True, it is still a 400, but the angle of view is an 800, right? So
the shake would be moving the lens the equivalent of what an 800
would see on a full frame, right? I am so confused with all
this. It is like a 400 with a 2x converter that only sees the
center portion of the field.
Now you've got it, Aram! It is very much like a 400 with 2x
converter. I like to think of it as a 400, where you can crop half
the image area away, and still have 10 mpixels to work with. Sort of
like a 50% crop on a 20mp camera. (In this case, the 505 crop is
done for you, whether you need it or not!)
Of course, the trade off is that cramming 10mp in that small an area
means fewer photos per photosite, and thus more amplification is
needed, and thus more noise. However, Oly went out of their way to
reduce the space between the photosites, in order to make them a wee
bit larger. The reviews seem to all indicate that noise levels, at
ISO 400 and down are much the same on Nikon, Canon and Oly. At
higher ISO's the others win. However, noise is not so bad.. and, so
far, the noise I've observed is about the same level as the DMR,
which had higher levels of noise than the Canon equivalents, but was
still very manageable.
Olympus put a lot of noise reduction stuff into their cameras, to
compensate, but, as always, noise reduction softens the image. If
you turn all that junk off, the final image, in visual quality and
noise levels is very similar to the DMR.
That and the marvelous finder (very similar to the R8) is what sold
me on the camera.
Cheers!
