USAF target photographed at a distance of 55 times the focal length of the SMC FA 1.4/50mm: 2,75m. http://gallery37564.fotopic.net/p8778138.html
I can't seem to figure out how to convert UASF target photographs to lpm. All the different explanations rather confuse than help me. Perhaps Rob or others can explain how the read and covert the results, P l e a s e ? Iknow this is digital and not film. I used 55 times distance. Perhaps this shoul be multiplie by the crop factor 1.55? Neverthe less, it seems to me the resolution is quite poor compared to negs. According to tsts done by others this lens i able to resolve up to 98 lpm. Is there a better way to test lenses using a digtal camera. I could of course test the lens on film...:-( But I still haave to get it - how to read and convert the groups and elements.
