Anyone who has done DSLR video knows how difficult it can be to focus manually. There are follow focus systems available but this is the first I've seen which actually uses the autofocus motor to give you manual focus via USB, it's a pretty revolutionary bit of kit for DSLR video shooters.

Thanks for this Chris I shall be ordering one of these next month
Here is another, been around for quite a while.
That one you link to Mike is $350, pretty expensive and doesn't look as good, but still great use of the tech. This week is first time I've heard of these! I wonder what uses they might have for stills photographers.
This is more interesting for stills - watch the video at the bottom:

I use software via laptop (Dragonframe) to control my Focus only and stepper motors to control Focus and Zoom for Time-lapse stills.
Hugo, I actually think I was the first person to post that video on ePz (when the software came out a year or two ago). It was also one of the reasons I bought an Android phone. Must have a look at Dragonframe Mike. If I get more serious with DSLR video I could see myself buying one of the V-controls above and integrating it with the rig.
Hi, Chris, it can get addictive like EPZ - building a 7 axes rig and controls currently.

I dug all my sons old scaleletric track out of the loft, then bought some good old fashioned Meccano to build a motorised truck than runs along the track, works like a dream
What sort of smoothness are you getting from the Scalextric Paul, also any video links? Those vids are impressive Mike, any pics of the setup?
This is the equivalent of EPZ for Time-laspe but non commercial.
Three iterations of Focus / Zoom in this post.

Images are Focus01 and Focus02, just below the third video frame for the DC motor set up
Showing a 3 axes set up, did not a take any stills of the five axes set up.
That's a fab looking slider, expensive?

Yeh very smooth and the power comes from the track so no trailing wires, speeds adjustable as well using an old scaleletric trigger.
No video links as yet.

Slider: http://www.dynamicperception.com/ Stage Zero with DC motor or Stepper motor option now. I modified mine to take the stepper as there was no option when I purchased mine a couple of years ago.
