ok a few weeks ago i posted a image of a grey wagtail on a stick one comment was that it looked like it had front focused.
so today i tried a little front/rear focus test like the one below.

i have however noticed that lots of my images when viewed large seem slightley off especially with my sigma 150-500 im guessing i need to work on my
technique and keep the lens still a it better.

cheers

Really you also need to do a controlled test shot using the lens with which the issue was originally raised.

ok james i try it tommorow with the 150-500 if the light is any better plus i will need to do it outside as the minimum focus distance is 3.5 metres
thanks for taking time to reply
