follow focus

is anyone making any units for sale? Dan's only offering the ones he has to his mpic customers. I know some people were trying some DIY. I'd really like to buy one for a good price.

Working on one. Doing the research into the parts, trying to get the price down. Found another place yesterday to make the gearbox yesterday, going to see how it turns out. I will let you know.

Yeah, during the prototype stage and pre-production - the price is sky high because I am sourcing out material, building and rebuilding. Hopefully when all is said and done, it will be easy because everything will have been sourced and planned out. I am trying to keep this under $100 if I can, but I can't say for sure. Right now it has cost me about $150.00 for tests, tools, materials etc and that doesn't include my time!

Hello Andrew,

Have you seen the one on this website?
www.indifocus.com

Its design is a bit different, but the price is lower than some of the "name" ones.

for under $500 the micro looks really nice. I'll definately have to look at getting one once they're for sale.

Hi

I made my own follow focus for about 50$.

The most expensive part was the gear box. I first tried it with plastic bevel gears but they couldn't hold the torque. The one on the picture has metal gears.

The big plastic gear next to the lens might look stupid but that was necessary to keep around a 1:1 ratio. And I'm convinced it works as wel as a 500$ ff.

cheers

Hey Jelle,

Nice job. I was thinking about buying that gearbox, but it was alot more expensive on my end to get it - the gearbox alone was worth more than $50.00 when I researched prices. I noticed that you used the long rod for the actual turning part, pretty cool. I am making my own gearbox (no easy feat), so I am going to make the size alot smaller.

Oh yeah, can I see some stills of how you got the LCD on the shoe? Is that homemade or a purchased grip for the LCD?

Just finished my second generation prototype gearbox. Darn hard road. About a week, 6 hour days worth of work, and preproduction planning not included. Might end up being better just buying the darn thing, but haven't given up yet. A reliable source for aluminum boxes is had, just need a reliable source for bearings (certain type with housing) and I just might be on my way. If I can get all the parts and get this thing right, I can do it under $100 bucks.

Well the only hard thing to make would be the gearbox but you can just order that for 30 euros (shipping not included), so I don't know what else I should make for you :-) All parts can be ordered and can be very easily assembled. You need a rod support ofcourse. The most difficult part could be the gear which clamps over the lens itself. I found a gear with the right diameter in an old printer, cut out the inner plastic and voila. There no backlash when turning it because it's quite tight and the small teeth of the lens keep it into place.

I'll post some pics tonight when I'm home.
Good luck with your gearbox!
