The next time you watch a great film, look out for things beautifully falling in and out of focus as the camera moves past. This is done with a focus slider and these cost hundreds of pounds to buy.
Today, I’m going to share with you my awesome focus slider which will cost you very little to make and will give your videos a really professional feel.
The video below will show you a bit of the build process, but mainly the effect using the DIY focus slider.
My slider consists of three main parts:
a) A bracket to mount the camera on which is attached to b) Two sliding guide rails from a set of drawers which is mounted on c) a stand
It works by smoothly sliding the camera with a set focus past a stationary object and the draw sliders do this wonderfully.
My version is designed to be used from a table top, hence is mounted to a mental stand from a DIY store, but you could think about mounting in another way between to tripods for example.
Let’s look at each section separately:
a) A bracket to mount the camera on
I used an upside down U shaped bracket from my local iron monger which did require drilling, etc.
Why not use a cheap bracket like this turn up side down, to joint the two draw sliders to save time?
b) Two Telescopic drawer rails from a set of drawers
These are available from DIY stores or any set of drawers which have seen better days.
The length you will need depends on you subject, I used 2 foot long rails myself.
These rails will by used on their side and will be pre-drilled where they were mounted to both drawer and carcass.
We can utilise these holes to save work.
c) The stand
Again I used a stand that I found from the iron mongers, but you can bolt it to anything really.
Why not buy three of the below brackets, two mount the rails to two tripods and one to join the brackets as already suggested?
For best results use a small aperture and you’ll find that the effect is stronger the closer you are to the object.
