Mitakon Zhongyi Speedmaster 20mm f/0.95 Review
The Mitakon Zhongyi Speedmaster 20mm f/0.95 offers an almost magical aperture for low-light shooting, but its manual focus design makes it a tool for specialists, not everyone.
The 30-Second Version
The Mitakon Zhongyi Speedmaster 20mm f/0.95 is a specialized, manual-focus prime for Canon APS-C cameras. Its massive f/0.95 aperture is incredible for low-light and bokeh, but you sacrifice autofocus, stabilization, and portability. It's a unique tool for astro and creative photography, not an everyday lens.
Overview
If you're shooting on a Canon APS-C mirrorless camera and you've been hunting for a lens that can see in the dark, the Mitakon Zhongyi Speedmaster 20mm f/0.95 is a fascinating option. It's a manual focus prime lens that gives you a 30mm full-frame equivalent field of view, but the real headline is that massive f/0.95 aperture. For around $369, you're buying a tool specifically for low-light photography and extreme background blur. It's not a walk-around lens; it's a specialized instrument for when you need to gather every last photon.
Performance
Our data puts this lens's aperture performance in the 99th percentile, which is no surprise given the f/0.95 spec. In practice, that means you can shoot handheld in near-darkness at lower ISOs than with any kit lens. The bokeh quality scores in the 98th percentile, and with nine aperture blades, out-of-focus highlights are rendered smoothly. Optical sharpness lands in a respectable 78th percentile, meaning it's decently sharp, especially when stopped down a bit from wide open. Just remember, there's no autofocus or stabilization here, so your technique needs to be on point.
Pros & Cons
Pros
- Extremely bright f/0.95 aperture for incredible low-light performance. 99th

Value & Pricing
At $369, the Speedmaster 20mm f/0.95 sits in a weird and wonderful niche. You won't find another lens with this aperture for Canon RF APS-C at this price. The trade-off is giving up autofocus and portability. If you need AF, you'd look at something like the Canon RF 16mm f/2.8, but you'd lose over two stops of light. This lens is all about trading convenience for pure light-gathering capability.
vs Competition
This lens doesn't have direct competitors because of its unique aperture, but it fights for attention in your bag. Against the versatile Tamron 17-70mm f/2.8 zoom, you lose range, autofocus, and stabilization, but you gain over three stops of light. Compared to a compact prime like the Viltrox 35mm f/1.7, the Mitakon is wider, much faster, but also heavier and manual-only. For astrophotography or creative portraits where light is everything, the Mitakon wins. For general travel or video where you need AF, the others are better picks.

Common Questions
Q: Is the Mitakon 20mm f/0.95 good for astrophotography?
Yes, it's excellent for astrophotography. The f/0.95 aperture lets you capture more stars and nebulae with lower ISO or shorter exposures than almost any other lens for Canon APS-C cameras, though you'll need a sturdy tripod since it has no stabilization.
Q: Can I use this lens on a full-frame Canon R camera?
Technically, it will mount, but it's designed for APS-C sensors. On a full-frame body, it will show severe vignetting (dark corners) because the image circle isn't large enough to cover the entire sensor.
Q: How hard is it to focus manually with an f/0.95 lens?
It's challenging. The depth of field at f/0.95 is razor-thin, so precise focus is critical. Use your camera's focus peaking and magnification aids. It's not ideal for fast action, but it's manageable for static subjects or planned shots.
Q: What's the image quality like wide open at f/0.95?
It's decent. You can expect some softness and chromatic aberration at f/0.95, which is common for such fast lenses. Stopping down to f/1.4 or f/2 significantly improves sharpness and contrast across the frame.
Who Should Skip This
Skip this lens if you shoot video, vlog, or anything that requires reliable autofocus. Travel photographers will find it too heavy and specialized. If you're a beginner or just want a sharp, easy-to-use lens for everyday shots, a standard autofocus prime or zoom is a much better choice. For those needs, look at the Canon RF 16mm f/2.8 or the Tamron 17-70mm f/2.8.
Verdict
Should you buy the Mitakon Zhongyi Speedmaster 20mm f/0.95? Only if you know exactly why you need it. This isn't a lens for beginners or for casual shooting. It's for the photographer who stares at the Milky Way and needs a faster lens, or the creative portrait shooter who wants surreal background separation from a wide angle. If you're willing to work with manual focus and carry the weight, it unlocks shots that are simply impossible with other RF-S lenses. If you need autofocus for anything, look elsewhere immediately.
