Pros & Cons
👍 Pros
- T1.5 maximum aperture provides excellent low-light performance and shallow depth of field control.
- Unified gear positions across the Cine DS line allow fast lens changes on a follow focus system without reconfiguration.
- Dual focusing scales on both sides of the barrel let the camera operator or focus puller read distance from either side of the rig.
- Color-matched across the Cine DS series for consistent look when cutting between multiple focal lengths.
- 8-blade iris produces smooth, rounded bokeh in out-of-focus areas.
👎 Cons
- Fully manual focus and aperture with no electronic communication to the camera body, so no autofocus or EXIF data is recorded.
- At 85mm on a 2x crop MFT sensor the effective 170mm field of view is very narrow, limiting versatility for wider shots.
- The all-metal and glass construction adds considerable weight and size compared to native MFT autofocus lenses.
- No weather sealing makes it vulnerable to dust and moisture in outdoor shooting environments.
- Lacks image stabilization, which is particularly noticeable at the long effective focal length on handheld MFT rigs.
