Pros & Cons
👍 Pros
- T1.5 maximum aperture allows excellent low-light performance and shallow depth of field for cinematic portrait and detail shots.
- Ultra-fast T1.5 aperture produces beautifully shallow depth of field and smooth bokeh for cinematic shots.
- Weather-sealed construction allows confident shooting in challenging outdoor conditions.
- Nine aperture blades produce smooth, rounded bokeh in out-of-focus areas.
- Weather-sealed construction protects the lens during outdoor and unpredictable shooting conditions.
- De-clicked aperture ring enables smooth, silent iris adjustments during video recording.
- 9 aperture blades create naturally rounded out-of-focus highlights.
- Geared focus and aperture rings are compatible with standard follow focus systems used in video production.
- Ultra multi-coated glass elements reduce flare and ghosting for cleaner image quality.
- 72mm filter thread is a common size, making it easy to share filters across multiple lenses.
👎 Cons
- Fully manual focus only, which requires more skill and time to nail critical sharpness, especially at wide apertures.
- Fully manual focus with no autofocus capability, which requires more skill and practice for fast-moving subjects.
- At 85mm on an MFT mount, the effective field of view is equivalent to 170mm, making it very tight for indoor or confined-space shooting.
- The 85mm focal length on an MFT sensor creates a very narrow 19.1-degree angle of view, limiting its versatility in tight spaces.
- Heavier and larger than typical MFT native lenses, which can affect gimbal balance on smaller camera setups.
- Heavier and larger than many native MFT lenses, which may affect gimbal balance on smaller rigs.
- No electronic communication with the camera body, so EXIF data and in-camera lens corrections are not available.
- No electronic communication with the camera body, so EXIF data like aperture and focal length is not recorded.
Frequently Asked Questions
Is this lens designed for photography or video?
It is a cine (cinema) lens, meaning it uses T-stops instead of f-stops, has a de-clicked aperture ring, and features geared focus and aperture rings optimized for smooth video operation. It can also be used for photography.
What camera mount does this Samyang 85mm cine lens use?
This version is built for Micro Four Thirds (MFT) mount cameras, such as those from Panasonic and Olympus.
Is this lens autofocus or manual focus?
It is a fully manual focus cine lens, designed for precise, smooth focus pulls during video recording.
What camera mount does this lens use?
This version uses the MFT (Micro Four Thirds) mount, compatible with cameras from Panasonic, Olympus/OM System, and Blackmagic Design that use the MFT system.
Does the lens have autofocus?
No, this is a fully manual focus lens. The focus ring is designed for smooth, precise adjustments suited to cinematic work.
What is the difference between T-stop and F-stop?
T-stop measures the actual amount of light transmitted through the lens, accounting for light loss in the glass elements. This makes T-stop ratings more accurate for video exposure than F-stop, which only measures the physical aperture opening.
Does the weather sealing protect against rain and dust?
The weather-sealed design helps protect against dust and light moisture, but it is not fully waterproof. Avoid prolonged exposure to heavy rain.
What is the equivalent focal length on an MFT camera?
On a Micro Four Thirds sensor with its 2x crop factor, this 85mm lens provides a field of view equivalent to approximately 170mm on a full-frame camera.
What filter size does it require?
It uses a 72mm front filter thread.
What filter size does this lens accept?
