A couple days ago I was outside and taking some pictures of the kids in the yard. My boys were running around doing something, and I had the camera on one of them with the shutter half pressed to focus. I was keeping it there for a few moments waiting to take the picture as I followed his movement, and I noticed the camera would seemingly lose focus for a very quick fraction of a second. I didn't time it, but it was a repetitive thing happening about every 3-4 seconds. I didn't notice it affect any pictures, but it was very noticeable before taking a picture. Now usually I use the LCD, but this time I was actually playing around with the EVF. I'll have to try it again and see if I notice it on the LCD, or if I can time it to take a picture right when it happens; but I wondered if anyone else has noticed this and if it's normal. I'll have to check, but I think it's set to AFF.
