Open Source Arduino Follow Focus
Requires power - plus program port, unless it can be integrated into Operating System with selectable USB plugin switch.
Two Versions
- IBF (Integrated Beta Front Mount)
- IMFF (Individual Module) (i.e. box with connection or battery DIY option) (link soon)
Features for it, may create separate list or project board if valuable.
Features for both
- Motorized Option
- Non Motorized (depends on camera and lens)
- Lanc converter ( programmable to accept lanc signals and output different ones for expanded camera and accessory compatibility)
- Saved presets for individual lenses or for rack focus on the fly
- Auto lens based adjustment
- Auto Lens boundary detection for unknown lenses
- Auto
- Buttons - standard lanc
- start/stop
- record
- zoom (lens dependant)
- focus
- aperture (if wanted)//
- Brushless Motor integration for cinema lenses
- Variable Speeds for Brushless motor
- Motor Calibration for tighter or looser lenses
- Optional combination laser and sonar based rangefinding (an idea)
- Ability to display on IMFF LCD and IBF
- Can be used for mechanical AF center focus.
- Expandability for specialty lenses.
- Dual Focus needs for Anamorphic
- Telescopic lenses.
- Aperture and focus control
- Non standard cinema lenses i.e. a motorized fix for lenses whos focus changes when zooming i.e. cheaper lenses.
Seperate Features
IMFF
- LCD Module integration
- Standard 15mm rod clamp for lens gears. (link soon)
IBF
- Beta Programming link / setup utility / onboard tweaking and presets (more on this)
- Integrated lens presets both manual, downloadable and custom save
- Saved presets for individual lenses or for rack focus on the fly
- Perhaps an api for additional arduino or shield integration if the user wishes, not sure might be better for Gamma and a back module at that point.
