This is not intended to knock M43 and is not intended to start a DSLR vs M43 argument, but....

I am really interested in whether I can achieve the type of shallow DoF/subject isolation/3d effect automative photos that I like without adding a fake PS background blur.

A quick google images example (not sure what camera/lens this was with):



I own 20mm and 14mm Panasonic primes for m43 and have access to (through work) a D800 with 50mm f1.8 and 85mm 1.4 and a 5D2 with the 24-105 f4 lens so know what FF can do.

I assume I'd need to buy a lens as not really succeeded with the 14 or 20 primes - can a Pan 42.5mm or Oly 75mm achieve the same results? Or even the 35-100 2.8 Pan?

Ok some quick and completely un-scientific tests with a small selection of the lenses I had to hand... oh, and sorry the car is dirty :(

So what does any of that prove? no idea :confused:

It didn't help that I wasn't really comparing like for like - ideally would have tested with the 42.5mm f1.2 or the 45mm f1.8 against the 85mm Nikon, but I don't own either of those - yet!

On another forum I learnt that if I am comparing say the Nikon 85mm f1.4 with M43, I would need a 42.5mm f0.7 to achieve equivalent background blur. Or the Nikon 50mm f1.8 I would need a 25mm f0.95.

Voightlander has some f0.95 lenses for mft.

Or borrow a Pana 42.5 or Oly 45 or 75 and try them; they won't have as much blur as FF, but they may well be satisfactory.

as for a native lens, the 75mm 1.8 MIGHT be close... but the reference image has alot of background compression, probably a 200 f/2 or somewhere close to the focal length.. just my guess.. but you never know, could be a 85 1.2 canon :biggrin:

Nikon 85mm F1.4used in conjunction with Metabones speedbooster nets ~60mm F1.2 which renders fairly well. When I get home I'll post some shots for kicks.
The 50mm /1.4 I was using today on a RJ focal converter is a cheaper option that also works pretty well. Due to the bright sunshine though I had to shut down the aperture somewhat even with a CPL mounted my G5 couldn't handle the light.
