After long consideration of micro 4/3 with Panasonic and Olympus modes vying for my attention, I finally decided on the E-P5. Why?
Brilliant handling in my hands. I stress 'my' because the feel of a camera and its fit in the hand depend on personal characteristics as much as the size, weight, feel and positioning of controls. I like the controls: their placement, readability, positive indents and ease of use.
The rear screen image and superimposed detail is brilliant. The VF4 viewfinder is a must for me in many situations as I have long sight. The diopter adjustment at max is necessary in my case for me to see find detail. I can manage OK with the back display, but it is too close to my eyes to see in focus without spectacles. Good enough for framing, and I can see OK manually focus assist - which is amazingly useful. But with the VF4 I can go a little further in accuracy terms.
You can view the specification online. Yes the 1/8000 is useful at times, but hey I am still in the early days of exploring the capabilities of this camera.
