Hi Pentaxclover et.al,
For thoses interested the direct link to this page is:
http://www.pictchallenge.com/diabolpif/invtest3.html
For translation try:
http://babel.altavista.com/translate.dyn
There is not much information on this page, not a very scientific approach of
measurement even though the image samples and analysis is posed as
such. I would also like to have seen a Pentax body used with mirror lock up,
an indication of how the lenses were focussed, film processing information
etc. I can understand why the test caused a quarrel.
Cheers,
Rob Studdert
