I just picked up an EF 85mm L and wanted to give it a shot. I had a practice photo shoot today with some friends of mine and their 4 year old. We headed to the park across the street as the setting. The sky was clear and it was pretty sunny. I found it difficult managing my camera settings (I shoot in manual) and trying to get the kid in focus. Since I like to keep my background out of focus I switched to Aperture Priority. Or should I have stayed with Shutter Priority since the subject was constantly on the move?
What should I have done differently with the lens? I ended up taking it off. I just found it too slow for this situation. I have the EF 85mm f/1.8. I was planning on selling it since getting the L prime. But now I think I am going to keep my 85mm f/1.8. It is faster at focusing. Would that have been a better lens to use today?
I am just looking for some pointers on camera gear and setup for shooting kids that will not stay still for longer that 0.1 seconds. Non studio work.
