Hi there, I'm looking for a recommendation of the "right" lens for getting good shots of my toddler indoors with my EM-5. I have the Panasonic 20mm, which I love as I can pocket the camera and it seems to focus fast when outdoors in daylight. Sometime is takes too long to focus outdoors, and it definitely hunts indoors many time missing the moment. Maybe this is the right lens, I'm using it wrong, and someone can give me tips on how to better keep up with my son. I also have the Olympus 45mm, which is fast indoors or out, but it is tricky to get more that half-body shots indoors unless it is a large room. I guess that leaves the Panasonic 25mm, which might be a bit large/heavy, or the new Olympus 17mm which might be a bit wide? If it is the Panasonic 25mm that would work the best, has anyone ever seen it go on sale, or is it always $499? Thanks for any responses!
