Pentax SMC FA 35mm 3.5 IF lens MTF chart


I know that Pentax does not provide any MTF charts. However, I have seen some floating around the web for other 645 Pentax lenses.

There has to be one for the Pentax SMC FA 35mm 3.5 IF lens. Can anyone help me out.

I know there are a ton of people who would like to see this chart as well; now that the 645D is available.

Please let me know where I can find the MTF chart for this lens.

No; Because he does not take "Field Curvature" into account.

So, It is not an accurate representation. An MTF will give a better interpretation and show "Field Curvature" as well.

Thank you
