Sirui Vision Prime 1 VP-1 15-150mm

The Sirui VP-1 is a three-lens cine prime set with a constant T1.4 aperture and swappable mounts for E, RF, Z, and L. It's a versatile, compact option for video shooters, but optical quality is just average and there's no autofocus. Worth it if you shoot across multiple camera brands, less so if you're locked into one system.

The T1.4 aperture is the star here. It's not just fast, it's constant across all three focal lengths, so you can swap lenses mid-shoot without touching your exposure. The 1.5X max magnification is also wild for a cine prime, putting it in the top tier for macro work. But the optical score sits right around average, and the bokeh is a bit underwhelming for such a fast lens. The aspherical and ED elements help with sharpness and fringing, but don't expect the creamy, dreamy background separation the marketing copy promises. Manual focus is smooth and precise, which is what you want for video, but the lack of autofocus tanks the AF score to near the bottom of our database.

Stacked against the Tamron 28-300mm f/4-7.1 or the Sigma 16-300mm f/3.5-6.7, the Sirui set is a completely different animal. Those are autofocus zooms for stills and run-and-gun video, while the VP-1 is a manual focus cine set built for controlled shoots. The Sirui crushes both on aperture speed and macro capability, but gets smoked on autofocus and convenience. The Sony E 18-135mm f/3.5-5.6 OSS is cheaper and sharper for stills, but it can't touch the Sirui's low-light performance or cinematic control. If you need one lens that does everything, buy the Tamron. If you need a consistent cine set that moves between camera bodies, the Sirui is the only game in town at this price.

At $1,899 USD for the three-lens set, you're paying about $633 per lens. That's actually reasonable for full-frame cine primes with T1.4 apertures and interchangeable mounts. But the optical quality doesn't quite justify the price if you're expecting razor-sharp 8K footage. You're paying for the mount versatility and the consistent form factor, not for class-leading glass. If you shoot on multiple camera systems or rent your gear out, the value proposition makes sense. If you're locked into one mount, there are sharper options for less.

The Sirui Vision Prime 1 VP-1 is a weird one, and we mean that in the best way. It's a 15-150mm zoom that's actually three separate prime lenses in a set, all sharing the same compact body, gear position, and 67mm filter thread. The headline spec is the constant T1.4 aperture, which is bonkers fast for a cine lens at this price. You get full-frame coverage, manual focus only, and a mount system that swaps between E, RF, Z, and L mounts without tools.

Skip this set if you need autofocus for gimbal tracking shots or run-and-gun documentary work. Also skip it if you shoot in rain, dust, or snow, since there's no weather sealing. And if you're a stills photographer looking for a fast prime, the manual focus and average optical quality will drive you nuts. Look at native autofocus primes instead.

Buy the Sirui Vision Prime 1 VP-1 if you're a filmmaker or videographer who shoots on multiple camera systems and needs fast, consistent primes without breaking the bank. The T1.4 aperture and interchangeable mounts are genuinely useful, and the compact size makes gimbal work easy. Skip it if you need autofocus, weather sealing, or the absolute sharpest glass for 8K delivery.
