Tell me something I don't know.

I've posted this information and graph for people myself.
I use both 4:3 and micro 4:3 cameras and have for many years.
You often refer to Micro 4:3 as "dSLR like", and myself and other 4:3 users have pointed out to you that dSLRs come in the 4:3 standard as well, the "SLR" part referring to the mirror mechanism. These types of dSLRS - and their mirrorless counterparts - use the 4:3 sensor format (isn't that what I said ??) and not APS-C. Do not mistake my uncaring attitude about specs as unknowing. I have explained 4:3 terminology to you in the past when you've referred to micro 4:3 as having "micro 4:3 sensors", which, as I've explained above, is incorrect.
The "compact camera" description I don't agree with at all, as mirrorless are anything but. They are still quite large, come with a lot of equipment and lenses, and pretty much require a bag to carry around. (Although I have stuck my PEN in my purse many times.)
I still say, havoc, that you should try one sometime. You might be surprised.
