So my gf and I went out to watch the local fireworks show. Of course I brought along my camera and tripod. I don't have a cable release, but I figured I could give enough on the timer delay for some decent shots. Two problems cropped up. The first is unrelated to the camera. A tree was basically in the way. We had no idea where the fireworks were going to be from, so most of my pictures have a tree or cropped top of a tree in them. Location was important, and we though we were in a good one. We had no idea what type of fireworks and the exact spot that they were going to be lit from.
The second issue is focus point. Everything I had read is that setting the focus point ot infinity should be suffecient. Most of the pictures look a tad out of focus, and I noticed maybe why. If I turn the camera off and back on with reset lens set to on, the lens should be set to focus at infinity. But if that were the case, then why can I turn the lens ring toward infinity, and objects within the frame go slightly blurry(and I can here the focus movement in the lens). I guess what I mean is, if I turn the camera on and off with reset lens on, the camera actually has the focus point set to somewhere between rotating the ring all the way left and all the way right. Is this truly infinity?
Secondly, is my assertion correct about fireworks? Should the focus point be set to infinity? Almost toward the end of the show, I manually focused on the fireworks as they were going off, and got two that were slightly sharper than the rest.
