Can anyone help with making a DOF adapter?
Well I'll be getting an HD camcorder soon. No high-end models that cost $ 1,000 and more, but most of the affordable at around $ 300 to $ 400. I'm more or less established in the purchase of Sanyo VPC HD camcorder resistant Water – WH1. Now I have a nikon d40x with 18-55mm lens. I would like to use this camcorder, because I want DOF with the focus ring. The manual focus button in these camcorders are very difficult to use because they tend to over do it since you have to hold it. How do you make a adapter for that? What I need to buy parts to create a homemade DOF adapter? Does the adapter work I do for my Nikon lens for any other camcorder (ie, Panasonic, Canon, etc)? Is there a high definition camcorder is better than for aroun $ 300 – $ 400?
Unless you find a high definition camcorder with interchangeable lenses, are not able to make her wear your Nikon system .. Not at any price is a modular video camera that you can use Nikon lenses. The Red One but is outside your budget at this time. Http://www.red.com/cameras/technology/ I fear that it may have to become a magician in the use of manual focus button in Sanyo.
