Re: MFT 25mm f/1.4 fails to blur background like Full Frame 50mm lens @ f/2.8

Can you do us a favour and shoot equivalent photos.

eg: Oly

25mm, f1.4, iso 200

D700

50mm, d2.8, ISO 800.

Those two photos should end up the same.

Just a hunch but I'm wondering if using ISO 4 stops above the Oly is accentuating the background blur due to increased noise.

Also, make absolutely certain focus is nailed on the microphone.
