I apologize for the confusion - it is indeed Chinese, and here is the translation a kind soul sent it to me off-list. Thank you, Oh Cheng Yu.

You may post my reply on the list. Pentax AF 50/1.4 High contrast: The optimum aperture appears to be between f/4 and f/5.6, with a large difference in resolving power between the centre and edges, at f/2.8 the difference beween the centre and edge is 30 lpm; at f/1.4 the resolving powers at the centre and edge are 88/77 lpm respectively. Low contrast: There is a larger range of optimum apertures from f/4 to f/11, there is a larger difference between centre and edge (comment: from right graph, seems to be the opposite). Conclusion: Possess high resolving power, but has unequal treatment of centre and edge. Pentax AF 50/1.7 High contrast: Highest resolving power of 122 lpm occurs at f/8, but there is a larger difference between centre and edge (comment: does not seem so from left graph); Low contrast: Optimum aperture is between f/8 and f/11 with 90 lpm. Conclusion: Unequal treatment of centre and edge. Regards, Oh Cheng Yu Singapore " Alan wrote: AC> Many sites from mainland China are slow indeed. That is AC> Simplified Chinese btw, not Japanese.
