Sirui VP-1 Vision Prime Full-Frame 15mm T1.6, 75mm T1.4 & 150mm T4 Cine 3-Lens Set

The useful spec is the 46mm image circle

The VP-1 Vision Prime lenses are listed as full-frame cine lenses with a 46mm image circle. That matters for hybrid camera operators because it puts the set in the zone needed for full-frame mirrorless coverage rather than Super 35-only use.

The three focal lengths in this set are not redundant:

• 15mm T1.6: wide coverage for interiors, handheld proximity, gimbal work, and tight spaces.
• 75mm T1.4: short telephoto with a fast transmission rating for controlled depth and lower light levels.
• 150mm T4: longer compression, but with a slower T-stop than the rest of the group.

That last point needs attention. A 150mm T4 does not cut like a T1.4 lens in exposure terms. If the scene is lit around the 75mm wide open, the 150mm forces a different lighting or ISO decision. That is not a defect by itself. It is a production tolerance to plan around.

Sirui originally announced the VP-1 Vision Prime full-frame cine series with 24mm T1.4, 35mm T1.4, and 50mm T1.4. The 15mm, 75mm, and 150mm expansion gives the line a wider spread across focal lengths. No Film School also frames this as an expansion of the VP-1 Vision Prime full-frame cine set.

Mount flexibility is the main production argument

The lenses are native Sony E-mount, according to Newsshooter, and ship with user-changeable mount adapters for Canon RF, Nikon Z, and Leica L. That is the strongest operational pitch here.

For owners of Sony mirrorless cameras, the set is immediately relevant. TechRadar’s framing also points at Sony mirrorless users as the obvious audience. But the adapter package is what keeps the VP-1 from being a single-system bet.

On a multi-body shoot, that can matter more than another line in an MTF claim. One lens set moving between E, RF, Z, and L bodies reduces duplicate glass. It also keeps focus gear, matte boxes, and lens support setups more consistent if the housings match as stated.

Sirui says the VP-1 lenses use a uniform design across the series, allowing focal-length changes without repositioning lens accessories. The practical test is simple: check whether your follow focus, matte box, and lens support land in the same positions across the focal lengths you actually rent or own. Do not assume. Measure it on the rods.

Claimed optics need field verification

The optical construction is described as using aspherical elements and high-refractive-index glass. Sirui claims minimal chromatic aberration, low distortion, and low focus breathing. Those are useful claims, but they are still claims.

The checks are straightforward:

• Shoot high-contrast edges near frame corners for lateral chromatic aberration.
• Pan straight architectural lines across the 15mm frame for distortion behavior.
• Pull focus from near to far on all three lenses and watch framing shift.
• Test flare control against hard sources, since the lenses are said to use multilayer nano coating for flare suppression.
• Confirm the 270° focus throw is usable with your focus motor speed and hand-unit calibration.

The lenses also use stepless aperture and focus rings, with distance markings in both imperial and metric units. That is appropriate for cine operation. It does not guarantee repeatable marks under temperature change, adapter swaps, or rough handling. ACs should still build a witness-mark check into prep.

At $1,849 for the three-lens set, the VP-1 package is positioned as value glass for full-frame mirrorless cine work. The binary call is narrow: worth testing if you need manual full-frame primes across E, RF, Z, and L bodies; not an automatic buy until breathing, distortion, CA, and mechanical consistency are verified on your camera package.
