I'd rather just ditch the mirror altogether. It's the biggest weakness of SLR's, since it affects AF accuracy and VF focusing accuracy. EVIL is inherently more accurate for both manual focus and AF since you're focusing off the imaging sensor itself. Don't ditch the LCD until you've spent time with a good Live View camera with a flip/twist LCD. It changes the game entirely. > >> The moment I think of EVF I also think of a mirror-less camera, with a >> distance from lens mount to sensor as reduced as possible, with new >> lenses to exploit the advantages AND a very good adapter to the former >> lens format of the brand.

No lens-based shutter systems. And the introduction of digital nearly completely devalued optical design in the body.

It's also possible that he's actually read the bitching on the comments about the E-420 pointing out that he picked the camera with the worst VF and worst ergonomics in-class and realized that he should have either gone with his first choice (any low-end DSLR) or picked a camera that actually delivered on its promises (like the K-m or A200). -- M.
