional scientific users, and hobbyists previously relied on high-cost, complicated DIY setups to reach extreme magnification. The defining feature is the parfocal zoom macro design: focus stays locked while you change magnification, so you do not need to refocus or shift your camera and lights every time you zoom. Working distance stays fixed—40.35mm on the 1–5x and 22.48mm on the 5–10x—and the fully internal zoom mechanism prevents the barrel from extending into your diffusion or subject. For the highest magnifications, the optional built-in coaxial light block on the 5–10x helps you control illumination right at the subject.
Sirui Vision Prime 150mm T4 Macro: cinema-first macro cine lens
Sirui’s Vision Prime 1 series is a line of full frame cine lenses designed for efficient professional workflow, and the 150mm T4 1.5x Macro continues that approach as a dedicated macro cine lens. The lens uses industry-standard 0.8 MOD gear rings for both focus and aperture, with uniform gear positions across the range so crews can swap focal lengths without moving focus pullers or iris motors. It adds a stepless aperture ring with detailed T-stop markings and a generous 270° focus throw, giving focus pullers precise control, especially at close distances. Sirui’s patented versatile mounting system lets users change the native Sony E mount to Canon RF, Nikon Z, or Leica L with supplied adapters, avoiding shims and expanding compatibility for multi-camera setups. Combined with a minimum focus distance of 0.29 m at 150mm, the lens offers 1.5x macro magnification that balances close-up detail with a comfortable working distance for motion production.
Which lens suits which macro photography workflow?
Your choice between these two pieces of macro photography gear comes down to whether your work is dominated by still/scientific close-ups or cinema projects. If you regularly shoot subjects that demand extreme magnification—think 5–10x textures, scientific specimens, or tiny insects—the Laowa Aksen series is purpose-built for that task with its 1–10x coverage and fixed working distances. Its parfocal zoom macro design speeds up studio sessions where any refocus disrupts alignment or lighting, and the coaxial light option further tilts it toward controlled, technical workflows. On the other hand, if you operate as part of a film crew or build your own cine kit, Sirui’s Vision Prime 150mm T4 1.5x Macro fits more naturally. It emphasises cinema integration, with build quality geared to rigs, a stepless aperture, uniform gear positions, and a mount system that can be swapped among Sony E, Canon RF, Nikon Z, and Leica L bodies without shims. Its magnification is lower, but its handling is tailored to moving images.
Buy if / Skip if
- Buy the Laowa Aksen 1–5x or 5–10x if you need ultra macro lens coverage from 1x up to 10x for scientific or technical close-ups where extreme magnification matters more than cinema integration.
- Skip the Laowa Aksen 1–5x or 5–10x if your priority is a unified cine set with standardised gear positions and you rarely go beyond 1.5x magnification.
- Buy the Sirui Vision Prime 150mm T4 1.5x Macro if you want a macro cine lens with full-frame coverage, stepless aperture, and cine-standard gearing that fits neatly into professional film workflows.
- Skip the Sirui Vision Prime 150mm T4 1.5x Macro if your main goal is extreme magnification above 5x and you need parfocal zoom behaviour with a fixed working distance.
