I was researching to buy a light combo for doing portraits and I enjoyed using GM1 with Olympus 45mm but I know the bokeh of Sony 50mm is better. The question now is when compared to Oly 75mm, which has more bokeh between these two cameras:

Any M43 camera with Olympus 75mm F1.8

versus

Any Emount APSC with Sony 50mm F1.8

COnsidering the effective aperture calculation for both?

I read that you can compare the background blurriness by dividing the focal length and the aperture.

So the Olympus combo will yield a ratio of ~42 and the Sony combo will yield ~28. That's a lot!

But they are from different systems, so if I will use their effective apperture..

Olympus 75mm will have 21[75/(1.8x2)] and SEL50 will have 18[50/(1.8x1.5)].

Then they are almost the same! WIth the sony combo, I dont need to be much farther to the subject and the body+lens combo is lighter. (Of course, I would be needing a good IBIS body like GX7, EM5, EM1, EPM2 etc and not GM1/GM5)

I tuned in to watch Broadchurch the other night and had to turn off after five minutes. Nearly every shot consisted of the actors appearing to float against a completely blurred background. The "effect" was ridiculous. It looked like a DPR obsessed graduate had been let loose and had been indoctrinated into believing that this was artistic. Kubrick would be weeping.

I felt the same way about Virunga. Beautiful movie, but shot entirely on Canon FF, and there were times when the thin DOF was really distracting.

Please, people! Learn about composition, and getting the most out of your DOF! This isn't a case of you can never be too rich or too thin.
