Mitakon Zhongyi Speedmaster 50mm f/0.95 III 50mm
Its f/0.95 maximum aperture on a full-frame Leica L mount enables extreme light gathering and razor-thin depth of field with 9 rounded aperture blades for circular bokeh. The all-metal construction and long-throw manual focus ring provide tactile precision for deliberate composition, while the optical design with 2 ED elements maintains sharpness wide open. This lens is best for portrait photographers using Leica L-mount cameras who want f/0.95 isolation and a signature bokeh look without autofocus reliance.
Snapshot
The 30-Second Version
The Mitakon Speedmaster 50mm f/0.95 Mark III brings near-Noctilux bokeh and light-gathering ability to L-mount for under $700. Center sharpness is solid, and the rendering is wonderfully dreamy, but soft corners, flaring, and manual focus only mean it's best suited for deliberate portrait and video work. If you can live without autofocus, it's the cheapest way to explore f/0.95 creativity.
Pros & Cons
Pros
- Insane f/0.95 aperture lets you shoot in near darkness and obliterate backgrounds
- Creamy, circular bokeh with excellent subject separation
- Smooth, well-damped manual focus ring and a de-clicked aperture for video
- Relatively compact for a lens this fast
- Huge value compared to Leica's own f/0.95 options
Cons
- Soft corners wide open that never fully sharpen up across the frame
- Prone to flaring and ghosting with strong light sources
- No autofocus, which renders it a pain for fast-moving subjects
- Heavy at 620g for a manual 50mm prime
- No weather sealing, so it's not your best friend in rain or dust

The proof
Performance
The headline number is the aperture, and it's no marketing gimmick. In our lens database, this f/0.95 monster sits at the very top, outperforming nearly every lens we have records for in terms of pure light gathering. Wide open, you can shoot handheld in dimly lit rooms at base ISO and still freeze motion. The bokeh, shaped by those nine rounded blades, is dreamy and soft, with the kind of swirl and character that modern sharpness-obsessed lenses often lack. It's not clinical perfection, and that's precisely the point.
Optical quality, however, is a mixed bag. Center sharpness at f/0.95 is respectable and a clear step above the previous generation of ultra-fast Chinese lenses, but edges soften noticeably and never fully recover even when stopped down to f/2.8. Flaring and ghosting can be intrusive against strong backlight, so a hood is a solid idea. There's some chromatic aberration, though the five ED elements do a decent job of keeping purple fringing under control. Real-world use rewards photographers who embrace the dreamy look, but if you need precise corner-to-corner detail for landscapes or flat art reproduction, this lens will frustrate you.

vs Competition
The most direct same-bracket rival is the TTArtisan 50mm f/0.95 for L-mount, which sells in a similar price range. Both are manual focus, heavy, and produce dreamy bokeh, but the Mitakon has a slight edge in center sharpness based on our testing, while the TTArtisan sometimes ekes out slightly better build and flare control. The 7Artisans 50mm f/1.1 is another budget alternative, but you lose two-thirds of a stop of light, and the Mitakon's bokeh is noticeably creamier.
If autofocus is non-negotiable, you'll need to give up some speed. The Sigma 50mm f/1.4 DG DN Art is a stellar autofocus lens that's razor-sharp across the frame at f/1.4, and it sells for around $849. It's much more versatile for events or walkaround use, but the creative possibilities of f/0.95 are on a different planet. For video shooters who want a de-clicked aperture and a vintage rendering, the Mitakon still feels more like a cinematic tool than any modern autofocus prime.

Price
Value & Pricing
At $499 to $682, the Speedmaster is an absurdly affordable ticket to the f/0.95 club. When you consider that Leica's own 50mm Noctilux-M f/0.95 costs over $10,000, the value proposition becomes obvious. Yes, you sacrifice build quality, weather sealing, and Leica's pixel-peeping sharpness, but you also keep over nine grand in your pocket. Adorama currently lists it at the cheapest end of the range, so if you're set on this lens, that's the place to grab it. For anyone who's always lusted after that razor-thin depth of field look but thought it was reserved for trust fund kids, the Mitakon makes it accessible.

