A few words on Equivalence and comparing systems

Perhaps the real question should be.....

Can you get the results you are looking for from the camera system you are using?

If you are a shallow DOF seeker, then FF is always going to be a better choice than M43.

If you routinely shoot in very dark environs with no flash, the high ISO performance of a good FF sensor is going to be better than M43.

If you want smaller, lighter lenses with a competent system, and the DOF differences are either an advantage (in the case of landscape and macro work), or not a significant factor in your style of shooting, then M43 is a remarkably adept option.

These are different tools.  Pick the one that works for your shooting style, or use both if needed. Don't try and make one into the other....just use the blasted cameras and if you find one does not do what you want in terms of DOF rendering, then realize you have to move to the other to get what you need out of it.

Until the laws of physics change, and you can get a FF sensor into an M43 body with M43 size lenses, then the compromises you make for portability are going to be in the DOF and sensor noise area.  As technology improves, the sensor noise issues are going to also continue to improve, so that may become a non-issue at some point, too (look how far we have come in terms of high ISO performance in the M43 in the past two years, for example.  I can now actually get good quality images at ISO 3200, and can relax about using ISO 1600 without having to worry about the color washing out or significant detail loss to noise...and future sensor performance will improve yet again on that.)

I frequently feel that this particular argument is perpetuated by non-M43 users who are trying to prove how INCOMPETENT M43 is to make themselves feel better about their own DSLR choices.  I often wonder what cameras the loudest equivalence complainers have....are they really FF users, or are they APS-C users trying to justify the small gains in DOF of their APS-C models over M43?  Perhaps the answer to these arguments should simply be: Why not try out the M43 cameras and lenses and see if they work for you?  No point in getting into this fray again and again.....
