Greetings,

Here are some charts that display the lens focal length versus diagonal angle of view (AOV) for the 4/3rds system. Thanks go to "acme" for creating the first chart shown below. It is a 900 pixel wide 72 dpi JPEG.

The next chart was created by me. It follows the general form of similar charts from Olympus. It is available in two versions. The first is a 1200 pixel tall 150 dpi JPEG.

The second is a PDF version which you can download. It is a vector version which can be scaled to very large sizes without the dreaded pixel "jaggies". It is the best-looking version and you'll need Adobe Reader (or compatible) to view it.


Finally, thanks go to Jens (jebir) for posting the original thread about these charts.
