. What's new?
  • You can configure 2 custom film sizes. Great for professional digital camera users. Just enter the dimensions of the CCD chip, and you can calculate hyperfocal distance, depth of field, etc.
  • The depth of field calculators can now use two circle of confusion values: one calculated from the Zeiss formula, and one called 'optimal' that most books tend to use. Choose the one that best fits your needs.
  • New functions: angle of view calculator, bellows factor calculator, EV calculator.
  • Support to run from drive E: has been added (netBook, Series 7).
  • Bug fixes and optimisations in the EV difference and various Flash calculators.
