Nice shots, some of your best so far I think :clapper:

 

It does look like you needed a bit more speed though - little birds are constantly making tiny fast movements, so you need at least 1/500 to be safe... Hard to tell from pics this size, it could be that the focusing is very slightly off? Might be worth checking the focus on the lens? Does your camera have AF micro adjustment settings? (It'd be in the custom functions) If so you can set the camera up for a particular lens if you do find it back focuses.

 

If you turn the ISO up too high you'll probably find that the camera will over-expose a little, so compensate for that too.

1/250, @ f/9.5,iso400, 214mm hand held. and, it was overcast like it was going to rain, low cloudage.(on 100iso the shutter speed was coming it between 1/8 low down to about 1/40'th through the tree's at the sky'ish, had a couple 1/80'th.)

 

i dont think the camera does have an AF thing, does have 'camera lens data enable/disable' but i havent read the insruction to that bit, i'll have a look.

 

 

edit...i tried a higher iso, 800 started to look very pale...1600 well, noise it out lol.

Ah, the perils of having a camera with millions & millions of mega pixels... I'm disregarding the 7D as a new camera option because of the noise issues :no: With the 500D 800 ISO is probably about as much as you can get away with, even then best to stick to 400.

 

For birds against a bright sky spot meter on the birdie - it doesn't matter if the sky is a bit blown as long as the main subject is ok.

 

At 1/250th of a second at over 200mm you barely have enough speed to guarantee no camera shake, remember that the speed should be at least equivalent to the focal length of the lens to be sure of sharp images.

 

Do the lens tests anyway, it's almost as much fun as zeroing your scope... :laugh:

read the manual a couple of times, then went to the disc manual... the periferal corection thing sais 'register a lens to the camera' etc etc, 'it'll even out any darkened cores etcs, alas, it only corects for the listed canon lens's, or at least as far as i can see, but it read stick a lense on register it and it'll sort the periferals as the jpeg does, (aplies it to RAW)... did i miss something Kathy? lol. it wont register the sigma.

 

hmmm the lens test, which one?

 

 

edit...you should try 1/30'th on 300mm lololol any iso.

Did you miss something? Oh dear... :no: NO, it probably wouldn't register the siggy, or the Tamron, but I doubt you have a problem with vignetting (if that's what you meant) with either of those lenses?

 

Don't worry about it - I had a look at specs & your camera doesn't seem to have the AF micro adjustments anyway. You can still test the lens focus by faffing about photographing rulers at 45 degrees or targets at measured distances. Life's too short though, innit?

 

I have tried 1/30 at 300mm... it doesn't really deliver the goods but it's slightly better if I rest long lenses on my zimmer frame.

 

Doesn't matter what ISO you use but all cameras will find it harder to focus and slow down a bit in low light and low contrast conditions.
