So, stop down to about f/8 and you will get a DOF of about 8-10 inches.

Now, you have to ask yourself why did you spend so much money for a f/1.8 lens when you really can't use it wide open for the types of photo's you want to shoot!

Yeah, thats what I am asking myself now

with lenses shot wide open (higher shutter speeds, lower ISO) the u 4/3 format is probably ideal.

No one forces one to shoot wide open. You know, it's perfectly fine to stop down. Typically the optical properties improve then too.

Except when you need the higher shutter speed.

Personally I would find m4/3 too limiting for portrait photography.

Why?

There is nothing ideal about m43 in this use case, far from it. Are you sure your personal attachement to m43-system is not clouding your judgement?

My personal attachment is absolutely clouding my judgment.   Portrait photography is exactly why I chose the 4/3 format.

Also, the sensor aspect ratio is a better match for printing than the 3/2 format so you aren't cropping so much.

Are you serious? 3:2 is very common ouput format, certainly more so than 4/3.

It is, but the 3:2 format doesn't match 8" x 10", 11" x 14", 5" x7" or 8.5" x 11" nearly as well as 4/3 does.  Those are common print sizes in the U.S.

With the camera you have, f/4 is about as wide open as you can go for a head and shoulders shot and your focus placement has to be perfect.

It is worse with FF if that is any consolation.

Lenses can be stopped down.

Unless you need the higher shutter speed.  If you want to shoot wide open portrait length lenses at base ISO, the 4/3 crop factor and aspect ratio is an advantage.

FF is no worse than APS-C

Mostly true.

or your belowed m43 for this kind of use.

Not true.  See above.
