Quote: Alright, the DA* 60-250/4 it is. Can you use it without a tripod, handheld?
From all the research I've done, that's is just a really bad question to ask. It's not about the lens, it's about the focal length. You can't hand hold any 300 mm lens and get as good results as you would on a tripod. If you don't believe me, I suggest you take your camera outdoors and give it a try. Even at 1000 of a second, there will probably be a noticeable difference in pixel comparisons. Hand held is for short focal lengths, and even then a tripod is probably better.
