Originally posted by talgarik Is it supposed to be a joke? I was only stating the obvious: the f number in a MFT system will give you the same results than with any other system in terms of exposure, but in terms of DOF even if you buy an expensive Leica 25mm 1.4 in DOF terms you get a 2.8 performance, that's not an opinion, that's a fact. For some people it can be fine, but when you are into a thread sharing information, it has to be mentioned. Of course then you can play with the distance between main subject and foreground to obtain a kind of bokeh effect, but the technical limitation remains.
Is that supposed to be a joke? Because what you stated is quite simply factually incorrect. You do NOT lose TOTAL control of DoF. That could only happen if you had access to only on aperture, like an old Brownie or something like that. In M4/3, you in fact, CAN control your DoF. It might not be as shallow due to physics and the sensor size but it is controllable.
I am a M4/3 shooter and do not find myself wishing I was still in the Pentax APS-C world. Yeah, I lose a little bit of dynamic range and apparently (but not really) DoF but the size, weight, and interface advantages make it a better system for me.
This Is wide open on the Olympus 45/ 1.8. I find it acceptable.
And here is a shot at 4.5 on the same lens. They totally look the same, dont they
If the KP had the abilities that Olympus offers in its mirrorless system, I would have bought it. In fact, I ordered one from B&H and returned it as it was not at all what I was hoping it would be. A mirrorless system offers flexibility that a DSLR cannot. And I like that.
