I used to use a Canon S3, which only had buttons to adjust the focus. I would have really liked a wheel. When you say "slow", do you mean it's difficult to reach, or that it takes a lot of turns to get it where you want it? I think I read that the wheel on the SX30 changes focus more if you turn it fast, less if you turn it slowly. Can anyone confirm that?
When I say slow, I mean that the focus ring moved the focus slowly. It required a lot of turns to get anywhere.
Does it have a setting to enlarge the middle of the EVF as soon as you start manually focusing? That's very helpful, and in my opinion potentially better than an SLR if the EVF resolution is reasonable (most aren't).
My camera does have that, but I don't use it, I find it quite off putting. That may be just me though.
Are you saying that it wobbles around too much as soon as you try to adjust the focus? I don't think I had that trouble, even with a 1.7x teleconverter on. Are you holding the end of the lens with your right hand? Or does the position of the wheel force you to let go of the camera? Can you reach it with your thumb without letting go? Maybe it takes practice.
Yes, it wobbles around too much because of the high magnification. The little horizontal wheel on the back of the FZ100 has notches and as you rotate the wheel it jerks the camera. After you activate the wheel you can then use the left and right arrows on the D pad. That is quite fast and smooth, but its an extra thing you have to do and most birds aren't prepared to sit around and wait for all that to happen.
The problem I had was that the MF button on the S3 could only be reached with the left thumb if I held the lens at the base. I ended up taping an icypole stick to the side of the lens so I could press it without moving my hand.
