Firmware Update for 7D

[trb01]

Is it necessary to update firmware?  I'm 'tech challenged' and not clear on how to do it.

Welcome trb01!

Its not "mandatory" persay, but there are some key features that you might like: http://www.usa.canon.com/cusa/consumer/standard_display/EOS7D_firmware_features

If you download the firmware, I believe there will be instructions on what to do depending on what operating system you are using: http://www.usa.canon.com/cusa/consumer/products/cameras/slr_cameras/eos_7d#DriversAndSoftware
