The focus shifter — which, for now, is also going by the name “lens shifter” — is a simple, lens-mounted, adjustable follow focus that works by attaching to the focus ring on lenses between 56 and 98mm in diameter. Using the attachable marker board you can then mark your focus and transition points in advance, shifting between them with ease when the time comes.
Here’s the Kickstarter video by creators Daniel Bauen and Jake Snowden for those of you who want a little bit more information:
If you like what you see and you want to support these guys in making the focus/lens shifter a reality you can head over to their Kickstarter page and fork over at least $45 towards the name of your choice. At the rate the project is growing in popularity we’re fairly certain they’ll reach full funding soon; the only question left at that point will be whether the final product will be called the focus shifter or the lens shifter…
