Hi folks

Ive had this lens for a few months attached to my EOS 90D. Happy with results so far. But my question is how to use and get the benefits of the small information screen on the lens. Any useful advice on using this screen to improve my photos will be well recieved.

Thanks

Ramsden

Refer to pages 13 to 17 in the User Manual for details. One usage is for focus distance and depth of field which can be very handy.

e.g. your subject is say around 10 feet and you have the aperture set to a particular value. After focusing, you can see the actual distance along with depth of field. You can then adjust the aperture to get either more or less depth of field depending upon what you want to achieve.
