I don't really have that many lenses, at least compared to a lot of you here. I believe I only have 7 true m43 lenses and one of those is the 9mm fisheye BCL.
So I do have more than 3, but it is a rare outing if I leave the house with any more than one or three. The only exception would be when traveling I might have a couple more than 3 but the intent is that some number of them will always be left back in the hotel depending on time of day and what we are going to do. Once at my destination only a couple/trio make it out of the hotel room at a time.
Also for m43 bodies I only have my single E-M1.1 for normal photography. No two bodies with two lenses mounted outings unless I am bringing the IR converted E-P2 camera as well but that is a special case camera.
There is definitely something to be said about having too many choices and only acquiring what you really want and will actually use rather than everything that comes along. But the flip side, as others have said, no need to artificially restrict yourself to some small number of lenses for "just because" reasons.
Yes, but because that is all you want to use I presume. You didn't decide one day to punish yourself by not allowing yourself anymore?
Depends a bit of what I am up to, but the PL 8-200, and 1.4TC is a very nice "serious" combo for the heavy lifting.
