Had the opportunity to do a field test on the latest of the Olympus Pen Series, the Olympus EPL-2.
Comparison Pictures with the Olympus EPL-1
The button layout has changed alot and Olympus has added a dial for easier and faster control of the functions. It took me awhile to get used to the button layout using the EPL-2.
Lenses: Comparing the EPL-2 kit lens of 14-42mm Mark II m4/3 with the EPL-1 14-42 Mark I m4/3 . You can see from the top view of the comparison pics, the lens cap can be seen sticking out a little. The zoom and focus of the Mark II lens is much smoother compared to the Mark I.
Autofocus: Apparently for me, the autofocus for the EPL-2 is slightly faster compared with the EPL-1.. but i've yet to have a chance to really test it during low lightings which for the EPL-1 is slow at auto focusing.