Overview
Photographers who chase shallow depth of field and low-light magic, listen up. The Mitakon Zhongyi Speedmaster 50mm f/0.95 Mark III is a full-frame prime that stuffs one of the widest apertures we've ever tested into a relatively compact L-mount barrel. This is a lens designed to make backgrounds melt, to turn nighttime streetlamps into soft globes of light, and to separate a subject like a razor cutout. It's manual focus only, no stabilization, and it tips the scales at 620g, so it's not a casual 'bring everywhere' lens. But if you shoot portraits, creative stills, or video with a cinematic bent, this thing is a seriously tempting tool.
We've seen plenty of fast 50s, but the Speedmaster slots into a rare category. At f/0.95 it collects over twice as much light as an f/1.4 lens, letting you shoot in near darkness while keeping ISO noise low. The nine-blade aperture produces circular bokeh highlights that our database ranks among the best on the market. It's not a flawless optical performer across the frame, but the center sharpness wide open is perfectly usable, and the way it renders out-of-focus areas is genuinely seductive.
Available in several mounts, including this L-mount version for Leica SL and Panasonic S cameras, the Mark III retails between $499 and $682 depending on the store. Adorama currently sits at the low end, making it one of the cheapest ways to get that 'Noctilux look' without the four-figure price tag. We've crunched the numbers and dug into the feedback, and here's how the Speedmaster really stacks up.
Common Questions
Q: What's the T-stop of this lens?
Mitakon doesn't publish a T-stop value, just the f/0.95 geometric aperture. In real-world use, light transmission is slightly lower due to glass absorption, likely around T1.1 to T1.2, which is still exceptionally bright. You'll comfortably shoot in candlelit scenes without cranking ISO.
Q: Does this lens transmit EXIF data to the camera?
Yes, the L-mount version passes EXIF information like focal length and aperture to your Leica SL or Panasonic S body. This means lens corrections can be applied automatically and the metadata will be embedded in your files, which is helpful for cataloging.
Q: Will it work natively on my Panasonic S5?
Absolutely. The lens uses the L-mount standard and mounts directly onto any L-mount camera, including the Panasonic S5, S1, and Leica SL series, without an adapter. Just twist it on and you're good to go.
Q: Is the lens weather sealed?
No, there's no gasket or seal anywhere on the barrel. Avoid using it in heavy rain, blowing sand, or dusty environments, as moisture and particles can work their way into the mechanics or the sensor area.
Who Should Skip This
If you shoot fast-paced events, street candids, or anything where autofocus is crucial, the Speedmaster will slow you down and cost you shots. Wedding photographers who need to react instantly should invest in an AF lens like the Sigma 50mm f/1.4 Art instead. Landscape shooters who prize corner-to-corner sharpness even at wide apertures will also be disappointed, the Mitakon is about dreamy character, not perfection. And if a lightweight, weather-sealed travel lens is your priority, look at the Panasonic Lumix S 50mm f/1.8 instead, it's half the weight, fully sealed, and a fraction of the cost.
Verdict
This lens is a portrait artist's best friend. If you thrive on manual focus, love the tactile process of nailing focus at f/0.95, and want bokeh that looks like brushed velvet, the Speedmaster is a no-brainer at this price. It rewards patience and a steady hand, and the results can look like they were pulled from a high-end cinema lens. Video shooters on Panasonic S cameras will also appreciate the stepless aperture ring and the sheer light-gathering ability for run-and-gun night scenes.
But it's not a one-lens-fits-all solution. If you need autofocus for quick candids, event work, or chasing kids around, look elsewhere. If you're a landscape photographer who demands sharpness to the corners, you'll be pulling your hair out. And if you plan to shoot in rough weather or dusty environments, the lack of sealing is a real drawback. For that crowd, a Panasonic 50mm f/1.8 or Sigma 50mm f/1.4 Art makes way more sense.
