Sony Cyber-shot DSC-T90 12.1MP Digital Camera with 4x Optical Zoom and Super Steady Shot Image Stabi Your Oly E-P2 is overall an extremely nice camera. Compared to the Panasonic G1 (the other m4/3) this is a bit heavier. Image quality using RAW is fine at low to channel ISOs; marginally acceptable at 400 and above. The separately purchased eye-level viewfinder can be of excellent image quality, comparable to the Panasonic. One great advantage in this viewfinder over the G1 is that you could tilt it up which also comes in very handy when carrying out low-level shots.
The biggest weakness from the system is the paying attention. Again, compared to the G1 the particular focusing is sluggish and at times a bit erratic. Since most of the photography is landscape images, this is not a serious drawback for me, but might be significant for somebody shooting action stuff.
Both the Oly plus the G1 have a four-way turn on the back at the low right. I often happen to accidentally press among the buttons which brings upward an in-viewfinder menu while i don’t want it. Again, a minor inconvenience. » Read more..
