Can I use the ExpoAperture guide with my digital camera which has a 1.6 equivalent focal length?
Yes. Many of the digital SLR cameras on the market today have either a 1.5 or 1.6 equivalent focal length. Taking this into consideration we have developed a Focal Length Conversion Table that will convert the actual focal length of your lens to one that will result in the correct depth of field when set on the Guide’s dial. Do not confuse the converted focal length with the equivalent focal length, they are not the same. Here’s how – Refer to the Focal Length Conversion Table and determine the actual focal length of the lens you are using and set the ExpoAperture guide to the corresponding focal length in the table. Values that are not directly listed in the table can be approximated.
