Autofocus (Part 2) & Image Stabilization

While I previously whined extensively about the disadvantages of “square AF” (particularly on the E-P1), there is also a bright side to this new style of autofocus, which is that you can place your AF square anywhere you like on the frame. Of course, this is also possible on DSLRs with multiple focus points but it tends to be a higher end feature.

The E-P1 and GF1 were also designed with video recording in mind and both cameras continuous AF modes are quite capable. You can “set” a subject and have the camera automatically track it around the frame, it’s quite neat. I have yet to make much use of it though.

Anyway, moving on. There is a feature that I had underestimated on the E-P1 that keeps it in the running against its GF1 competitor and that is image stabilization. I have been using mostly the GF1 body with the 17mm and the 20mm these last few days and for about 30% of the lower shutter speed photos (i.e. 1/30 and less), there has been noticeable camera shake in the photos. On the E-P1, I only notice it about 5% of the time. Even at short focal lengths such as 17mm and 20mm, image stabilization can help. Apparently the mechanism adds a bit of weight to the camera but I think it’s a feature worth having.
