7artisans 50mm T1.05 Vision Cine APS-C Lens for Leica L-Mount {82} Scale Feet, Meters

50mm T1.05 cine prime built for APS-C L-Mount shooters

The 7artisans 50mm T1.05 Vision Cine is a manual lens designed from the ground up for video work on APS-C L-Mount cameras. The T1.05 maximum aperture is a true transmission rating, not an f-stop approximation, which matters when you're matching exposure across a multi-lens cine kit. De-clicked aperture rings are the standard expectation on any serious video lens, and this one delivers that, letting you ride exposure during a take without audible clicks ruining your audio.

The 82mm front filter thread is large enough to accept standard matte box step-up rings, and the dual focus scale in both feet and meters means you can hand a focus chart to any AC regardless of their background. Manual focus is the only focus mode, which is exactly right for a lens positioned at this aperture on a video-first platform. At T1.05, shallow depth of field is aggressive on APS-C, so precise manual control is a feature, not a limitation.

For filmmakers building an affordable APS-C cine kit around the L-Mount ecosystem, this lens covers a natural 50mm perspective with specs that would cost considerably more from a traditional cine house.

Who It's For

Indie filmmakers shooting on APS-C L-Mount cameras who need a fast prime for low-light interiors will find the T1.05 aperture puts them in documentary and narrative territory without a cinema-house budget. Focus pullers and solo operators benefit from the dual feet-and-meters scale and de-clicked aperture ring, both of which are standard on professional sets. Videographers building a matched cine kit gain a consistent 82mm filter thread front element for shared matte box or filter systems across multiple lenses.

FAQ

Is this a true T-stop rating or an equivalent f-number?

T1.05 is a transmission rating, not an f-stop approximation. That matters when you're matching exposure across multiple cine lenses-you get actual light transmission, not theoretical aperture area.

Can you adjust aperture during a shot without noise?

Yes. The aperture ring is de-clicked, so you can ride exposure during a take without audible clicks bleeding into your audio.

What's the minimum focus distance?

The verified specifications don't include minimum focus distance. You'll want to confirm that directly with the manufacturer or retailer.

Does this lens work on full-frame L-Mount bodies like the Panasonic S5?

The specifications don't confirm the image circle size or compatibility behavior on full-frame L-Mount cameras. Check with 7artisans or your retailer for full-frame performance.

Why manual focus only?

On a cine lens at T1.05, manual focus is the right choice. Shallow depth of field on APS-C at this aperture means you need precise control, not autofocus hunting during takes.

Can I use standard matte box accessories?

The 82mm front filter thread accepts standard matte box step-up rings, so yes-it integrates into conventional video rigs without adapters.

Do I get focus distance marks for both imperial and metric?

The dual focus scale reads in both feet and meters, so your focus puller can work in whichever system they prefer.
