I have an E-PL5 and I shoot with three fast primes 95% of the time. I tend to keep my aperture at f/4.5 or wider. I figure that I'm close to the sweet spot of these primes, and I am (I think!) avoiding any loss of sharpness due to the effects diffraction.

My question: Given the 4/3 sensor size and 16Mp density, when do we start to be diffraction limited in our efforts to find best sharpness in m4/3? I believe I'm correct that sensor size and megapixel count (therefore, pixel density) are the considering factors, but I'm unaware of the calculations and perceptual considerations.

Can anyone shed some light on this? I'll capture your response at 16 megapixels, f/4.5 to avoid any loss of detail

I'm very interested to know why do you relate diffraction to the sensor and pixels density.

Please educate me.

Diffraction becomes apparent when airy disk becomes larger than pixel size, no?

If you look 1:1. Otherwise pixel pitch doesn't matter.
