Q: Where can I purchase a D|Focus?
A:  You can now purchase all D|Focus products on our website or from any of our Authorized Dealers listed on our website.

Q: Do you sell rail mount systems?
A: Yes! We sell 3 different Bundle Packages featuring rail mount systems.  We also sell 3 different Shoulder Rig Bundle Packages.

Q:  Will the D|Focus work with The Canon 5D Mark II, Canon 7D, Nikon D90 or Panasonic Lumix GH1?
A: The D|Focus mounts to standard 15 mm rods, so pretty much any camera you can mount on 15 mm rods can be used with the D|Focus. Also with the new D|Mount, the D|Focus can be configured with any DSLR without a rail system!

Q: What will I need for a complete Follow Focus system on a Canon 5D Mark II, Canon 7D, Nikon D90 or Panasonic Lumix GH1?
A: You will need the D|Focus, at least one D|Gear and either a rail system or the D|Mount.

Q:  What size lens gear do I need for my lens?
A: The D|Gears come with 4 size legs to fit almost any lens. It's a one size fits all solution!

Q:  Will the D|Focus work with the Shrigg?
A:  Yes!

Q: Why is the D|Fcous offered without a lens gear?
A: Some users may wish to use the D|Focus with a 3rd party lens gear. The D|Focus will work with any industry standard 32 pitch (0.8) mod lens gear.

Q: I am hearing a lot of noise from the gears in my audio.  What can I do to fix this?
A: The best thing to do is use an external microphone not attached to the camera itself.  It’s not so much the noise the gears make that you are hearing but the vibration.  If you must use the on board microphone or have your microphone attached to the camera, try to use smooth slow focus pulls. 

Q: Does the D|Focus support speed cranks or whips?
A: Yes! This is now a standard feature!

Q: Where is the D|Focus manufactured?
A: Upland California, USA

Q: Do you ship internationally?
A: Yes, however there will be an additional charge for international shipping. Also, shipping to some countries can take a considerable amount of time (up to 3 weeks in some cases.) Please take this in to account when ordering.

Q: Do you offer some kind of a warranty?
A: All D|Focus products come with a one year limited warranty.

Q: How long will it take for me to receive my D|Focus Order?
A: We usually have all of our products in stock and ready to ship on a daily basis.  Our Authorized Dealers throughout the world are also well stocked and ready to ship your order.

Q: Why are the miter gears exposed instead of being enclosed in a gearbox?  Doesn’t this put the gears at risk of being damaged or getting jammed?
A: Having the miter gears exposed makes the D|Focus much easier to build and thus less expensive for you.  Traditional gearboxes are typically designed to turn high RPMs, pull lots of torque and run for extended periods of time.  This isn’t the case most of the time when filming.  You will probably be doing slow, smooth focus pulls most of the time.  A gear”box” isn’t necessary; a gear”plate” is used instead.

Q: Is there any “play” or “slop” of "backlash" in the gearplate?
A: Not much. The new D|Focus V3 allows the user to adjust the tension in the gearing. This can, in most cases, eliminate most of the backlash! This is a unique feature usually only found on follow focuses costing $1000 or more!

Q: Are replacement parts available?
A: Yes.  Please email for price and availability.
