I switched the focusing screen of my Canon EOS 1D Mark III in order to make it easier to focus manually. I have used various manual focus lenses and all the help for that is welcome. The Canon Ec-S fosucing screen makes it a little easier to use manual focusing. The con is that it makes the viewfinder darker. Changing the screen was easy (clear instructions were provided) and currently keep Canon Ec-S screen on all the time instead of the standard screen. text/html 2023-02-22T22:37:31+00:00 Anonymous (anonymous@undisclosed.example.com) https://heikkisiltala.net/wiki/en/information_technology/cognos_bi?rev=1677105451&do=diff The automatic IBM Cognos BI Motto: Run your Business Intelligence, don't let your Business Intelligence run you!
