Before Canon redesigned their website, I did.

Now, as far as I know your best bet is to just Google images with the lens name and MTF.

Why? Food for thought, I guess. ... No MTF charts can be found on the web site, not even for recent lenses.

At this time I'm searching for all 8 18-55mm lenses. Because I'm writing an article about their quality. There are dependencies that I want to explain about the charts.

For new lenses the MTFs are there, they are just kind of hidden.

When the description of the lens comes up this is what you see.

At the end there is a small red read more.

When you click on 'read more' the sample picture and MTFs are there.

Note to the Moderators, it would be nice if the MTFs of old lenses were added to the Canon Camera Museum.
