DVXUser forum member "teddybear" was kind enough to share a guide on how he made a gearless follow focus for his DSLR camera rig. It may be for a DSLR, but there is not reason why this would not work on a camcorder rig as well.
The Jag35SP that has been in development just got a new design...and it is small! Especially for a spinner. This seems like it might be another revolutionary product from the Jag35 folks. I'll keep you posted on updates and release date. - jag35.com
Jag35 is offering a special on a limited edition version of the Jag35ST static 35mm adapter only for the month of December. The adapter is being sold for the low (and I mean low) price of $69. A perfect adapter for beginner and indie film makers. Truly a great deal! Check it out here.
Recently announced is the D|Focus v2. Running around $120, the D|Focus is by far the more affordable and quality follow focus available. If you own v1 you also have the option to upgrade to v2. Perfect for film makers on a budget. For more info on the D|Focus visit dfocussystem.com.
