nice shots for first attempts ! I still ain;t no good at bird shots but there are a few here that are not bad at all. Regards getting sharp shots - the rule that I came across states that to get a sharp image:

Shutter speed= 1/focal length (Applied to 35mm cameras)

so if your shooting something at full 12x zoom, you'd need at least 1/420s to get a sharp image.Now you may also have to take into account the size of the sensor ( I read that as well) but for now I'd use that as a rule of thumb. So you could say f4-5.6 (which I think is the FZ's sweet spot) and a minimum 1/420s should get you a pretty sharp and in focus shot.

Cheers

Harjtt,

Basic rule of thumb which I bypassed in the Red Cardinal shot !

Others seem to me to be reasonaably sharp - once I increased the ISO and used a faster shutter speed !

Thanks for your input and comment.

Robin.

Hi Robin, its been stated elsewhere on the net that the I.S system on the FZ`s should give you a latitude of a couple of F stops from the basic rule Harj posted, so 1/320th should have been ok to get a sharp pic.
Looking at the shots more closely, it seems on shot 2 the camera focussed in front of the bird onto the branch, which i`ve found a common problem with the autofocus on my FZ20. Sometimes its best to lock the focus onto something at the same range as the bird in such cases, then recompose the shot (if you have the time, often they fly away or shift position before you can do this).Alternatively using a greater DoF will get the bird in focus too if the focus is slightly out.
I`ve posted the following shots previously on here, but they both illustrate that you can get sharp shots with lower shutter speeds than the rule suggests......both are taken with a tcon-17 added, so focal length was over 700mm at full zoom.

Here`s the exif data for the first shot, as it`s been run through neat image which strips the exif.The image has been cropped too so the bird fills the frame better.....

By the way Pete, the bird you were asking about is called a Common Grackle.

Super shots, Mark !!! Maybe, if I keep working at it, I might get half as good some day !!!

I think Happy's point about the Cardinal was that the bird was moving, not so much the camera. The perch seems sharp, but the bird is blurry. If so, IS won't help much - only shutter speed.

Thanks, as always, for your enlightened input.

Robin.

P.S. I liked Happy's pic of the Cardinal peeping out from among the branches - had a mischievous look in his beady little eye.

Hi Robin, yes you`re right the Cardinal was definitely moving , looking at how sharp the branches are surrounding it. Burst mode may have helped there.

I was referring to the rule HarjTT mentioned about shutter speeds vs focal length when talking about the I.S.

Thanks for the comments about the shots.

Mark
