Re: Depth of Field Difference (m43 v DX) - An Example

So what was your point exactly, to demonstrate that at f2.8 you can't achieve sufficient seperation with m4/3 but at f1.8 it's close enough to DX so not worth mentioning?

I'm just asking because someone not familiar with m4/3 would simply get the impression you can't blur the backround with the smalle sensor m4/3 system.

As someone stated above, the old rules go out the window with m4/3.

The point was to illustrate that there is a difference.  I'm not making a value judgment about whether the difference is a positive or a negative.

Although, I haven't provided it here, the shot I took at f/2.0 on the OM-D is very close to the f/2.8 D200 shot.  If I think it's necessary for the case study, I may add it in, but right now it doesn't seem necessary for my purposes.  The rule of thumb that there is a 1-stop difference between m43 and DX seems to be pretty accurate from my test shots.
