Yeah, as a viewfinder, the DSLR optical path is not that great. In
particular it's not flexible. I'm still annoyed that tilt/swivel LCD
screens seem to be treated as a consumer feature, and actively excluded
from prosumer cameras and up.

You need a monster tripod to give you stability at that length, too,
though. IS can only do so much.

Nope. That's the whole point of [Micro] Four Thirds -- multiple
companies making bodies and lenses that all work together. Panasonic
lenses work fine on my Olympus body, with AF, auto aperture, auto
exposure, and so forth.

You should be more than "willing"; power zooms are very hard to control,
and much slower to work with.

This is confusing; because "kit lens" is exactly what you're

You won't get out to 800mm-equivalent with dedicated micro four thirds
lenses at a sane price. But you can get out to 600mm for about $600, so
that's *so much* better than 35mm.

Good choice.

One of your big choices is IS in the body, or in the lenses. Olympus
bodies have IS, Panasonic do not, they put theirs in the lenses.
In-body IS works with any lenses, including c-mount video lenses on
adapters (i.e. totally mechanical, very old-school, lenses).

You've got that sort-of backwards. It's not "multiplier for 35mm
lenses"; it's "multiplier to give 35mm equivalent focal-length".
And the answer is 2x. A 300mm lens on a micro four thirds body gives
the angle of view of a 600mm lens on a 35mm body.
You can get adapters for a huge range of lenses to micro four thirds.
Mostly they're cheap mechanical adapters for old lenses, so that means
manual focus. Even the adapters for modern AF lenses rarely (never in
my experience, but some may exist) give you AF.
