make no mistake, physical cameras are out there and people are beginning
to talk
heres what one says


1. Much smaller and lighter lenses.
2. Smaller bodies.
3. Quieter (no mirror slap).
4. Electronic viewfinder (state of the art EVF, flexible dynamic
information overlay, exposure and white balance real-time preview,
magnified critical focus, alignment grids, face detection, focus tracking,
versatile AF point selection across entire frame, big view, bright view,
clear view - all info off, etc.)
5. Backwards compatible with Four Thirds lenses via spacer adapter. Full
exposure funcionality. AF function retained - though AF will be slower
with many Four Thirds lenses.
6. Compatible with Four Thirds flash system.
7. Potential for implementation of high quality digital video recording


1. Electronic finder, despite versatility not everyone's cup of tea.
2. Bodies and lenses too small for some?
3. No compatibility for Micro FT lenses with standard Four Thirds bodies.
4. Slower contrast detect AF compared to phase detect AF on DSLRs.
5. AF less usable in low light without AF illuminator.
6. Electronic finder performance and clarity drops as brightness of scene
