Rokinon Cine DS100M-C 100mm
Delivering true 1:1 magnification at a 305mm minimum focus distance, this 100mm T3.1 prime captures life-size macro details on full-frame sensors while its cine-centric design features unified focus and aperture gears for consistent follow-focus swaps. The 9-blade diaphragm and Ultra Multi-Coated ED glass render smooth bokeh and suppress flare, with de-clicked aperture and dual-sided scales reinforcing its video-first ergonomics. This lens is best for macro videographers and filmmakers who need precise manual focus and accurate T-stop exposure for product cinematography or detailed nature footage.

Snapshot
The 30-Second Version
The Rokinon Cine DS 100mm T3.1 is a sharp, affordable full frame macro cine lens with true 1:1 magnification and smooth manual focus. Optical quality is well above average, but no autofocus, no stabilization, and weak bokeh hold it back. At $449, it's a great buy for tripod-based macro and budget cine work, just don't expect it to be a handheld all-rounder.

The proof
Performance
The 15 elements in 12 groups with one ED element and Ultra Multi-Coating do the heavy lifting. Sharpness is well above average, and the 1:1 reproduction ratio at a 305mm minimum focus distance gives you real working room for bugs, products, or detail shots. The 9-blade diaphragm should help bokeh, but our data shows it lands near the bottom at the 8th percentile, so don't expect creamy backgrounds to be its party trick. The T3.1 max aperture is also weak for a prime, sitting at the 5th percentile, which means low light shooters will need to crank ISO or add light. Manual focus is smooth and precise, which is exactly what you want for macro, but handheld focus pulling at 1:1 is a workout.

vs Competition
Stacked against the Tamron 28-300mm or Sigma 18-50mm f/2.8, the Rokinon is a completely different animal. Those zooms offer autofocus, stabilization, and versatility, but none of them touch 1:1 macro or cine-style manual control. The Panasonic Leica 12-35mm and Sony 18-135mm are better all-rounders for travel and everyday shooting, but they can't match the Rokinon's macro chops or its price for a dedicated cine prime. If you need one lens that does everything, look elsewhere. If you need a macro cine lens on a budget, this is the one.

Price
Value & Pricing
At $449 USD, this lens is a steal for what it does. You get full frame macro, cine-style controls, and genuinely good optics for less than half what a name brand cine macro prime would cost. The trade-off is build quality and the complete lack of autofocus or stabilization, but if you're shooting macro on a tripod or pulling focus manually on a rig, those don't matter much. For the money, it's hard to find this combination of magnification and image quality anywhere else.
Price History

Overview
The Rokinon Cine DS 100mm T3.1 is a manual focus macro lens aimed at filmmakers and photographers who want 1:1 magnification without spending a fortune. It covers full frame, has a de-clicked aperture, and uses standard cine gear positions so it drops right into a follow focus rig. Optical quality is the headline here, and our database backs that up with a strong 75th percentile ranking.
But this is not a grab-and-go lens. No autofocus, no stabilization, and a build quality score that lands in the bottom half of the pack. If you shoot handheld run-and-gun video, you'll feel every one of those 726 grams fighting you. If you work on sticks or a slider and want sharp macro shots with real character, this thing earns its keep.
Common Questions
Q: Does this lens have autofocus?
No, it's manual focus only. That's standard for cine lenses and actually preferred for precise macro work, but it makes handheld shooting much harder.
Q: Can I use this on an APS-C camera?
Yes, it covers full frame but works fine on APS-C with a 15.4 degree angle of view, which gives you an effective focal length around 150mm on most crop bodies.
Q: Is the aperture ring de-clicked?
Yes, the aperture control is de-clicked for smooth exposure changes during video, and it's calibrated in T-stops rather than f-stops for consistent light transmission.
Who Should Skip This
Skip this if you need autofocus or shoot a lot of handheld video. The lack of stabilization combined with the 726g weight makes run-and-gun work frustrating, and the weak bokeh and slow T3.1 max aperture will disappoint anyone chasing creamy backgrounds or low light performance. If you want a versatile travel or everyday zoom, the Sony 18-135mm or Sigma 18-50mm f/2.8 are much better fits.
Verdict
Buy this if you shoot macro or product work on a tripod, or if you're building a budget cine kit and want a 100mm prime with real close focus ability. The optical quality and value are the story here, and owners consistently praise both. Skip it if you need autofocus, stabilization, or a lens you can carry around all day without thinking about it.
