Lens Whacking Tips & Tricks
- Use Older Manual Focus Lenses – While I would not recommend going out and getting a manual focus lens specifically for lens whacking i would say that if you have one, specifically one with an aperture ring, it would be very preferable to most newer lenses.
- Open Your Lens to its Maximum Aperture and Set Focus to Infinity – For the best results your lens much be set at its maximum aperture (example: F/1.8), and be set to focus to infinity.
- Hold Your Camera To Your Chest -Due to the nature of not having your lens fixed toy our camera it is very easy to ruin a good shot via unwanted movement. Securing your camera to your chest helps to stabilize your body and prevent unwanted issues in your lens whacking video.
