I'm 61, retired, to shaky to hand hold with out IS. Photography for me is just a hobby. I've used Pentax and Oly side by side almost every day in the Philippines. Six months, one year, five months(departing again september). E520-11-22&35, 90% of my shoots. E-1, L-1, pany 25, stay in storage in the U.S. I have resisted E620 cause don't want two different battery's. But the reality is that I have a hard time getting back up after low shoots on my Knees so articulating screen could be usefull. I'm looking for a retirment body And there is the EP-2 now with tilting view finder, old eyes can see. Profestionals say they know a new camera after 5,000 shoots, takes me about 10,000 shoots. If I get the Pen I will shoot it along side 43rds body when convenient and will take about two years to know it's limitations and be comfortable with it cause I'm a dumb s... . I will not give up 35&11-22 untill M43-9-18&17 satisfys me or to old to carry it. I gave up on looking for the best shoot and light. Documenting daily life in the mountain villages and the city is what I do. No portrates or macros. Any advice for use old guys getting less physicaly capable every day? Would you be happy with just the pen?
