MTF is to lenses what frequency response is to amplifiers. The MTF rating is the spatial frequency at which the lens's contrast drops to 50%. The "catch" with MTF is that is a single frequency. It doesn't tell us how the lens behaves at higher and lower frequencies. < This message was delivered via the Olympus Mailing List > < For questions, mailto:owner-olympus@xxxxxxxxxxxxxxx > < Web Page: http://Zuiko.sls.bc.ca/swright/olympuslist.html > |
