If IQ at 300mm is your primary criteria, go for the 300mm f4! :-) ...or perhaps the 100-400mm But of the choices listed, the Panny might have a (very) slight edge ... being a tad brighter, you can ...

Luton Camera in the UK can supply many Olympus parts, maybe let Advance know about them http://www.lutoncameras.com/ Olympus likes full control of things like parts, repairs, firmware.

If Olympus has two assembly lines... One using military spec components that turns out cameras built like tanks and one using marginal components and shoddy assembly.  So far, I've yet to get a ...

The more I think the ideal focal length would be around 120mm. first, it's 2x 60mm so it would make sense to some to own both, where as 100mm may not be different enough and many would opt for one ...

'Mother of OM'

OM-F (for Fullframe) OM-A(alpha) if they go w the Sony mount) OM-35 OM-OV (oversized) OM-2x

With an 8:6 format sensor :-)

At least until the E-M1/II comes out! ;-)

or faster?  2.8 would keep the size down. Ideally no larger than the 17/1.8 Might trade in my 9-18 for such a lens. Perhaps one of Oly's promised f1.2 lenses will be UWA, but even if such a lens ...

Be sure to check the Olympus store for sales and refurbs... I like the snap focus ring on the 17, some hate it.  try if you can before you buy. The Panny is faster, but larger Picked up the ...

using the 40-150 w extension tubes? Or picking up an adapter for your Sigmas? One lens I liked for skittish insects was the 70-300 (1:3 macro) which I sometimes used w the EX-25  Had plenty of ...

with the E-3 and E-30. and E-520.  These had a too heavy AA filter, and detail was indeed lost.  I know I could never get as sharp an image from my E-520 as I could w my 500 using the same lens. So ...

Too big to be portable, not big enough to be big. If I wanted big I'd go w this one. And it's even portable! http://www.raymondboyd.com/?page_id=4322

Out of curiosity I opened up one of my generic batteries... rating on the cells was considerably less than what the external label stated.   They were cheap enough though, and three plus years are ...

1) Just getting used to 16MP, couldn't possibly handle 100MP...  Maybe in another ten years. 2) Won't fit in my pocket.

From reading that thread, it sounds like the issue described is a common problem w that camera and may not be related to moisture.  'Water in body' was just a convenient excuse for denying ...

Got several of m43 lenses, three bodies... no interest in unloading all that to swap systems, insufficient funds to run dual systems. I like my 17/1.8 Is there a comparable (in size, quality, cost) ...

I'd rather have an external GPS w its own battery, connected to the camera via cable or that connector under the hotshoe.  (maybe optional WiFi hookup to GPS or smartphone, but that will draw down ...

Just split the difference and go for a 17mm prime... or maybe a 15 and 25. Unlikely anyone would make a zoom with less than 2x. Just consider some of the zoom lenses out there... 7-14, 9-18, 10-20, ...

-slightly- better... a little more detail. But I wouldn't say vastly better.
