I tried to do a more careful calculation on the difference between 15MP and 18MP, but it is harder than I thought. If my new calculation is right, then it's smaller than 1/7th of a stop difference. Not significant at all.

Not exact at all, but roughly speaking it looks like a factor of two of MP in a fixed sensor size will change the diffraction limit one stop.

Hi Popo,

I found your great pictures explaining DoF and diffraction, can I use these pictures in my slides to explain the effect of different aperture sizes?

Thank you!

Best regards,
Albus
